In addition to a normal display area (dot matrix display section), An icon display section for displaying a power-on state, an operation mode, a specific message, and the like is also provided.

According to such information terminals, particularly in portable terminals, low power consumption is required for liquid crystal display devices.

For example, using a reflection type liquid crystal display device,
A technique for reducing power consumption by operating the dot matrix display unit by time division driving and operating the icon display unit by static driving and displaying only the icon display unit in a standby state has been proposed. Kaihei 11-2
No. 81961).

[0005] Further, in the conventional portable terminal, a monochrome liquid crystal display device has been the mainstream, but in recent years, with the increase in the amount of information, the trend toward colorization has increased.

However, according to the liquid crystal display device disclosed in Japanese Patent Application Laid-Open No. H11-281961, the dot matrix display is displayed in color using retardation without using a color filter. As a result, the display colors are considerably limited, and the utility value is reduced.

In recent years, a reflection type color liquid crystal display device using a color filter has been proposed. This device will be described with reference to FIGS.

FIG. 4 shows a liquid crystal display device 1 used for a mobile phone.

For example, in a mobile phone, a reception sensitivity display unit 5 that displays the reception sensitivity of an antenna and a battery that displays the remaining capacity of a built-in battery are provided. A capacity display unit 6 is provided.

The dot matrix display section 4 is a simple matrix type display system, and is composed of a striped X electrode group 7 as a signal electrode and a striped Y electrode group 8 as a scanning electrode. The electrode groups 7 and 8 are opposed to each other while being orthogonal to each other.

The intersection (dot) between the X electrode group 7 and the Y electrode group 8 becomes each pixel.
During the period 8, a drive voltage is applied to a predetermined dot, and ON / OFF is performed by not applying the voltage, thereby turning on or off each pixel.
Information (data) such as abbreviated telephone numbers, transmission dial numbers, and message information is displayed.

In the liquid crystal display device 1 provided with the above-described icon display unit 3 and dot matrix display unit 4, a specific colorized configuration will be described with reference to a color liquid crystal display device 2 shown in FIG. In this device 2, the icon display section 3 is displayed in monochrome, and the dot matrix display section 4 is displayed in color.

Two transparent substrates 9 and 10 are arranged so as to face each other, and a liquid crystal layer 11 is sealed between them by a sealing material 12 arranged in a frame to form a liquid crystal cell.

On the inner surface of the transparent substrate 9, a common electrode 13 for displaying an icon and a signal electrode 14 for a dot matrix display (corresponding to the X-electrode group 7 in the form of stripes) are formed by ITO or the like. An alignment film (not shown) is formed thereon, and rubbed in a predetermined direction.

On the outer surface of the transparent substrate 9, a polarizing plate / retardation plate 15 is provided. On the other hand, in the transparent substrate 10, a conductive light-reflective or light-semitransmissive layer (hereinafter, referred to as “metal”) made of a metal such as Al, Cr, and Ag is formed on the inner surface thereof.
Reflective layer 16) and color filter layer 17
(Colored layers composed of three colors of red (R), green (G), and blue (B)) are sequentially laminated, and formed on the color filter layer 17 with ITO or the like. An icon display data electrode 18 and a scanning electrode 19 (a stripe-shaped Y electrode group 8) for a dot matrix display section are formed. The signal electrodes 14 and the scanning electrodes 19 of the dot matrix display section are arranged to be orthogonal.

The reason why the color filter layer 17 is extended to the icon display portion is as follows.

That is, the cells of the dot matrix display section
Gap d₁And cell gap d of the icon display section_TwoAll together
If not, display irregularities may occur in both cases.
Yes, to solve this problem, both display sections
And retardation Δnd ₁And Δnd_Two(Δn; multiple of liquid crystal
Index of refraction) must be equal,
The filter layer 17 is formed up to the icon display section.

At this time, the color filter layer 17 is formed in a stripe arrangement in which R, G, and B are alternately arranged in order to match the wiring shape of the signal electrodes 14 and the scanning electrodes 19 for the dot matrix display section. The stripe arrangement is extended to the icon display section.

According to the color liquid crystal display device 2 having the above configuration, the display screen is provided with the icon display section and the dot matrix display section, and the icon display section is driven statically and the dot matrix display section is driven in a time-division manner. .

In order to display an image on the dot matrix display section, a voltage is applied between the signal electrode 14 and the scanning electrode 19, and a driving voltage is applied to each dot, whereby the liquid crystal layer 11 is formed.
, An electric field is generated and turned on / off, and information (data) such as message information is displayed.

[0022]

However, according to the liquid crystal display device 2 having the above-described structure, the display becomes unclear because the color filter layers 17 arranged in stripes are provided in the icon display section.

That is, the shape of the pictogram display portion of the mobile phone, for example, the reception sensitivity display portion for displaying the reception sensitivity of the antenna, the battery capacity display portion for displaying the remaining capacity of the built-in battery, and the like are determined by the icon display data electrode 18. The color filter layer 17 is arranged in a stripe pattern behind the pattern, especially at the boundary of the pattern, and the color filter layer 17 has a stripe shape. The portion protruding from the pixel becomes large, whereby each pixel composed of R, G, and B dots is prevented from being mixed in color with the same area, and as a result, a portion in which another color other than white or black is displayed occurs. As a result, the entire icon display section was not sharply displayed, and appeared to be blurred.

The present invention has been completed in view of the above, and an object of the present invention is to provide a high-quality color liquid crystal display device which has achieved a clear monochrome display on an icon display section.

Another object of the present invention is to provide a high-performance portable terminal or display device equipped with such a color liquid crystal display device of the present invention.

It is. FIG. 9 shows an arrangement of each color layer of the color filter in the icon display unit according to the present invention, and FIG. 10 shows an arrangement of each color layer of the color filter in the conventional icon display unit. Note that the same portions of the liquid crystal display device shown in FIGS. 4 and 5 are denoted by the same reference numerals.

In the liquid crystal display device 21 shown in FIG.
Reference numeral 0 denotes a transparent substrate as the one substrate, and 9 denotes a transparent substrate as the other substrate.
For example, a liquid crystal layer 11 made of a chiral nematic liquid crystal twisted at an angle of 200 to 270 ° is sealed with a frame-shaped sealing material 12 to form a liquid crystal cell.

In such a liquid crystal cell, a dot matrix display section 22 and an icon display section 23 are formed.

On the inner surface of the transparent substrate 9, a data electrode 24 for icon display and a signal electrode 14 for a dot matrix display, which is the other stripe-shaped transparent electrode group, are formed by ITO or the like.

Moreover, in this embodiment, it is desirable to provide a dummy pattern 25 around the icon display data electrode 24.

Further, an alignment film (not shown) made of polyimide resin or the like is formed on the icon display data electrode 24, the signal electrode 14, and the dummy pattern 25, and rubbing is performed in a predetermined direction.

On the outer surface of the transparent substrate 9, a polarizing plate / retardation plate 15 is provided, for example, TN (twisted nematic) mode, STN (super TN) mode,
They are arranged in a predetermined direction according to an operation mode such as a D-STN (double-STN) mode or a normally white mode / normally black mode. Note that only a polarizing plate may be used instead of the polarizing plate / retardation plate. When the reflection layer 16 is a light transmissive layer,
A polarizing plate and a retardation plate are also arranged on the outer surface of the transparent substrate 10,
In addition, a backlight is provided outside thereof.

On the other hand, on the inner surface of the transparent substrate 10, a light-reflective or semi-transmissive layer (hereinafter abbreviated as a reflective layer 16) and a color filter layer 17 are sequentially laminated.

The color filter layer 17 is a color filter layer 17a corresponding to the dot matrix display section 22.
And a color filter layer 17b corresponding to the icon display section 23.

The common electrode 26 for displaying icons made of ITO or the like is formed on the color filter layer 17b, and the scanning electrode 19 for the dot matrix portion, which is one of the stripe-shaped transparent electrode groups, is formed on the color filter layer 17a. Have been.

The signal electrodes 14 for the dot matrix section and the scanning electrodes 19 for the dot matrix display section are arranged so as to be orthogonal to each other. One pixel of the dot matrix display section 22 has R, G, B It is represented by 3 dots.

The reflection layer 16 is made of, for example, Al, Cr, Ag
It is made of a conductive metal, a dielectric layer, or the like, and is made substantially light-reflective by increasing its thickness, or semi-transparent by making it thinner. The reflecting layer 8 may be specular or scattering, and in order to provide scattering, it can be obtained by forming an uneven shape with a resin or the like and forming a reflecting layer thereon. .

Further, an alignment film (not shown) made of a polyimide resin or the like is formed on the common electrode 26 for displaying icons and the scanning electrode 19 for the dot matrix portion.

In this embodiment, the reflection layer 8 is made of Al, Cr,
When made of a conductive metal such as Ag, as shown in FIG. 3, the dummy pattern 25 and the common electrode 2 for icon display are used.
It is preferable that 6 is electrically conductive and both have the same potential.

For this purpose, for example, the sealing material 12 may be made of a conductive material, and the dummy pattern 25 and the common electrode 26 for icon display may be extended to directly below or directly above the sealing material 12, respectively. . Alternatively, if the conductive sealing material 12 is not used, a conductive material such as an Ag paste may be separately provided in the liquid crystal layer 11 and electric current may be supplied using the conductive material. The dummy pattern 25 and the common electrode 2 for displaying icons
6, the same voltage may be directly applied from outside.

As shown in FIG. 1, the pictograph display section 27 (for example, in a portable telephone, a reception sensitivity display section for displaying the reception sensitivity of the antenna and a remaining capacity of the built-in battery are displayed by the icon display data electrode 24). And a dummy pattern 25 (hatched portion) surrounds the pictogram display portion 27 (icon display data electrode 24).

Next, the color filter layer 17b disposed on the icon display section 23 will be described in detail.

First, the color filter layer 17a arranged in the dot matrix display section 22 will be described.
Reference numeral 7a denotes a stripe arrangement shape. As shown in FIG. 10, many R coloring layers are arranged along a column of pixels, and similarly many G coloring layers and many B coloring layers are repeatedly arranged in that order. ing.

On the other hand, as shown in FIG. 9, the color filter layer 17b has a R, G, and B delta arrangement. In the figure, the dots arranged in the delta form have a quadrangular shape, but they may be circular or polygonal such as hexagonal.

As described above, the icon display section 23 is patterned by the icon display data electrodes 24, but is formed in a delta arrangement behind the pattern, especially at the boundary of the pattern. By forming the formed color filter layer 17b, a portion protruding from the boundary line is reduced, whereby each pixel composed of R, G, and B dots is easily mixed with the same area, and as a result, A portion in which another color other than white or black is displayed no longer occurs, or the degree of such occurrence is reduced, and the entire icon display portion is sharply displayed, and the blur is not visible.

The icon display section 23 having such a configuration performs a static drive, and therefore a predetermined voltage is always applied to the common electrode 26 for icon display.
Then, by arbitrarily applying a voltage to the data electrode 24 for icon display, an electric field is generated in the liquid crystal layer 11 and ON / OFF of display is controlled.

The display contents of the icon display data electrode 24 are usually displayed in the dot matrix display section 22.
It is good to make it larger than about 16 pixels × 16 pixels in the point of viewability.

Thus, according to the liquid crystal display device 21 of the present invention, since the color filter layer 17b is formed in a delta arrangement with R, G, and B, the entire icon display portion is sharply displayed, and blur is visible. As a result, a clear monochrome display can be achieved on the icon display unit 23.

Further, since the dummy pattern 25 has the same potential as the common electrode 26 for displaying icons, the liquid crystal layer 11
No electric field is applied to the image, no white spots occur in the case of the normally black display, and a problem such as a black light in the case of the normally white display does not occur.

In addition, the icon display data electrode 24
And the dummy pattern 25 provided therearound,
The cell gap becomes equal over substantially the entire surface of the icon display section 23, and thus, the phenomenon that the background of the icon becomes blank when no voltage is applied as in the related art does not occur.

Note that the color liquid crystal display device 21 having the above configuration
In the above, the icon display data electrode 25 is formed on the transparent substrate 9 and the common electrode 26 is formed on the transparent substrate 10. Instead, the common electrode 26 is formed on the transparent substrate 9 and the transparent electrode 9 is formed. Data electrode 2 for icon display on substrate 10
5 may be formed.

In the above example, the color filter layer 1
Although 7 is provided on the transparent substrate 10, it may be on the transparent substrate 9 side. (Mobile Phone of the Present Invention) A mobile phone 28 equipped with the liquid crystal display device 21 will be described with reference to FIG.

And an icon display unit 23. Also, housing 2
An antenna 30 for transmission / reception is provided on the upper part of 9, and a receiver 31 and a microphone 32 are formed on the surface.

The reflection layer 16 is constituted by a light-reflective or semi-transmissive layer. When the reflection layer 16 is light-reflective, the liquid crystal display device 21 becomes a reflection type liquid crystal display device. When the reflection layer 16 is translucent, the liquid crystal display device 21 is a transflective liquid crystal display device. (Portable Terminal of the Present Invention) A portable terminal 33 provided with the liquid crystal display device 21 will be described with reference to FIG. The mobile terminal 33 is shown as various information terminals other than the mobile phone 28. For example, watches, calculators, game consoles, pedometers,
Examples include, but are not limited to, GPS, POS, handy terminals, and industrial instruments.

In this portable terminal 33 as well, the liquid crystal display device 21 is disposed in a small casing 34, but the liquid crystal display device 21 has a dot matrix display section 2 in the display area.
2 and an icon display unit 23.

When the reflection layer 16 is light-reflective, the liquid crystal display device 21 becomes a reflection type liquid crystal display device,
When the reflection layer 16 is translucent, the liquid crystal display device 21 is a transflective liquid crystal display device. (Semi-Transmissive Liquid Crystal Display) A case where the liquid crystal display 21 of the present invention is a transflective liquid crystal display will be described with reference to FIG.

A retardation plate 35 made of polycarbonate or the like and an iodine-based polarizing plate 36 are sequentially stacked on the outer surface of the transparent substrate 9 of the liquid crystal panel, and a retardation plate 37 made of polycarbonate or the like and an iodine The polarizing plates 38 of the system are sequentially stacked. These are attached using an adhesive made of an acrylic material.

Further, a backlight 39 is provided on the polarizing plate 38. In the backlight 39, a light source 41 such as a cold cathode tube or an LED is disposed on an end face of the light guide plate 40, and the light emitted from the light source 41 is introduced into the light guide plate 40, and the light guide plate 40 emits light to the liquid crystal panel.

In a liquid crystal panel, a signal electrode 14 and an alignment film (not shown) made of polyimide resin rubbed in a certain direction are provided on a transparent substrate 9 such as a glass substrate.
Are sequentially formed. Note that an insulating layer made of SiO ₂ or the like may be interposed between the signal electrode 14 and the alignment film.

A semi-transmissive film 42 is formed on the inner surface of a transparent substrate 10 such as a glass substrate, and the color filter 17 is provided on the semi-transmissive film 42. Further color filter 1
A thin film made of a metal such as aluminum or chromium or a black matrix which is a light-shielding film formed of a photosensitive resist may be formed between the light-emitting elements 7.

Then, on the color filter 17, SiO
₂ and an overcoat layer 43 made of a resin, the scan electrode 19 and an alignment film (not shown) made of a polyimide resin rubbed in a certain direction on the overcoat layer 43.
Are sequentially formed. This scanning electrode 19 is orthogonal to the signal electrode 14. Note that an insulating layer made of SiO ₂ or the like may be provided between the scanning electrode 19 and the alignment film.

The semi-transmissive film 42 has both light transmissive and light reflective properties, and prevents a phase difference from occurring when sandwiched between two polarizing plates. In addition, the semi-transmissive film 42 may be specular or scattering.
In order to produce the semi-transmissive film 42 having a scattering property, a semi-transparent film may be formed thereon by forming an irregular shape with a resin.

The color filter 17 is of a pigment dispersion type,
That is, a photosensitive resist prepared in advance with a pigment (red, green, blue, or the like) is applied on a substrate and formed by photolithography.

Each of the transparent substrates 9 and 10 thus formed
Are bonded by a sealing material 12 via a liquid crystal layer 11 made of, for example, a chiral nematic liquid crystal twisted at an angle of 200 to 270 °. Further, both transparent substrates 9,
A large number of spacers 44 are provided between the spacers 10 in order to keep the thickness of the liquid crystal layer 11 constant.

In the liquid crystal display device 21 in which the semi-transmissive film 42 is disposed as described above, when used as a reflection type (reflection mode), irradiation light by external illumination such as sunlight or a fluorescent lamp is used. Passes through the polarizing plate 36, the phase difference plate 35, and the liquid crystal panel sequentially, but the light incident inside the liquid crystal panel passes through the color filter 17, reaches the semi-transmissive film 42, and Then, the light passes through the liquid crystal panel, passes through the phase difference plate 35 and the polarizing plate 36, and is emitted.

On the other hand, when the liquid crystal display device 21 is set to the transmission mode, the irradiation light of the backlight 39 sequentially passes through the polarizing plate 38, the phase difference plate 37, and the transparent substrate 10 of the liquid crystal panel, and becomes semi-transmissive. After passing through the film 42, the color filter 1
7 and then through the liquid crystal panel,
5 and the polarizing plate 36 to emit light.

Further, by forming the semi-transmissive film 42 on the transparent substrate 10, in the reflection mode, by increasing the reflectance in particular, a brighter display can be obtained, and in the transmission mode, a high contrast can be obtained. The reflection mode and the transmission mode can be enhanced to the extent that both functions of the reflection mode and the transmission mode can be satisfied.The panel used in the reflection mode can be used in the transmission mode under the same conditions. In each case, stable and vivid color display was achieved.

The semi-transmissive film 4 is formed on the inner surface of the transparent substrate 10.
2, the transparent substrate 1 is used even in the reflection mode.
0, so that the phenomenon that the display looks double due to the transparent substrate 10 does not occur. Further, since the incident light and the reflected light pass through the same pixel, a decrease in brightness and color purity is prevented.

The semi-transmissive film 42 is made of a metal thin film such as aluminum, chromium, SUS, or Ag. However, as the film thickness increases, the light transmittance decreases and the light reflectivity increases. The thickness of such a metal thin film has a different light absorption coefficient depending on the type of metal, and is also determined by which of the applications, the reflection mode and the transmission mode, requires improved performance. , Usually 50-500 °, preferably 100-400 °
It is good to Thereby, characteristics as a transflective liquid crystal display device having a reflectivity of 30 to 70% and a transmittance of 5 to 50% can be obtained.

For example, when the semi-transmissive film 42 is formed of an aluminum metal thin film having a thickness of 250 °, the reflectivity becomes 6
5% and the transmittance is 15%.

In the case of the liquid crystal display device 21 having the above structure, when the semi-transmissive film 42 is specular, a light scattering plate between the transparent substrate 9 of the liquid crystal panel and the retardation plate 35 is further provided. A body may be formed. For example, IDS (Internal Diffusin) manufactured by Dai Nippon Printing Co., Ltd.
g Sheet), which contains beads and the like in the resin. In addition, light scattering irregularities may be provided on the surface of the flat plate.

By providing such a light scattering film between the liquid crystal panel and the phase difference plate 35, when used in the reflection mode, the reflected light reflected by the semi-transmissive film 42 becomes positive by the light scattering film. The light is also scattered in directions other than the reflection direction, thereby increasing the viewing angle of the image display and widening the recognition area of the image display.

The present invention is not limited to the above embodiment, and various changes and improvements may be made without departing from the scope of the present invention. For example, in the above-described embodiment, the description has been made with the STN type simple matrix type color liquid crystal display device. However, in addition, a bistable type simple matrix type color and monochrome liquid crystal display device, and a monochrome type STN type simple matrix device are described. The same operation and effect can be obtained even in the liquid crystal display device of the above or the TN type simple matrix type liquid crystal display device.

Although the portable terminal is exemplified as the device provided with the liquid crystal display device of the present invention, the present invention is also applicable to various devices using the liquid crystal display device as a display device. For example, it may be used as a display board of various display devices such as a sewing machine, a stereo, a musical instrument, a video, an ATM, a copier and a facsimile, a station, a restaurant, and a display panel in a factory.
