Color liquid crystal panel, method for manufacturing the same, and color liquid crystal display device employing the same
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 that has a transparent substrate, an insulation film that is on the transparent substrate and that has a convex-concave surface and a contact hole, and a reflective electrode on the insulation film, the method comprising the steps of:
placing a first photomask over a raw material film of the insulation film, the first photomask having first openings corresponding to a closed area, the contact hole and a peripheral portion thereof existing within boundaries of the first openings;
forming first exposed portions of the raw material film using the first photomask, the first exposed portions each having a thickness less than that of the raw material film and a size corresponding to the first openings;
placing a second photomask over the raw material film, the second photomask having a second opening corresponding to the contact hole;
forming a second exposed portion of the raw material film using the second photomask, the second exposed portion having a thickness equal to that of the raw material film and a size corresponding to the second opening;
removing the first and second exposed portions; and
baking the raw material film to form the insulation film with the contact hole.
