Liquid crystal display device
View Patent ↗A liquid crystal display device having a non-rectangular display panel includes an active area which is defined by a peripheral shield layer. A plurality of pixels are formed in the active area in a matrix, and each pixel includes a plurality of sub-pixels to display colors different from each other. A part of the sub-pixels of peripheral pixels located in a peripheral region of the active area is covered with a peripheral shield layer. Shield elements are arranged in the sub-pixels which are not covered with the peripheral shield layer so that an effective display area of each of the sub-pixels of the peripheral pixel is substantially equal.
1. A liquid crystal display device comprising:
a first substrate including wiring regions;
a second substrate facing the first substrate;
a liquid crystal layer interposed between the first and second substrates;
a peripheral shield layer defining an active area formed of the first and second substrates and the liquid crystal layer in a non-rectangular shape to display images;
a plurality of pixels formed in the active area, the pixels being arranged in a matrix and each pixel including a plurality of sub-pixels to display colors different from each other; and
peripheral pixels located in a peripheral region of the active area, and
wherein effective display areas of the sub-pixels in the peripheral pixels, in which at least one of the sub-pixels of at least one of the pixels is covered with the peripheral shield layer, are substantially equal.
2. The liquid crystal display device according to claim 1 , wherein the active area is formed in a substantially circular or elliptical shape.
3. The liquid crystal display device according to claim 1 , wherein at least one of the sub-pixels in the peripheral pixels includes a shield element to cover a part of the sub-pixel.
4. The liquid crystal display device according to claim 3 , wherein each of the pixels includes first and second sub-pixels, and
wherein the peripheral shield layer partially overlaps with the first sub-pixel, and the shield element is arranged in the second sub-pixel so that an effective display area of the second sub-pixel is substantially equal to that of the first sub-pixel in the peripheral pixels.
5. The liquid crystal display device according to claim 4 , wherein the shielded area covered with the peripheral shield layer in the first sub-pixel is substantially equal to that shielded by the shield element in the second sub-pixel.
6. The liquid crystal display device according to claim 3 , wherein the shield element is formed on the first substrate using the same material as a wiring region.
7. The liquid crystal display device according to claim 3 , wherein the shield element is formed on the second substrate using the same material as the peripheral shield layer.
8. A liquid crystal display device comprising:
a first substrate including wiring regions;
a second substrate facing the first substrate;
a liquid crystal layer interposed between the first and second substrates;
a peripheral shield layer defining an active area formed of the first and second substrates and the liquid crystal layer in a non-rectangular shape to display images;
a plurality of pixels formed in the active area, the pixels being arranged in a matrix and each pixel including first, second and third sub-pixels to display colors different from each other;
peripheral pixels arranged in a peripheral region of the active area so as to overlap with the peripheral shield layer; and
wherein the first and second sub-pixels in a peripheral pixel are shielded by the peripheral shield layer, and shield elements are arranged in the second and third sub-pixels of said peripheral pixel so that each effective display area of the first, second and third sub-pixels is substantially equal.
9. The liquid crystal display device according to claim 8 , wherein the active area is formed in a substantially circular or elliptical shape.
10. The liquid crystal display device according to claim 8 , wherein the first, second and third sub-pixels are red, green and blue color sub-pixels.
11. The liquid crystal display device according to claim 8 , wherein the shield element is formed on the first substrate using the same material as a wiring region.
12. The liquid crystal display device according to claim 8 , wherein the shield element is formed on the second substrate using the same material as the peripheral shield layer.
13. The liquid crystal display device according to claim 8 , wherein the shielded area covered with the peripheral shield layer in the second sub-pixel is smaller than that in the first sub-pixel, and the shielded area covered with the shield element in the third sub-pixel is larger than that in the second sub-pixel.
