Abstract: A display device that can switch between normal display and see-through display is provided. Visibility in see-through display is improved. A liquid crystal element overlaps with a light-emitting element. The light-emitting element, a transistor, and the like overlapping with the liquid crystal element transmit visible light. When the liquid crystal element blocks external light, an image is displayed with the light-emitting element. When the liquid crystal element transmits external light, an image displayed with the light-emitting element is superimposed on a transmission image through the liquid crystal element.

Abstract: Provided is a display device with extremely high resolution, a display device with higher display quality, a display device with improved viewing angle characteristics, or a flexible display device. Same-color subpixels are arranged in a zigzag pattern in a predetermined direction. In other words, when attention is paid to a subpixel, another two subpixels exhibiting the same color as the subpixel are preferably located upper right and lower right or upper left and lower left. Each pixel includes three subpixels arranged in an L shape. In addition, two pixels are combined so that pixel units including subpixel are arranged in matrix of 3×2.
