Abstract

A display device includes: an insulating substrate comprising a first region and a second region; a thin-film transistor (TFT) formed on the first region comprising a gate electrode, a source electrode, and a drain electrode; and a storage capacitor formed on the second region, wherein the storage capacitor comprises a first electrode, a second electrode and a first interlayer insulating film, where the first and second electrodes face each other and are made of a transparent conductive material, wherein the interlayer insulating film is interposed between the first electrode and the second electrode, and wherein the first electrode is formed on the entire surface of the first substrate as one body and receives a common voltage, and the second electrode is electrically connected to the drain electrode.

Claims (10)

1. A display device comprising:

an insulating substrate comprising a first region and a second region;

a TFT formed on the first region and comprising a gate electrode, a source electrode, and a drain electrode;

a storage capacitor formed on the second region and comprising a first electrode, a second electrode formed on the first electrode, and a first interlayer insulating film formed between the first electrode and the second electrode; and

a pixel electrode formed on the insulating substrate,

wherein the first electrode and the second electrode comprise a transparent conductive material, the pixel electrode is electrically connected to the first electrode by a contact hole which penetrates the second electrode, the first electrode is electrically connected to the drain electrode, and a common voltage is applied to the second electrode.

2. The display device of claim 1 , further comprising a connecting electrode formed between the pixel electrode and the first electrode.

3. The display device of claim 2 , wherein the connecting electrode comprises the same material as the drain electrode of the TFT and is separated from the drain electrode.

4. The display device of claim 2 , wherein the first interlayer insulating film comprises SiNx.

5. The display device of claim 1 , wherein the first electrode is formed on the majority of the entire surface of the insulating substrate as one body.
