Background technology
For the miniaturization of the nearest electronic equipment of correspondence, the trend of low price, the drive IC of STN type (supertwist nematic phase Super-Twisted Nematic) liquid crystal indicator is used by two synthetic a slices.That is, two drive IC that in the past were connected to each transparency electrode of public side and fan-shaped side are focused on a side of panel, these two drive IC are transformed into a drive IC drive.
Fig. 6, Fig. 7 and Fig. 8 represent is in the past liquid crystal indicator.As shown in Figure 6, liquid crystal indicator 100 in the past possesses first substrate 110 that clamping diagram abridged liquid crystal layer is oppositely arranged and second substrate 120 and constitutes, on the face of the liquid crystal face side of first substrate 110, be provided with the diagram abridged transparency electrode (sector electrode) that is used to drive liquid crystal layer, on the face of the liquid crystal face side of second substrate 120, be provided with the diagram abridged transparency electrode (public electrode) that is used to drive liquid crystal layer.And, between each substrate 110,120, the anisotropic conductive encapsulant (anisotropic conductive resin) 140 that comprises conductive particle forms in the form of a ring, because liquid crystal layer is configured in the inboard of this anisotropic conductive encapsulant 140, is the state that is clamped between each substrate 110,120.And the medial region of anisotropic conductive encapsulant 140 disposes fan-shaped click and the public electrode of speaking of just now as effective viewing area D in the D of this effective coverage.
And as shown in Figure 6, on first substrate 110, be not provided with overlappingly with second substrate 120 and expose portion of terminal 110a, on this portion of terminal 110a, drive IC 150 is installed.And then, second extension line 107 that first extension line 106 of the transparency electrode that connects drive IC 150 and fan-shaped side is set on first substrate 110 and is connected the transparency electrode of drive IC 150 and public side.
As shown in Figure 6, till the sector electrode of drive IC 150 beginning crosscut anisotropic conductive encapsulants 140 in effective viewing area D, form first extension line 106.
And between one side of anisotropic conductive encapsulant 140 the part 140a and first substrate 110, form second extension line 107, exist along the 140a prolongation of part on one side.And first, second extension line 106,107 becomes the two-layer structure of the metal wiring on this ITO distribution at ITO distribution and lamination.
In Fig. 7, represented one side part 140a amplification plan view nearby of anisotropic conductive encapsulant 140, in Fig. 8, the sectional view of the A-A line of expression corresponding diagram 6 and Fig. 7.As Fig. 7 and as shown in Figure 8, on the face of liquid crystal layer 130 sides of first substrate 110, colour transition filtering layer 111 and circuit layer 112 sequential laminatings that comprise sector electrode just now.Periphery at colour transition filtering layer 111 forms the light shield layer 111a that prevents light leak.And on the face of liquid crystal layer 130 sides of first substrate 110, form a plurality of public electrodes 125 just now.And these public electrodes 125 ... formed by ITO, on the next door of that anisotropic conductive encapsulant 140, lamination light-proofness metal conducting layer 125a such as Cr ...Because these light-proofness metal conducting layers 125a has reduced public electrode 125 ... whole resistivity.
In addition, the 2nd extension line 107 carries out lamination by ITO line 107a and metal wire 107b and constitutes as previously mentioned, makes the 2nd extension line 107b by metal wire 107b ... all resistivity reduce.
And, as Fig. 7 and as shown in Figure 8, first extension line 107 ... each leading section 107c ... with sector electrode 125 ... each leading section 125c ... be that man-to-man relation overlaps the to each other configuration.The anisotropic conductive encapsulant is between the lap of each leading section 107c, 125c, because the anisotropic conductive encapsulant makes second extension line 107 ... with public electrode 125 ... conduct separately.
But, when the liquid crystal indicator of making in the past, after being coated in anisotropic conductive encapsulant 140 on first substrate 110 annularly by screen printing in advance, lump together with the second substrate card, then, from second substrate, 120 side visual observations, check the situation that is coated with of anisotropic conductive encapsulant 140.
If from second substrate, 120 sides observation anisotropic conductive encapsulant 140 with around the moral, anisotropic conductive encapsulant 140 self is transparent milky, with anisotropic conductive encapsulant 140 stacked second extension lines 107 and public click 125 owing to there is the existence of metal film to look like opaque black.Therefore, suppose that light shield layer 111a is formed into the words of the downside of anisotropic conductive encapsulant 140 always, the colour superimposition of the color of light shield layer 111a and second extension line 107 and public electrode 125 is very difficult from second substrate, 120 sides identification anisotropic conductive encapsulant 140.Therefore, on liquid crystal indicator in the past, the inboard of the anisotropic conductive encapsulant 140 of all having to light shield layer 111a is configured in.
But, as shown in Figure 8, when light shield layer 111a is configured to anisotropic conductive encapsulant 140 inboard, can not cover light through anisotropic conductive encapsulant 140, the part of this light invades in effective viewing area D, produces the problem that display performance is descended.

Secondly, the sectional view of the B-B line of expression corresponding diagram 1 and Fig. 2 among Fig. 3, Fig. 4 are represented one side 40a expansion planimetric map nearby of anisotropic conductive encapsulant 40, and Fig. 5 is the sectional view of the C-C line of corresponding diagram and Fig. 4.
As Fig. 3 and as shown in Figure 5, on the face of liquid crystal layer 30 sides of the 1st substrate 10, sequential laminating colour transition filtering layer 11 and comprise the circuit layer 12 of described just now transparency electrode and oriented film.Periphery formation at colour transition filtering layer 11 prevents the light shield layer 11a that light leak is used.This light shield layer 11a is formed on the periphery of effective viewing area D.And, on the face of 30 of the liquid crystal layers of the 1st substrate 10, form a plurality of described just now transparency electrodes 25.
Secondly and as shown in Figure 5 as Fig. 4, configuration the 2nd extension line 7 between one side of anisotropic conductive encapsulant 40 part 40a and light shield layer 11a, this 2nd extension line 7 continues existence along one side part 40a.The 2nd extension line 7 is made of ITO distribution 7a and metal wiring 7b lamination as described above, since this metal wiring 7b, the 2nd extension line 7 ... whole resistivity decreased.
And, as Fig. 4 and as shown in Figure 5, transparency electrode 25 ... a part and anisotropic conductive encapsulant 40 overlapping, its leading section 25a is configured between anisotropic conductive encapsulant 40 and the 2nd substrate 20.And in the inboard of anisotropic conductive encapsulant 40, lamination the light-proofness metal conducting layer 25b of a part of Cr etc. of transparency electrode 25 ...25b makes transparency electrode 25 by this light-proofness metal conducting layer ... whole resistivity reduces.And, remove 1 light-proofness metal conducting layer 25b in transparency electrode 25 and anisotropic conductive encapsulant 40 overlapping parts, forming non-light shielding part 25c on 25 on the transparency electrode.By this non-light shielding part 25c, when from the 2nd substrate 20 sides observation anisotropic conductive encapsulant 40, can estimate the anisotropic conductive encapsulant 40 of the downside that is positioned at transparency electrode 25.
And, as Fig. 4 and as shown in Figure 5, the 1st extension line 7 ... each leading section 7c ... with transparency electrode 25 ... each leading section 25a ... be to dispose one to one with overlapping each other.Anisotropic conductive encapsulant 40 is between the lap of each leading section 7c, 25a, by these anisotropic conductive encapsulant 40, the 2 extension lines 7 ... with transparency electrode 25 ... conduct respectively.
When making the liquid crystal indicator 1 of present embodiment, on the 1st substrate 10, coat anisotropic conductive encapsulant 40 circlewise in advance with methods such as serigraphys, the 2nd substrate 20 is fitted on the 1st substrate 10, is being coated with state inspection from what the 2nd substrate 20 usefulness sight were observed anisotropic conductive encapsulant 40 then.
Observe the words of anisotropic conductive encapsulant and the situation around it from the 2nd substrate 20 sides, anisotropic conductive encapsulant 40 be formed at light shield layer 11a above, itself appear as transparent milky, and on anisotropic conductive encapsulant 40 stacked the 2nd extension line 7 owing to there is metal film, present opaque black, and then transparency electrode 25 is because the existence of non-light shielding part 25c looks water white transparency.
So, at the light shield layer 11a of black and above the 2nd extension line, can discern milky anisotropic conductive encapsulant 40, during fabrication, can easily carry out visual inspection to anisotropic conductive encapsulant 40.
And, because anisotropic conductive encapsulant 40 is formed on the light shield layer 11a overlappingly, prevent back light to the seeing through of anisotropic conductive encapsulant 40, thus, needn't worry the bleed effective viewing area D of inboard of anisotropic conductive encapsulant 40 of back light.Therefore can improve the display performance of liquid crystal indicator 1.
Liquid crystal indicator dress of the present invention is not limited to infiltration type, owing in the reflection horizon of effective built-in scattered reflection in viewing area, can make reflection-type.Perhaps semipermeability is made in the reflection horizon, such as the reflection horizon of the plate of highly reflective being made the above thickness of 100nm (1000 ), here can peristome be set with regulation aperture opening ratio (, the ratio of small peristome with area 10%～30% being formed like that) such as area for pel spacing.
Such as mentioned above, according to liquid crystal indicator of the present invention, owing to overlap to form the anisotropic conductive encapsulant on light shield layer, the light that sees through the anisotropic conductive encapsulant is owing to light shield layer is blocked, needn't worry to reveal effective viewing area, improve display performance.And, because non-light shielding part is arranged on the lap of described anisotropic conductive encapsulant of transparency electrode with other, even at light shield layer and the overlapping state of anisotropic conductive encapsulant, also can be by non-light shielding part identification anisotropic conductive encapsulant.
