Method of manufacturing a color liquid crystal panel
View Patent ↗Within a reflective display section R, a part of a light that reaches a reflective electrode through a color filter exits to the outside through slits and a part of a light that reaches the reflective electrode through the slits exits to the outside through the color filter. In addition, a light reaching the reflective electrode through the color filter and exiting to the outside through the color filter, and a light having no opportunity to pass through the slits also can be observed. Therefore, a mean film thickness of color filter through which all lights pass during the time in which they travel the associated distance after they are inputted to the inside until they are outputted to the outside becomes nearly equal to that could be observed in the transmissive section T.
1. A method of manufacturing a color liquid crystal panel, wherein the color liquid crystal panel comprises: a transparent substrate; an insulation film formed on the transparent substrate to have a convex-concave surface and a contact hole; and a reflective electrode formed on the insulation film, the method comprising the steps of:
using a photomask of a lamination structure comprising a semi-transparent film and a light incidence preventing film, wherein the semi-transparent film has an opening corresponding to the contact hole and the light incidence preventing film has an opening corresponding to a recess portion of the insulation film and an opening corresponding to the contact hole and an periphery thereof,
exposing a raw material film of the insulation film, forming an exposed portion whose thickness is equal to that of the raw material film of the insulation film by means of exposure to light transmitted through the openings formed on the light incidence preventing film and the opening formed on the semi-transparent film, and forming an exposed portion whose thickness is smaller than that of the raw material film of the insulation film by means of exposure to light transmitted through the openings formed on the light incidence preventing film and the semi-transparent film; and
removing the exposed portions formed on the raw material film of the insulation film, baking the raw material film of the insulation film, and thereby forming the contact hole on the recess portion of the insulation film and the convex-concave surface on the insulation film.
2. The method of claim 1 , wherein
a projecting portion of the insulation film is formed within a pixel of the color liquid crystal panel, a projecting portion is formed in a boundary with an adjacent pixel, and a width of the projecting portion within the pixel is substantially same as a width of the projecting portion in the boundary.
