Abstract
An emissive display using an organic electroluminescent device is provided, in which the pixel circuit is simplified, the aperture ratio is increased, high resolution is achieved, and the power consumption is reduced. In the configuration, among the two sets of inverter circuits, one set of inverter circuit is formed by a circuit connecting an organic electoluminescent device and a transistor in series, and a transistor of a memory circuit is omitted. Also, in the mutual connection of the two sets of inverters, display data is inputted to a line connected to the gate of the transistor connected in series with the organic electoluminescent device, and owing to this connection, the write load is reduced, and the high resolution is achieved by enabling to write at high speed.
