Abstract

A display substrate includes a substrate having a first region and a second region, a conductive pattern is provided in the first region of the substrate and includes a first conductive pattern and a second conductive pattern, the first conductive pattern has a gate electrode and a source electrode, the second conductive pattern has a source electrode and a drain electrode, an insulation layer pattern is positioned on the conductive pattern and exposes an outer sidewall of the conductive pattern, an organic layer is provided in the first region and the second region of the substrate and covers the insulation layer pattern, and a pixel electrode is provided on the organic layer and is electrically connected to the drain electrode through a contact hole in the organic layer.

First claim

What is claimed is:

1. A display substrate comprising:
a substrate having a first region and a second region;
a conductive pattern in the first region of the substrate and comprising a first conductive pattern and a second conductive pattern, the first conductive pattern comprising a gate electrode and a gate line, the second conductive pattern comprising a source electrode and a drain electrode;
a gate insulation layer pattern covering the gate electrode and the gate line;
an insulation layer pattern covering the gate electrode and the gate line and configured to expose an outer sidewall of the second conductive pattern, the gate insulating layer pattern being between the gate line and the insulation layer pattern;
an organic layer in the first region and the second region of the substrate covering the insulation layer pattern; and
a pixel electrode on the organic layer and electrically connected to the drain electrode through a contact hole of the organic layer.

2. The display substrate of claim 1 , wherein the insulation layer pattern comprises silicon nitride or silicon oxide.

3. The display substrate of claim 1 , wherein the organic layer contacts the outer sidewall of the second conductive pattern.

4. The display substrate of claim 1 , wherein the organic layer contacts the substrate at the second region thereof.

5. The display substrate of claim 1 , wherein the substrate has a first refractive index, the organic layer has a second refractive index greater than the first refractive index, and the pixel electrode has a third refractive index greater than the first refractive index.

6. The display substrate of claim 5 , wherein the third refractive index is greater than the second refractive index.

7. The display substrate of claim 1 ,
wherein the source electrode and the drain electrode are spaced apart from each other on the gate insulation layer pattern.

8. The display substrate of claim 1 , wherein the organic layer comprises a color filter layer.

9. The display substrate of claim 8 , further comprising a capping layer covering the organic layer.

10. The display substrate of claim 1 , wherein the organic layer comprises a siloxane organic layer or an acrylic organic layer.
