    Abstract: PURPOSE: To avert recognition as a defect by packing a negative type photosensitive resin contg. pigments of the same color into the defective part of colored pixels. CONSTITUTION: A black matrix 2 is formed of chromium on a transparent substrate 4 and, thereafter, the pigments of red, green and blue are successively applied thereon to form color filters by exposing, developing and post baking stages. CRY is again applied on the colored pixels by spin coating in order to repair the defect 3 of a red image 1R generated at this time and is developed by a prescribed developer after exposure 6. In such a case, only the photosensitive resin of the defective part is polymerized under a exposure energy condition and a material 5 for repair may be packed into the defective part 3. ITO transparent electrodes are thereafter formed by sputtering and the transparent substrate is combined with a TFT substrate, by which a liquid crystal is assembled. The negative type photosensitive resin of the same color is packed in the defective part if the defects is single color and the resin of gray is packed therein when the defect is several colors, by which the display is improved.

    Abstract: PURPOSE:To provide the function of a color filter having excellent color purity and a uniform liquid crystal orienting function to one film by forming the org. film of the liquid crystal display device of polyimide having a specific repeating unit. CONSTITUTION:This device has the film commonly having the function of an orienting layer which regulates the orientation of liquid crystal molecules and the function of the color filter. The film has the repeating unit expressed by any one among the formula I, II and III. Namely, the polyimide is obtd. by the condensation polymn. reaction of a diamine component and acid anhydride component. More specifically, both are subjected to a ring opening polyaddition reaction in a solvent to form a polyimide precursor. A dye is dispersed into this precursor and the dispersion is applied on a glass substrate for a liquid crystal display element and is dried and heat treated. The org. film which commonly has the functions of the color filter having the repeating unit and the liquid crystal orienting film is formed in this way.

    Abstract: PURPOSE:To form a light shielding layer which eliminates the damages on picture element electrodes and other electrodes at the time of production, withstands a high temp., is thin in film thickness and can shield light in the regions between the picture elements with good positional accuracy by forming the light shielding layer consisting of an acrylic resin having a crosslinking structure. CONSTITUTION:The light shielding layer 10 consisting of the acrylic resin having the crosslinking structure dispersed with carbon black is formed between the picture element electrodes 6 on a glass substrate 2 and on TFTs 8. The acrylic resin having the crosslinking structure can be formed by exposing, developing and etching a negative photoresist consisting of the acrylic resin and a photopolymn. initiator. The light shielding layer 10 which is increased in the thickness of the layer, withstands the high temp., and does not damage the picture element electrodes 6 and the other electrodes at the time of production is obtd. in this way.

    Abstract: The disclosure describes the provisions of a liquid crystal display device which does not require highly accurate alignment of two transparent substrates, precludes damage to picture element electrodes during manufacture and is resistant to high temperatures. The device also includes a thin light shielding layer which shields the regions between picture element electrodes from light. The light shielding layer is formed by an acrylic resin With a cross-linked structure in which carbon black particles are dispersed, between a plurality of picture element electrodes formed on a transparent substrate.

    Abstract: A method is provided for correcting defects in colour filters containing coloured pixels. The method comprises: applying a negative type photosensitive resin, in which a pigment is dispersed, to the colour pixels that have defects; exposing the photosensitive resin to light through the coloured pixels having the defect; and developing the exposed photosensitive resin. If the defects occur in just one colour of pixel then the pigment dispersed in the resin is of that particular colour. However, if the defects spread over several pixels of different colours then a grey pigment is dispersed in the resin.
