Abstract
A thin film transistor substrate includes a color filter layer and a gate line. The color filter layer has a reverse taper shape, which is used to pattern the gate line without a separate mask. Thus, the total number of masks used to manufacture the thin film transistor substrate can be reduced, thereby reducing the manufacturing cost and improving the productivity.
Claims11
A thin film transistor substrate comprising:
- a base substrate including a pixel area having a switching area, a first line area adjacent to the pixel area, and a second line area adjacent to the pixel area and crossing the first line area;
- a color filter arranged in the pixel area except the switching area and in the second line area and having a reverse taper shape;
- a gate line arranged in the first line area and spaced apart from the color filter;
- a data line overlying the color filter in the second line area;
- a thin film transistor arranged in the switching area and electrically connected to the gate line and the data line;
- and
- a pixel electrode overlying the color filter and electrically connected to the thin film transistor.
