Abstract

An liquid crystal display device includes a source line between first and second drain lines, a first and second gate lines between the first drain line and the source line and between the second drain line and the source line, a plurality of first and second drain electrodes extending from the first and second drain lines, and a plurality of first and second source electrodes extending in first and second directions from the source line, wherein the plurality of first source electrodes are alternated with the plurality of first drain electrodes on the first gate line, and the plurality of second source electrodes are alternated with the plurality of second drain electrodes on the second gate line.

Claims (19)

1. An liquid crystal display (LCD) device comprising:

a liquid crystal panel for displaying an image; and

a driving unit mounted on the liquid crystal panel and having a switching element for controlling an output, the switching element comprises:

first and second drain lines;

a source line between the first and second drain lines;

first and second gate lines between the first drain line and the source line and between the second drain line and the source line;

a plurality of first and second drain electrodes extending from the first and second drain lines; and

a plurality of first and second source electrodes extending in first and second directions from the source line,

wherein the plurality of first source electrodes are alternated with the plurality of first drain electrodes on the first gate line, and the plurality of second source electrodes are alternated with the plurality of second drain electrodes on the second gate line.

2. The LCD device according to claim 1 , wherein the source line is arranged parallel with the first and second drain lines.

3. The LCD device according to claim 1 , wherein the first and second gate lines are arranged parallel with the first and second drain lines.

4. The LCD device according to claim 1 , wherein the first drain electrodes are arranged perpendicular to the first gate line.

5. The LCD device according to claim 1 , wherein the second drain electrodes are arranged perpendicular to the second gate line.

6. The LCD device according to claim 1 , wherein the first and second source electrodes are arranged interdigitally extending in the first and second directions from the source line.

7. The LCD device according to claim 1 , wherein one of the first source electrodes is commonly used in a plurality of thin film transistors formed by the one source electrode, the first drain electrodes adjacently disposed above and below the one source electrode, and the first gate line.

8. The LCD device according to claim 1 , wherein one of the second source electrodes is commonly used in a plurality of thin film transistors formed by the one source electrode, the second drain electrodes adjacently disposed above and below the one source electrode, and the second gate line.

9. The LCD device according to claim 1 , wherein one of the first drain electrodes is commonly used in a plurality of thin film transistors formed by the one drain electrode, the first source electrodes adjacently disposed above and below the one drain electrode, and the first gate line.

10. The LCD device according to claim 1 , wherein one of the second drain electrodes is commonly used in a plurality of thin film transistors formed by the one drain electrode, the second source electrodes adjacently disposed above and below the one drain electrode, and the second gate line.

11. The LCD device according to claim 1 , wherein the switching element comprises a plurality of thin film transistors connected in parallel.
