Abstract

A display device having a gate line on a first substrate, a gate insulating layer covering the gate line, a semiconductor layer on the gate insulating layer, a data line intersecting the gate line and including a source electrode and a drain electrode facing the source electrode on the semiconductor layer, a connection assistant separated from the data line, a passivation layer covering the data line and including contact holes exposing the connection assistant and a pixel electrode, including a plurality of sub-pixel electrodes, and formed on the passivation layer. The sub-pixel electrodes are electrically connected to each other through the connection assistant and at least one of the sub-pixel electrodes is electrically connected to the drain electrode. The connection assistant is connected to facing edges of adjacent sub-pixel electrodes and is disposed at about ¼ the distance from the end of the left or the right side of the sub-pixel electrode.

Claims (22)

1 . A display device, comprising:

a first substrate;

a second substrate facing the first substrate;

a gate line disposed on the first substrate;

a data line intersecting the gate line;

a thin film transistor arranged near a crossing of the gate line and the data line;

a gate electrode of the thin film transistor being connected to the gate line, a source electrode of the thin film transistor being connected to the data line, and a drain electrode of the thin film transistor being connected to a pixel electrode to apply a voltage to a liquid crystal layer;

a passivation layer disposed on the data line, the passivation layer comprising a contact hole exposing the drain electrode in an aperture area;

a pixel electrode disposed on the passivation layer and connected to the drain electrode, the pixel electrode comprising a plurality of sub-pixel electrodes and a connection assistant connecting the sub-pixel electrodes to each other;

a plurality of apertures respectively formed on the center position of the sub-pixel electrodes; and

a transparent storage electrode charge coupled with the pixel electrode.

2 . The display device of claim 1 , wherein the connection assistant is disposed on a first position or a second position that is shifted from the center of the pixel electrode.

3 . The display device of claim 1 , wherein the first position or the second position is disposed about ¼ the distance from an edge of the sup-pixel electrode.

4 . The display device of claim 1 , wherein the connection assistant is connected to facing edges of adjacent sub-pixel electrodes.

5 . The display device of claim 1 , wherein the connection assistant is formed on the same layer as the pixel electrode.

6 . The display device of claim 1 , wherein the connection assistant is formed on a different layer than the pixel electrode and is connected to the pixel electrode through a contact hole.

7 . The display device of claim 1 , wherein the sub-pixel electrodes each have a substantially rectangular shape with rounded corners.

8 . The display device of claim 1 , wherein the sub-pixel electrodes comprise a transmission electrode.

9 . The display device of claim 1 , wherein at least one sub-pixel electrode comprises a reflection electrode.

10 . The display device of claim 1 , wherein the apertures are formed on the sub-pixel electrodes of the first substrate.

11 . The display device of claim 1 , wherein the apertures are formed on a common electrode of the second substrate.

12 . The display device of claim 1 , wherein the apertures have a circular shape.
