Abstract

Disclosed herein are a liquid crystal display panel and a method for fabricating the same wherein color reproducibility and superior image quality are achieved. The liquid crystal display panel comprises a color filter array substrate including a black matrix and a plurality of color filters arranged on a substrate, wherein each of the color filter includes a first color filter, a second color filter and a third color filter, each of them yielding a different color; and at least one selected from a fourth color filter yielding a mixed color of the first and second color filters, a fifth color filter yielding a mixed color of the second and third color filters, and a sixth color filter yielding a mixed color of the first and third color filters.

Claims (15)

1. A liquid crystal display panel comprising:

a color filter array substrate including a black matrix to define a plurality of pixel regions and a plurality of color filters arranged in the pixel regions on a substrate,

wherein each of the color filters includes a first color filter, a second color filter and a third color filter, each of the color filters yielding a different color; and at least one selected from a fourth color filter yielding a mixed color of the first and second color filters, a fifth color filter yielding a mixed color of the second and third color filters, and a sixth color filter yielding a mixed color of the first and third color filters, and

wherein the fourth color filter includes a dummy first color filter and a dummy second color filter, the dummy first color filter extending from the first color filter and thinner than that of the first color filter, and the dummy second color filter extending from the second color filter, thinner than that of the second color filter, and overlapping the dummy first color filter,

the fifth color filter includes a dummy second color filter and a dummy third color filter, the dummy second color filter extending from the second color filter and thinner than that of the second color filter, and the dummy third color filter extending from the third color filter, thinner than that of the third color filter, and overlapping the dummy second color filter, and

the sixth color filter includes a dummy first color filter and a dummy third color filter, the dummy first color filter extending from the first color filter and thinner than that of the first color filter, and the dummy third color filter extending from the third color filter, thinner than that of the third color filter, and overlapping the dummy first color filter.

2. The liquid crystal display panel according to claim 1 , wherein the fourth color filter is arranged between the first and second color filters, the fifth color filter is arranged between the second and third color filters, and the sixth color filter is arranged between the first and third color filters.

3. The liquid crystal display panel according to claim 1 , wherein the dummy first color filter, the dummy second color filter and the dummy third color filter are about half the thickness of the first color filter, the second color filter and the third color filter, respectively.

4. The liquid crystal display panel according to claim 1 , wherein the first color filter yields red, the second color filter yields green, the third color filter yields blue, the fourth color filter yields yellow, the fifth color filter yields cyan and the sixth color filter yields pink.

5. The liquid crystal display panel according to claim 1 , wherein the color filter array substrate further includes;

a common electrode arranged on the color filter, and

at least a spacer arranged on the common electrode.

6. The liquid crystal display panel according to claim 1 , further comprising:

a thin film transistor array substrate joined to the color filter array substrate such that liquid crystal is interposed between the two substrates,

wherein the thin film transistor array substrate includes a thin film transistor, and a pixel electrode contacting the thin film transistor.
