Abstract

Embodiments may be directed to an LCD apparatus including: an array substrate including a pixel electrode in each pixel of a plurality of pixels of an image area; a color filter substrate including a common electrode facing the pixel electrode; and a liquid crystal layer between the array substrate and the color filter substrate, and the common electrode includes a first common electrode corresponding to a center portion of the image area and a second common electrode corresponding to a boundary portion of the image area.

Claims (23)

1. A liquid crystal display (LCD) apparatus, comprising:

an array substrate including a pixel electrode in each pixel of a plurality of pixels of an image area;

a color filter substrate including a common electrode facing the pixel electrode; and

a liquid crystal layer between the array substrate and the color filter substrate,

wherein the common electrode includes a first common electrode corresponding to a center portion of the image area and a second common electrode corresponding to a boundary portion of the image area.

2. The LCD apparatus as claimed in claim 1 , wherein the array substrate includes a first common voltage line for applying a first voltage to the first common electrode and a second common voltage line for applying a second voltage to the second common electrode.

3. The LCD apparatus as claimed in claim 2 , further comprising:

a first conductive protrusion connecting the first common voltage line to the first common electrode; and

a second conductive protrusion connecting the second common voltage line to the second common electrode.

4. The LCD apparatus as claimed in claim 3 , further comprising a driving integrated circuit (IC) connected to the first and second common voltage lines so that the first and second voltages are applied to the first and second common electrodes.

5. The LCD apparatus as claimed in claim 1 , wherein different voltages are applied to the first and second common electrodes.

6. A method of manufacturing a liquid crystal display (LCD) apparatus, the method comprising:

preparing an array substrate on which a pixel electrode is in each pixel of a plurality of pixels of an image area;

preparing a color filter substrate including a common electrode facing the pixel electrode, the common electrode including a first common electrode corresponding to a center portion of the image area and a second common electrode corresponding to a boundary portion of the image area; and

bonding the array substrate and the color filter substrate to each other such that a liquid crystal layer is disposed between the array substrate and the color filter substrate.

7. The method as claimed in claim 6 , further comprising:

forming a first common voltage line for applying a first voltage to the first common electrode on the array substrate; and

forming a second common voltage line for applying a second voltage to the second common electrode on the array substrate.

8. The method as claimed in claim 7 , further comprising:

forming a first conductive protrusion for connecting the first common voltage line to the first common electrode; and

forming a second conductive protrusion for connecting the second common voltage line to the second common electrode.

9. The method as claimed in claim 8 , further comprising installing a driving integrated circuit (IC) connected to the first and second common voltage lines so that the first and second voltages are applied to the first and second common electrodes on the array substrate.

10. The method as claimed in claim 6 , wherein different voltages are applied to the first common electrode and the second common electrode.
