Abstract
When electrodes in two-layer composition, provided with a color filter in the inside thereof, are provided on the inner surface of a liquid crystal cell board, it is aimed to prevent creation of faulty connections in contact holes and to transmit a driving voltage normally even if faulty connections may occur. A first-layer transparent electrode 1a is formed on the board, then resist is coated so that the contact holes 6 are open on the side surface in one side of the electrode pattern, on which a color filter 3 is formed. After that, said resist is removed and a second-layer transparent electrode 1b is formed in film.
Claims2
A method of manufacturing a color filter on a board composed of liquid crystal cells, said method comprising the steps of:
- applying a first transparent electrode layer having a side on said board;
- coating a photoresist on portions of said first transparent layer so that at least one portion of said photoresist is in contact with the side of the first electrode layer;
- layering a color-filter on said first electrode layer and around said portions of said photoresist;
- removing said photoresist to create at least one contact hole open to the side of said first electrode layer;
- and
- applying a second transparent electrode layer on said color filter so that said contact hole electrically connects said second electrode layer to said first electrode layer.
The method of manufacturing a color filter on a board as described in claim 3, further comprising the step of forming electrode connectors, 5 .mu.m or more each, continuously between each pixel on said color filter.
