Abstract

In an array substrate and an LCD apparatus having the same, the array substrate includes a signal line, a first insulating layer formed on the signal line, and a pixel electrode formed on the first insulating layer and overlapped with the signal line. The pixel electrode is electrically connected with the signal line so as to discharge a signal through the signal line. A second insulating layer is disposed between the pixel electrode and the first insulating layer, and includes an opening formed in an overlapped area of the pixel electrode and the signal line so as to partially expose the first insulating layer. Thus, the LCD apparatus may have an enhanced display quality.

Claims (12)

1. A method of repairing an array substrate including a base substrate, a signal line, a first insulating layer, a second insulating layer, and a pixel electrode, the method comprising:

irradiating a laser onto a protruding portion of the pixel electrode to electrically connect the pixel electrode to the signal line,

wherein the signal line is formed on the base substrate, the first insulating layer is formed on the base substrate having the signal line formed thereon, the second insulating layer is formed on the first insulating layer, the second insulating layer having an opening that exposes the first insulating layer and the pixel electrode is formed on the second insulating layer, and

wherein the protruding portion of the pixel electrode overlaps the signal line in the opening.

2. The method of claim 1 , wherein the pixel electrode comprises:

a transmissive electrode; and

a reflective electrode that is formed on the transmissive electrode, and that has a transmissive window through which the transmissive electrode is exposed.

3. The method of claim 1 , wherein the second insulating layer comprises a thickness in a reflective area on which the reflective electrode is formed that is thicker than a thickness in a transmissive area at which the transmissive window is formed.

4. The method of claim 3 , wherein a first distance between the transmissive electrode and the common electrode is larger than a second distance between the reflective electrode and the common electrode.

5. The method of claim 3 , wherein the signal line is overlapped with the transmissive electrode in the transmissive area.

6. A method of repairing an array substrate including a base substrate, a gate line, a source line crossing the gate line, an insulating layer formed on the gate line and a pixel electrode partially overlapping with the gate line, the method comprising:

irradiating a laser onto a portion of the pixel electrode, which overlaps with the gate line, to electrically connect the pixel electrode to the gate line so that a gate signal is provided to the pixel electrode during operation of the array substrate.
