Thin film transistor substrate, display apparatus having the same, and manufacturing method thereof

摘要

Each pixel of a thin film transistor substrate includes a base substrate including a pixel display area and a pixel non-display area surrounding the pixel display area, a gate electrode on the base substrate in the pixel non-display area, a first insulating layer which is on the base substrate in the pixel non-display area and covers the gate electrode, a semiconductor layer on the first insulating layer, of which a predetermined portion thereof overlaps the gate electrode, a source electrode and a drain electrode which are spaced apart from each other and on the semiconductor layer, a second insulating layer which is on the first insulating layer and the base substrate and covers the source electrode and the drain electrode, and a pixel electrode on the second insulating layer in the pixel display area.
