Abstract

The aim of the invention is to reduce power consumption in an active matrix. type display device. A first drive transistor (2) and a second drive transistor (4) form a static memory. A data voltage from a data line (7) is input into the static memory via a gate transistor (5) and stored in the static memory. To the first and second driver transistors, first (1) and second (3) organic EL elements are connected, in which one of the first and second driver transistors is set capable of light emission and the other incapable of light emission. With this arrangement, light emission according to the data voltage is carried out.
