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: A display device includes a planarization layer on a substrate, a pixel with an organic electroluminescence element on the planarization layer, a sealing layer covering the pixel, a terminal electrode arranged at an edge of the substrate, and a first wiring arranged over the sealing layer and electrically connected to the terminal electrode. The planarization layer has an outer edge that forms a step over the substrate between the pixel and the terminal electrode. The first wiring extends from above the sealing layer to intersect with the step. In a plan view, the step has a first protrusion of the planarization layer protruding in a direction of the terminal electrode, a second protrusion adjacent to the first protrusion and protruding in a direction of the terminal electrode, and an intermediate region between the first protrusion and the second protrusion.
