Abstract
A reflective liquid crystal display device capable of favorable display is provided. A reflective liquid crystal display device having a high aperture ratio is provided. A reflective film is provided on the counter substrate side. An oxide conductor film is used as an electrode of a capacitor or a liquid crystal element. Specifically, a display device includes a transistor, an insulating film, a capacitor, a liquid crystal element, and a reflective film. The transistor is electrically connected to the capacitor and the liquid crystal element. The transistor includes an oxide semiconductor film. The capacitor transmits visible light. The capacitor or the liquid crystal element includes an oxide conductor film as at least one of a pair of electrodes. The oxide semiconductor film is opposite to the oxide conductor film with the insulating film therebetween. The reflective film is opposite to the transistor with the liquid crystal element therebetween.
