Abstract

A liquid crystal display (LCD) device and a manufacturing method thereof, capable of preventing vertical crosstalk caused by a deviation of a parasitic capacitance, includes a first pixel electrode formed in a first gray scale region of each subpixel region divided into first and second gray scale regions, and a second pixel electrode formed in the second gray scale region separated from the first pixel electrode and encompassed by the first pixel electrode.

Claims (12)

1. A display device, comprising:

a first pixel electrode receiving a first data signal from a first data line; and

a second pixel electrode receiving a second data signal from a second data line, the second pixel electrode separated from and encompassed by the first pixel electrode in a plan view,

wherein the second pixel electrode comprises a first edge separated from the first data line by a first distance, and a second edge separated from the second data line by a second distance same as the first distance.

2. The display device of claim 1 , further comprising:

a first thin film transistor connected to the first data line and the first pixel electrode; and

a second thin film transistor connected to the second data line and the second pixel electrode.

3. The display device of claim 2 , further comprising a storage line overlapped by the first and second pixel electrodes.

4. The display device of claim 3 , further comprising:

a first storage capacitor formed such that a first drain electrode extending from the first thin film transistor and connected to the first pixel electrode overlaps the storage line with an insulating layer disposed therebetween; and

a second storage capacitor formed such that a second drain electrode extending from the second thin film transistor and connected to the second pixel electrode overlaps the storage line with the insulating layer disposed therebetween.

5. The display device of claim 1 , further comprising a storage line overlapped by the first and second pixel electrodes.
