Abstract

A display device includes: a gate electrode, a gate line, and data lines on a substrate, the data lines in a same layer as the gate line; a gate insulating layer on the gate line; a semiconductor member on the gate insulating layer; an etch stopper layer on the semiconductor member and the gate insulating layer; a first passivation layer on the etch stopper layer; a source electrode on the first passivation layer and the etch stopper layer and connected to the data lines; a drain electrode on the etch stopper layer; a common electrode on the first passivation layer and separated from the source electrode and the drain electrode; a second passivation layer on the source electrode, the drain electrode and the common electrode; and a pixel electrode on the second passivation layer and connected to the drain electrode.

First claim

What is claimed is:

1. A display device, comprising:
a substrate;
a gate electrode and a gate line disposed on the substrate;
data lines disposed on the substrate in a same layer as the gate line, and electrically separated from the gate line;
a gate insulating layer disposed on the gate line, the gate electrode, and the data lines;
a semiconductor member disposed on the gate insulating layer;
an etch stopper layer disposed on the semiconductor member and the gate insulating layer;
a first passivation layer disposed on the etch stopper layer;
a source electrode disposed directly on top of the first passivation layer and the etch stopper layer, the source electrode electrically connected to the data lines;
a drain electrode disposed directly on top of the etch stopper layer and electrically separated from the source electrode;
a common electrode disposed directly on the first passivation layer and electrically separated from the source electrode and the drain electrode;
a second passivation layer disposed directly on the source electrode, the drain electrode and the common electrode; and
a pixel electrode disposed on the second passivation layer and electrically connected to the drain electrode.

2. The display device of claim 1 , wherein the first passivation layer comprises an organic material.

3. The display device of claim 1 , wherein the semiconductor member comprises a metal oxide.
