Abstract

According to one embodiment, a liquid crystal display device includes a first area, second area, liquid crystal layer, and a plurality of pixels. Each subpixel includes an opening area including a first opening area and a second opening area. The pixels include a first pixel positioned in the first area and a second pixel positioned over a boundary of the first area and the second area. The opening area of the second pixel is smaller than the opening area of the first pixel when opening areas of subpixels of same color are compared. An each imaginary line showing the boundary of the first opening area and the second opening area is a same straight line.

Claims (21)

1 .- 11 . (canceled)

12 . A display device comprising a display area, the display area comprising:

a plurality of scanning lines each extending in a row direction and arrayed in a column direction crossing the row direction;

a plurality of pixels arrayed in the row direction and the column direction; and

a light shielding layer over the plurality of pixels, wherein

the plurality of pixels comprise a first pixel including a first pixel electrode, a second pixel including a second pixel electrode, a third pixel including a third pixel electrode, a fourth pixel including a fourth pixel electrode, and a fifth pixel including a fifth pixel electrode,

the light shielding layer comprises a first opening overlapping with the first pixel electrode, a second opening overlapping with the second pixel electrode, a third opening overlapping with the third pixel electrode, a fourth opening overlapping with the fourth pixel electrode, and a fifth opening overlapping with the fifth pixel electrode,

an area of the second opening is smaller than an area of the first opening,

an area of the third opening is smaller than an area of the second opening,

an area of the fourth opening is smaller than an area of the third opening,

an area of the fifth opening is smaller than an area of the fourth opening, and

at most two selected from the second pixel, the third pixel, the fourth pixel, and the fifth pixel are positioned continuously in one row or in one column.

13 . The display device according to claim 12 , wherein

a width of the first opening in the row direction, a width of the second opening in the row direction, a width of the third opening in the row direction, a width of the fourth opening in the row direction, and a width of the fifth opening in the row direction are all equal to each other.

14 . The display device according to claim 12 , wherein

a difference between a width of the first opening in the column direction and a width of the second opening in the column direction, a difference between the width of the second opening in the column direction and a width of the third opening in the column direction, a difference between the width of the third opening in the column direction and a width of the fourth opening in the column direction, and a difference between the width of the fourth opening in the column direction and a width of the fifth opening in the column direction are all equal to each other.

15 . The display device according to claim 12 , wherein

an area of the first pixel electrode, an area of the second pixel electrode, an area of the third pixel electrode, an area of the fourth pixel electrode, and an area of the fifth pixel electrode are all equal to each other.

16 . The display device according to claim 12 , wherein

the first pixel, the third pixel, the fourth pixel, and the fifth pixel are positioned on an outermost part of the display area, and

the second pixel is not positioned on the outermost part of the display area.
