Abstract
Each of pixels includes: a transparent upper electrode covering at least a part of the first region and at least a part of the second region; a reflective lower electrode disposed in the second region; a light-emitting film disposed between the transparent upper electrode and the reflective lower electrode, the light-emitting film being configured to emit light in response to supplied electric current; a thin film transistor disposed lower than the reflective lower electrode in the second region, the thin film transistor having a channel made of a transparent oxide; and a transparent low-resistive film that is made of the transparent oxide and interconnects the power-source potential supply line and the transparent upper electrode, the transparent low-resistive film being separate from an oxide film that is made of the transparent oxide and includes the channel and having a resistance lower than a resistance of the channel.
