Abstract

PURPOSE:To avert the inconvenience, such as color slurring, of color filters at the time of forming an insulating film and to improve color display quality by interposing the insulating film consisting of an org. high polymer between the color filter of a lower layer and 1st electrodes of an upper layer of a 1st substrate of the color liquid crystal display device. CONSTITUTION:The transparent insulating film consisting of the org. high polymer is provided between the color filters 11 and the electrodes Xn, Yn. Namely, the transparent insulating film of the org. high polymer is used as a protective film for the color filters 11 of the lower layer thereof. The slurring by parallax is minimized in this way without entailing the distortion and color slurring of the colored color filters of the lower layer; in addition, the flatness for forming the electrodes of the upper layer is assured and the color display quality is improved.

Although it is possible to display a color image in this way, a thickness of approximately 1 ffll is formed between the transparent electrode Xn and the color polarizing element (7).
Due to the presence of the glass substrate 1 (2), a problem occurs due to isoparallax where the displayed color overlaps with the adjacent color when viewed from an oblique direction with respect to the display surface, making it impossible to obtain the desired color.

In order to solve this problem, it has been proposed to place a color polarizing element (7) on the inner surface of the glass substrate (2). Since it is formed by dyeing the color polarizing element (7), it has the disadvantage that if it is applied to the inner surface of the substrate (2), it will cause distortion and the relative position of the transparent electrode Xn will shift. However, there is a problem in that the material must be dyed into the polymeric material that serves as the base material, and the number of materials is limited.

To explain its operation, in the electric field application part, the liquid crystal molecules (6') (6') are aligned in the direction of the electric field, so the light that has passed through the polarizing plate <10> and becomes linearly polarized light remains as it is in the liquid crystal (
6>, is colored by a color filter (11>), and exits to the display side via a polarizing plate (16).Therefore, red,
A color image is formed using the primary colors of green and blue or their composite color. On the other hand, in the part where no electric field is applied, the linearly polarized light from the polarizing plate 10 is divided into liquid crystal molecules (6') (6'),
Since the light is rotated by 90 degrees at The color becomes black. In this case, when a black dichroic dye is mixed into the liquid crystal (6), the black background becomes even darker. In this way, a color image is displayed on the black background.

As described above, according to the present invention, only several hundred insulating films are interposed between the color filter and the transparent electrode, so there is no risk of parallax occurring between the two, and the transparent electrode facing Since there is no substance other than the liquid crystal between them, the entire applied electric field is applied to the liquid crystal, and the steep threshold voltage for driving the liquid crystal is maintained. Furthermore, the color filter can be formed using a conventionally well-known printing technique that applies oil-based color ink to the inner surface of a glass substrate, so a highly accurate color pattern can be formed with a simple technique.
