Abstract
A display device that includes a capacitor with low power consumption even when the number of subpixels included in a pixel is increased is provided. The area of an opening in a subpixel that controls transmission of white light is smaller than the area of an opening in each of subpixels that control transmission of red light, green light, and blue light. A transistor included in each subpixel includes an oxide semiconductor film. The capacitor includes a first electrode and a second electrode. The first electrode is a metal oxide film in contact with an inorganic insulating film over the transistor. The second electrode is a light-transmitting conductive film that is over the inorganic insulating film and is electrically connected to the transistor.
