Abstract: PURPOSE: To provide the liquid crystal display device which is improved the light shielding capability in a frame area and preventing capability against electrostatic trouble without increasing manufacture processes as to the improvement of the frame area of the liquid crystal display panel of the liquid crystal display device. CONSTITUTION: A light shield layer 12 is formed in the frame area 1 on a TFT array substrate 3. The edge part of the light shield layer 12 has an overlap area 14 which overlaps with respective edge parts of data lines 10 as metallic layers and the surface of the TFT array substrate 3 by a specific overlap quantity (d) when viewed vertically. An insulating layer 16 is formed on the light shield layer 12 and TFT array substrate 3. On the insulating layer 16, a semiconductor layer 18 is formed. The data lines 10 are wired on the semiconductor layer 18.

Abstract: PURPOSE: To improve the quality of a display image deteriorated by a reverse tilt by constituting a light shielding layer formed on the edge of an aperture arranged on the upstream of a rubbing direction of a specific thin light shielding layer and a specific thick light shielding layer. CONSTITUTION: A light shielding layer on the edge of a display area on the upstream of the rubbing direction is formed on the peripheral edge of a display electrode 3 and constituted of a thin light shielding layer 5 for restricting the edge 6 of an aperture and a thick black photoresist layer, i.e., a black photosensitive organic material layer 4 positioning its edge 7 on the layer 5. An edge 6 is separated from the edge 7 by a distance L and the layer 5 should be formed on the edge of the aperture existing on the upstream of the rubbing direction in order to solve a reverse tilt. Since it is preferable that all liquid crystal display cells have the same numerical aperture, the formation of a thin light shielding layer 5 on the downstream of the rubbing direction is also preferable. The numerical aperture means the rate of a light passing area to the edge area of the liquid crystal display cell.

Abstract: PURPOSE: To manufacture a color filter that is provided with general performance as a color filter and enables a high contrast display by using a reaction product of a binder polymer and a reactive dye with each other as a component of the color filter. CONSTITUTION: This color filter has at least one color layer formed from a photosensitive composition contg. a reaction product of a binder polymer and a reactive dye with each other. The binder polymer is a linear organic polymer which contains functional groups such as hydrogen radicals or amino or amide groups in its side chains in an amount sufficient to subject the reactive dye to addition reaction with the binder and is compatible with its monomer (s). For example, a homopolymer or copolymer of hydroxyethyl acrylate, aminoethyl acrylate or acrylamide, or a partially esterified compound of an acid anhydride polymer such as maleic anhydride copolymer or itaconic anhydride copolymer with glycol or aminoglycol, or the like, is useful as this binder polymer. The color filter is most appropriately used for a TFF-LCD (thin film transistor liquid crystal device) which is particularly required to provide a high contrast display and has a gradation display function.
