Liquid crystal display device and method for manufacturing the same
First Claim
1. A liquid crystal display device, comprising:
- first and second transparent substrates;
a liquid crystal that is enclosed between said first and second transparent substrates;
a first color filter that is formed on either said first or second transparent substrate;
a light reflective layer that has a plurality of openings and that is formed on said second transparent substrate toward the liquid crystal; and
a second color filter that is formed on said second transparent substrate on the side opposite to said liquid crystal.

Abstract
A liquid crystal display device comprises: first and second transparent substrates; a liquid crystal that is enclosed between the first and second transparent substrates; a first color filter that is formed on either the first or second transparent substrate; a light reflective layer that has a plurality of openings and that is formed on the second transparent substrate toward the liquid crystal; and a second color filter that is formed on the second transparent substrate on the side opposite to the liquid crystal. The second color filter is fabricated by forming a layer of a color photosensitive material such as a photosensitive emulsion and illuminating and coloring this layer by light transmitting through the first color filter using the reflective layer as an exposure mask. As a result, a second color filter, that has a color dot pattern the same as that of the first color filter, is formed by one exposure and developing process.

8. A method for manufacturing a liquid crystal display device, comprising the steps of:
-
forming a reflective layer having a plurality of openings and then a first color filter on a second transparent substrate, sequentially;
applying a color photosensitive material on a surface of said second transparent substrate on the side opposite to that on which said reflective layer is formed;
forming a second color filter that has a color dot matrix pattern same as that of said first color filter by illuminating said color photosensitive material from above said first color filter through the openings of said reflective layer;
disposing a first transparent substrate opposed to the surface of said second transparent substrate on which said first color filter is formed; and
filling a liquid crystal between said first and second transparent substrates. - View Dependent Claims (11, 12)

9. A method for manufacturing a liquid crystal display device, comprising the steps of:
-
forming a reflective layer having a plurality of openings and then a first color filter on a second transparent substrate sequentially;
disposing a first transparent substrate through a sealing member opposite to, and above, a surface of said second transparent substrate on which said reflective layer and first color filter are formed;
applying a color photosensitive material on a surface of said second transparent substrate on the side opposite to that on which said first color filter is formed;
forming a second color filter by illuminating said color photosensitive material from above said first transparent substrate through said first color filter, said openings provided on said reflective layer and said second transparent substrate and coloring the material; and
filling a liquid crystal between said first and second transparent substrates. - View Dependent Claims (13, 14)
