Abstract
The invention is for a process for manufacturing a liquid crystal display element for use in a color display using resist materials. The process comprises forming a transparent conductive film on one side of a transparent substrate; patterning the transparent conductive film by coating with a colored positive resist followed by exposure and development, coating a black-colored negative resist onto the transparent film; forming black stripes by subjecting the negative resist to exposure from the back side of the transparent substrate and development of the negative resist.
Claims3
A process for manufacturing a liquid crystal display element for a color display which comprises:
- forming a transparent conductive film on one side of a transparent substrate;
- patterning the transparent conductive film by coating a colored light-sensitive resist on said transparent conductive film and then exposing and developing said light sensitive resist;
- thermosetting said light-sensitive resist at a temperature of 130° C. up to 170° C.;
- coating a black-colored negative light-sensitive resist on said patterned transparent conductive film without removal of the positive light-sensitive resist remaining following patterning;
- forming black stripes between transparent conductive film by subjecting the negative light-sensitive resist to exposure from the back side of the transparent substrate followed by development of said negative light-sensitive resist;
- removal of the positive light-sensitive resist remaining on the transparent conductive film.
A process for manufacturing a liquid crystal display element for a color display which comprises the steps of:
- forming a transparent conductive film on one side of a transparent substrate;
- without exposure from a back side, patterning the transparent conductive film by coating a positive light-sensitive resist onto the transparent conductive film and then exposing and developing said resist to yield a coating having valleys therein;
- injecting black-colored resin into the valleys between the positive light-sensitive resist;
- forming black stripes on said transparent conductive film by curing the black-colored resin;
- and
- removing the positive light-sensitive resist remaining on the transparent conductive film.
