Abstract

A liquid crystal display is divided into a first region and a second region by a virtual central line that passes through a central point of the LCD and extends along a first direction, where the first region comprises a plurality of dots, each comprising a first pixel, a second pixel and a third pixel displaying different colors, wherein the plurality of dots are repeatedly arranged along a second direction intersecting the first direction and comprise a first dot and a second dot, wherein a first distance between the first pixel of the first dot and the central line is greater than a second distance between the first pixel of the second dot and the central line, and the area of the first pixel of the first dot is less than that of the first pixel of the second dot.

First claim

What is claimed is:

1. A liquid crystal display which is divided into a first region and a second region by a virtual central line which passes through a central point of the liquid crystal display and extends along a first direction, wherein the first region comprises a plurality of dots, each comprising a first pixel, a second pixel and a third pixel displaying different colors, wherein the plurality of dots is repeatedly arranged along a second direction intersecting the first direction and comprise a first dot and a second dot, wherein a first distance between the first pixel of the first dot and the central line is greater than a second distance between the first pixel of the second dot and the central line, and an area of the first pixel of the first dot is less than that of the first pixel of the second dot,
wherein an area of the second pixel of the first dot is greater than that of the first pixel of the first dot.

2. The liquid crystal display of claim 1 , wherein a maximum value of the first distance is two thirds of a length of the first region in the second direction.

3. The liquid crystal display of claim 1 , wherein a minimum value of the first distance is two thirds of a length of the first region in the second direction.

4. The liquid crystal display of claim 3 , wherein a maximum value of the second distance is two thirds of the length of the first region in the second direction.

5. A liquid crystal display which is divided into a first region and a second region by a virtual central line which passes through a central point of the liquid crystal display and extends along a first direction, wherein the first region comprises a plurality of dots, each comprising a first pixel, a second pixel and a third pixel displaying different colors, wherein the plurality of dots is repeatedly arranged along a second direction intersecting the first direction and comprise a first dot and a second dot, wherein a first distance between the first pixel of the first dot and the central line is greater than a second distance between the first pixel of the second dot and the central line, and an area of the first pixel of the first dot is less than that of the first pixel of the second dot,
wherein an area of the first dot is equal to that of the second dot.

6. The liquid crystal display of claim 5 , wherein a length of the first pixel of the first dot in the first direction is equal to a length of the first pixel of the second dot in the first direction.

7. The liquid crystal display of claim 6 , wherein a ratio of the area of the first pixel of the first dot and an area of the second pixel of the first dot ranges from 1:2 to less than 1:1.

8. The liquid crystal display of claim 7 , wherein the area of the second pixel of the first dot is equal to that of the third pixel of the first dot.

9. The liquid crystal display of claim 7 , wherein a ratio of the area of the first pixel of the first dot and the area of the first pixel of the second dot ranges from 3:5 to less than 1:1.

10. The liquid crystal display of claim 1 , wherein a color displayed by the first pixel has a longer wavelength than that of a color displayed by the second pixel, and the color displayed by the second pixel has a longer wavelength than that of a color displayed by the third pixel.

11. The liquid crystal display of claim 10 , wherein each of the plurality of dots repeatedly arranged along the second direction comprises three pixels as a basic unit, wherein the basic unit sequentially comprises a red pixel displaying red, a green pixel displaying green and a blue pixel displaying blue or a red pixel displaying red, a blue pixel displaying blue and a green pixel displaying green.

12. The liquid crystal display of claim 1 , wherein the liquid crystal display includes at least one of a curved part or a flexible part.

13. A liquid crystal display comprising:
a first substrate;
a second substrate which faces the first substrate; and
a plurality of data lines which are disposed on the first substrate and extend along a first direction,
wherein the liquid crystal display is divided into a first region and a second region by a virtual central line which passes through a central point of the liquid crystal display and extends along the first direction, and at least a portion of the data lines are provided in the first region, wherein the data lines provided in the first region comprise a first data line, a second data line and a third data line sequentially adjacent to each other as a basic unit, and the basic unit is repeated along a second direction intersecting the first direction, wherein the basic units comprise a first basic unit and a second basic unit, wherein a first distance between the first data line of the first basic unit and the central line is greater than a second distance between the first data line of the second basic unit and the central line, and a distance between the first data line of the first basic unit and the second data line of the first basic unit is less than a distance between the first data line of the second basic unit and the second data line of the second basic unit,
wherein a width of each of the basic units repeated along the second direction in the first and second regions are the same.

14. The liquid crystal display of claim 13 , wherein a maximum value of the first distance is two thirds of a length of the first region in the second direction.

15. The liquid crystal display of claim 13 , wherein a minimum value of the first distance is two thirds of a length of the first region in the second direction.

16. The liquid crystal display of claim 15 , wherein a maximum value of the second distance is two thirds of the length of the first region in the second direction.

17. The liquid crystal display of claim 13 , wherein a ratio of the distance between the first data line of the first basic unit and the second data line of the first basic unit and a distance between the second data line of the first basic unit and the third data line of the first basic unit ranges from 1:2 to less than 1:1.

18. The liquid crystal display of claim 17 , wherein a ratio of the distance between the first data line of the first basic unit and the second data line of the first basic unit and the distance between the first data line of the second basic unit and the second data line of the second basic unit ranges from 3:5 to less than 1:1.

19. The liquid crystal display of claim 13 , wherein the first data line of each basic unit is electrically connected to a red pixel displaying red.

20. The liquid crystal display of claim 13 , wherein the second data line of each basic unit is electrically connected to a red pixel displaying red.
