Abstract

A multi-view image display device adapted to display images different from each other using one screen of a display panel is disclosed. The multi-view image display device includes a display panel inclusive of a first color filter array having a first red sub-pixel, a first green sub-pixel and a first blue sub-pixel that constitute a first image, and a second red sub-pixel, a second green sub-pixel and a second blue sub-pixel that constitute a second image; and a color filter barrier substrate inclusive of a second color filter array that is separated from the display panel with a fixed distance and has red, green and blue color filters. The red color filter of the second color filter array corresponds to the first blue sub-pixel and the second green sub-pixel of the first color filter array. The green color filter of the second color filter array corresponds to the first red sub-pixel and the second blue sub-pixel of the first color filter array. The blue color filter of the second color filter array corresponds to the first green sub-pixel and the second red-sub-pixel of the first color filter array.

Claims

1. A multi-view image display device comprising:

a display panel inclusive of a first color filter array having a first red sub-pixel, a first green sub-pixel and a first blue sub-pixel that constitute a first image, and a second red sub-pixel, a second green sub-pixel and a second blue sub-pixel that constitute a second image; and

a color filter barrier substrate inclusive of a second color filter array that is separated from the display panel with a fixed distance and has red, green and blue color filters,

wherein the red color filter of the second color filter array corresponds to the first blue sub-pixel and the second green sub-pixel of the first color filter array, the green color filter of the second color filter array corresponds to the first red sub-pixel and the second blue sub-pixel of the first color filter array, and the blue color filter of the second color filter array corresponds to the first green sub-pixel and the second red-sub-pixel of the first color filter array.

2. The multi-view image display device claimed as claim 1, wherein the width of one sub-pixel constituting the first color filter array is half the width of one sub-pixel that constitutes the second color filter array.

3. The multi-view image display device claimed as claim 1, wherein the display panel is a liquid crystal display panel, and the liquid crystal display panel has an upper substrate where the first color filter array is formed, a lower substrate where a thin film transistor array is formed, and a liquid crystal layer formed between the upper substrate and the lower substrate.

4. A multi-view image display device comprising:

a display panel inclusive of a first color filter array having a first red sub-pixel, a first green sub-pixel and a first blue sub-pixel that constitute a first image, a second red sub-pixel, a second green sub-pixel and a second blue sub-pixel that constitute a second image, a third red sub-pixel, a third green sub-pixel and a third blue sub-pixel that constitute a third image, and a fourth red sub-pixel, a fourth green sub-pixel and a fourth blue sub-pixel that constitute a fourth image; and

a color filter barrier substrate inclusive of a second color filter array that is separated from the display panel with a fixed distance and has red, green and blue color filters and a light shielding pattern that is formed between the color filters,

wherein the red color filter of the second color filter array has the central area thereof correspond to the first green sub-pixel and the fourth blue sub-pixel of the first color filter array and the edge area thereof correspond to half of each of the second and third red sub-pixels of the first color filter array, the green color filter of the second color filter array has the central area thereof correspond to the first blue sub-pixel and the fourth red sub-pixel of the first color filter array and the edge area thereof correspond to half of each of the second and third green sub-pixels of the first color filter array, and the blue color filter of the second color filter array has the central area thereof correspond to the first red sub-pixel and the fourth green sub-pixel of the first color filter array and the edge area thereof correspond to half of each of the second and third blue sub-pixels of the first color filter array.

5. The multi-view image display device claimed as claim 4, wherein the light shielding pattern between the red color filter and the blue color filter of the second color filter array corresponds to half of each of the second red sub-pixel and third blue sub-pixel of the first color filter array, the light shielding pattern between the red color filter and the green color filter of the second color filter array corresponds to half of each of the third red sub-pixel and second green sub-pixel of the first color filter array, and the light shielding pattern between the green color filter and the blue color filter of the second color filter array corresponds to half of each of the third green sub-pixel and second blue sub-pixel of the first color filter array.

6. The multi-view image display device claimed as claim 4, wherein the width of one sub-pixel constituting the first color filter array is ⅓

of the width of one sub-pixel constituting the second color filter array.

7. The multi-view image display device claimed as claim 4, wherein the width of the light shielding pattern is double the width of one sub-pixel constituting the first color filter array.

8. The multi-view image display device claimed as claim 4, wherein the display panel is a liquid crystal display panel, and the liquid crystal display panel has an upper substrate where the first color filter array is formed, a lower substrate where a thin film transistor array is formed, and a liquid crystal layer formed between the upper substrate and the lower substrate.
