Abstract

A panel 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 semiconductor layer 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 connected to the connection assistant through the contact holes, 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.

Claims (28)

1. A panel, comprising:

a first substrate;

a gate line formed on the first substrate;

a gate insulating layer covering the gate line;

a semiconductor layer formed on the gate insulating layer;

a data line intersecting the gate line and including a source electrode formed on the semiconductor layer;

a drain electrode formed on the semiconductor layer and facing the source electrode;

a connection assistant separated from the data line;

a passivation layer covering the semiconductor layer 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, wherein the sub-pixel electrodes of one pixel are respectively connected to the connection assistant through the contact holes, and

wherein the sub-pixel electrodes of the one pixel 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.

2. The panel of claim 1 , wherein the sub-pixel electrodes include a transmission electrode.

3. The panel of claim 1 , wherein at least one of the sub-pixel electrodes includes a reflection electrode.

4. The panel of claim 1 , wherein the sub-pixel electrodes have a substantially rectangular shape with rounded corners.

5. The panel of claim 1 , further comprising:

a second substrate facing the first substrate; and

a common electrode formed on the second substrate and including a plurality of cutouts respectively formed substantially on the center of the sub-pixel electrodes.

6. The panel of claim 1 , wherein the cutouts have a circular shape.

7. The panel of claim 1 , wherein the connection assistant is formed on same layer of the panel as the data line.

8. A method of forming a display panel, the method comprising:

forming a gate line, a data line and a drain electrode on a first substrate, the data line intersecting the gate line and the drain electrode facing the data line;

forming a thin film transistor on the first substrate and connected to the gate line and the data line;
