Abstract

A thin film transistor (TFT) array substrate includes a TFT including an active layer, a gate electrode, a source electrode, a drain electrode, a first gate insulating layer and a second gate insulating layer formed between the active layer and the gate electrode, and an interlayer insulating layer formed between the gate electrode and the source electrode and the drain electrode; a pixel electrode formed in an opening of the interlayer insulating layer, the pixel electrode including transparent conductive oxide; a translucent electrode formed in a region corresponding to the pixel electrode, between the first gate insulating layer and the second gate insulating layer; and a capacitor including a lower electrode formed from the same layer as the active layer, and an upper electrode formed from the same layer as the translucent electrode.

First claim

What is claimed is:

1. A thin film transistor (TFT) array substrate comprising:
a TFT comprising an active layer, a gate electrode, a source electrode, a drain electrode, a first gate insulating layer and a second gate insulating layer formed between the active layer and the gate electrode, and an interlayer insulating layer formed between the gate electrode and the source electrode and between the gate electrode and the drain electrode;
a pixel electrode formed in an opening of…
