Abstract

There are provided a display device having dual color filter patterns and a manufacturing method thereof. The liquid crystal display device includes an array substrate including first color filter patterns, a counter substrate including second color filter patterns, and a liquid crystal layer interposed between the array substrate and the counter substrate, wherein the first color filter patterns and the second color filter patterns include photoresists having different color coordinates.

Claims (12)

1. A liquid crystal display device comprising:

an array substrate including first color filter patterns;

a counter substrate including second color filter patterns; and

a liquid crystal layer interposed between the array substrate and the counter substrate,

wherein the first color filter patterns are RGB patterns and include photoresists including red, green, and blue pigments, respectively, and the second color filter patterns are RGB patterns and include photoresists including red, green, and blue pigments, respectively,

wherein the RGB patterns of the first color filter patterns correspond to the RGB patterns of the second color filter patterns, respectively, and

wherein the RGB patterns of the first color filter patterns and the RGB patterns of the second color filter patterns include the photoresists having different color coordinates, respectively.

2. The liquid crystal display device as claimed in claim 1 , wherein the photoresists of the RGB patterns of the first color filter patterns include pigments of C.I. pigment red 177, C.I. pigment green 58, and C.I. pigment blue 15:6, respectively, and the photoresists of the RGB patterns of the second color filter patterns include pigments of C.I. pigment red 254, C.I. pigment yellow 138, and C.I. pigment violet 23, respectively.

3. The liquid crystal display device as claimed in claim 1 , wherein the photoresists of the RGB patterns of the second color filter patterns include pigments of C.I. pigment red 177, C.I. pigment green 58, and C.I. pigment blue 15:6, respectively, and the photoresists of the RGB patterns of the first color filter patterns include pigments of C.I. pigment red 254, C.I. pigment yellow 138, and C.I. pigment violet 23, respectively.

4. The liquid crystal display device as claimed in claim 1 , wherein

the array substrate includes a lower substrate, gate and data lines intersecting each other to define pixel regions, a thin film transistor (TFT) connected to the gate and data lines, the first color filter patterns, and a pixel electrode connected to the TFT, and

the counter substrate includes an upper substrate, a black matrix corresponding to the gate and data lines and the TFT, the second color filter patterns, and a common electrode covering the black matrix and the second color filter patterns.
