Liquid crystal display
View Patent ↗A thin film transistor array substrate including an insulating substrate, a first metallic pattern formed on the insulating substrate, and an insulating film provided on the first metallic pattern. A semiconductor pattern is provided on the insulating film, and a second metallic pattern is provided on the semiconductor pattern. The second metallic pattern is surrounded by the semiconductor pattern.
1. TFT array substrate for a liquid crystal comprising:
source lines and gate lines which are formed in matrix;
a pixel electrode for applying voltage to a liquid crystal and thin film transistors, said pixel electrode being provided in each of parts in which said source lines are intersected with said gate lines, said pixel electrode being protected by a passivation film;
a gate electrode;
a gate insulating film formed on said gate electrode;
a semiconductor layer film provided on said gate insulating film on a region of said gate electrode, said semiconductor layer being formed in such a manner as to contact with said gate insulating film;
a source electrode, a source line and a drain electrode, each of said source electrode, said source line and said drain electrode including at least two layers comprising a transparent conductive film and a metallic film provided on said transparent conductive layer, said transparent conductive film being formed in such a manner as to partially contact with said semiconductor layer;
wherein said drain electrode is connected with said pixel electrode by said transparent conductive layer per se;
wherein said passivation film, and said metallic film and said passivation film which are located on said light transmitting part of said pixel electrode are removed.
