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.
