Abstract

A thin film transistor array panel includes: a substrate; a gate line and a storage electrode that are disposed on the substrate; a data line that crosses the gate line and storage electrode line; a thin film transistor that is connected with the gate line and data line; and a pixel electrode that is connected to the thin film transistor. The storage electrode includes a first storage electrode that is parallel to the gate line, second storage electrodes that extend on opposing sides of the data line from the first storage electrode, a connection part that crosses the data line and connects pairs of the second storage electrodes, and a connection bridge that crosses the gate line and connects a second storage electrode to a second storage electrode of an adjacent pixel.

Claims (19)

1. A thin film transistor array panel, comprising:

a substrate comprising pixel areas that are arranged in columns and rows;

gate lines that extend along each of the rows;

data lines that extend along the columns;

thin film transistors that are disposed in the pixel areas and are connected to the gate lines and the data lines;

pixel electrodes that are disposed in the pixel areas and are connected to the thin film transistors;

the storage electrodes comprising:

first storage electrodes that extend along the gate lines;

second storage electrodes that extend from the first storage electrodes and are paired along opposing sides of each data line; and

connection parts that extend across the data lines and directly connect the second storage electrodes of each pair; and

connection bridges that extend across the gate lines and connect the second storage electrodes of adjacent rows.

2. The thin film transistor array panel of claim 1 , wherein the second storage electrodes each comprise a fixed end that is connected to one of the first storage electrodes and a free end that is not connected to one of the first storage electrodes.

3. The thin film transistor array panel of claim 2 , wherein the second storage electrodes each comprise a first bent part connected to the fixed end, a second bent part connected to the free end, and a linear part that extends between the first bent part and the second bent part.

4. The thin film transistor array panel of claim 3 , wherein the connection parts are generally Y-shaped or V-shaped.

5. The thin film transistor array panel of claim 4 , wherein the second storage electrodes of each pair are bilaterally symmetrical with respect to the corresponding data line.

6. The thin film transistor array panel of claim 2 , wherein the connection bridges connect the fixed ends of the second storage electrodes of the rows to the free ends of the second storage electrodes of adjacent rows.

7. The thin film transistor array panel of claim 6 , wherein the connection bridges and the pixel electrodes comprise the same type of material and are formed directly on the same layer.

8. The thin film transistor array panel of claim 1 , wherein the pixel electrode and thin film transistor of adjacent pixel areas in the same row are inversely symmetrical with respect to the corresponding data line.

9. A thin film transistor array panel including the thin film transistor array panel of claim 2 , wherein each of the paired second electrodes are connected by two of the connection parts.
