Abstract:
1. A method for manufacturing a reflection type liquid crystal display, comprising: forming plural scanning lines and plural signal lines crossing said scanning lines on an insulating substrate; forming a switching element in each of picture element regions divided by said scanning lines and said signal lines; forming an interlayer insulating film having appropriate unevenness of an inseparable pattern in the picture element region and having a contact hole of a separable pattern on a drain electrode of said switching element by plainly applying a photosensitive insulating resin on said substrate so as to dissolve difference in level caused by said scanning lines, said signal lines, and said switching element, and conducting exposure and development while changing an amount of exposure; and forming a reflex picture element electrode having unevenness due to said interlayer insulating film at a position conforming to each of the picture element regions and which is electrically connected to said switching element through said contact hole, by patterning after forming a high reflex film on said interlayer insulating film, wherein in the process of forming the interlayer insulating film, a mask is used in exposing the insulating resin and has a shading material comprised of at least two layers, the at least two layers including an ultraviolet filter layer for cutting ultraviolet rays at a predetermined value of 20 to 80% in a base material, and said ultraviolet filter layer is laid in a mask pattern opening portion located conforming to the picture element region, and the exposure for forming unevenness on the interlayer insulation film is conducted only from a front side.
