Abstract: Disclosed is a display device that with low power consumption. The display device includes a first thin film transistor having a polycrystalline semiconductor layer in an active area and a second thin film transistor having an oxide semiconductor layer in the active area, wherein at least one opening disposed in a bending area has the same depth as one of a plurality of contact holes disposed in the active area, whereby the opening and the contact holes are formed through the same process, and the process is therefore simplified, and wherein a high-potential supply line and a low-potential supply line are disposed so as to be spaced apart from each other in the horizontal direction, whereas a reference line and the low-potential supply line are disposed so as to overlap each other, thereby preventing signal lines from being shorted.

Abstract: A multi-view display device displays a first image, a second image, and a third image generated using the arrangement structure of subpixels and color filters, the gaps between the subpixels, and the arrangement structure of black matrices. The first to third red subpixels of the first to third subpixel groups display a red portion of the first to third images, the first to third green subpixels of the first to third subpixel groups display a green portion of the first to third images, and the first to third blue subpixels of the first to third subpixel groups display a blue portion of the first to third images.
