Abstract

Abstract A color filter substrate for a liquid crystal display LCD of which a bad adhesion in a pattern terminal is reduced and an electrode pattern can be easily distinguished, is disclosed. Black matrixes and an indium tin oxide are formed on a glass substrate by using chromium and color filter layers having red, green and blue dyes are formed. A protective film and an ITO transparent electrode layer are deposited on the black matrix and the colors filter layers to be overlapped on a part of each pattern terminal. Thus, a liquid crystal display element can be realized such that the adhesive strength of the ITO can be improved. Also, as the pattern terminal has chromium, a tape automated bonding integrated circuit can be advantageously distinguished at the following process step of mounting it, making the automation of process possible and improving the productivity.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 138 words
A color filter substrate for a liquid crystal display having upper and lower substrate and a liquid crystal therebetween, comprising; (a) a plurality of black matrixes formed at a predetermined interval on a glass substrate; (b) pattern terminals formed at the same height as those of the black matrixes on both end of the substrate; (c) a plurality of color filter layers having red, green and blue dyes sequentially disposed between the black matrix and the pattern terminal, and the black matrix; (d) a protective film formed on the black matrix, the color filter layers, and a part of each pattern terminal;and (e) a transparent electrode layer formed on the protective film, and also formed on each part of said pattern terminal extending from the protective film and so each part of the pattern terminal can be exposed.
Claim 2
Dependent Claim 138 words
A color filter substrate for a liquid crystal display having upper and lower substrate and a liquid crystal therebetween, comprising; (a) a plurality of black matrixes formed at a predetermined interval on a glass substrate; (b) pattern terminals formed at the same height as those of the black matrixes on both end of the substrate; (c) a plurality of color filter layers having red, green and blue dyes sequentially disposed between the black matrix and the pattern terminal, and the black matrix; (d) a protective film formed on the black matrix, the color filter layers, and a part of each pattern terminal;and (e) a transparent electrode layer formed on the protective film, and also formed on each part of said pattern terminal extending from the protective film and so each part of the pattern terminal can be exposed.
Claim 3
Dependent Claim 24 words
The color filter substrate for a liquid crystal display as claimed in claim 1, wherein the black matrix and the pattern terminals comprises chromium.
