Publication number: 20180149932Abstract: 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.Type: ApplicationFiled: November 15, 2017Publication date: May 31, 2018Applicant: Japan Display Inc.Inventors: Masato NAKAMURA, Daichi Hosokawa, Yuki Kuramoto, Hideyuki Takahashi
