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.

Abstract: According to one embodiment, there is a third column of third color (Blue) pixels and fourth (White) color pixels arranged alternately. The first set of a first (Red), a second (Green) and a third (Blue) color pixels along the first direction, and the second set of a first (Red), a second (Green) and a fourth (White) color pixels along the first direction are each defined as a composite color unit pixel. In the composite color unit pixels located at the first or second one along the first direction from composite color unit pixels to which color pixels of the third columns belongs, a connection pattern is designed that the pixels of the third columns are connected to the odd-numbered gate lines and the even-numbered gate lines, alternately, along the first direction.
