Abstract
The present application discloses a display device capable of performing favorable display in which flicker is not visually recognized while the power consumption of a scanning-side drive circuit, as well as a data-side drive circuit, can be reduced sufficiently when pause driving is performed. A pixel circuit including emission control transistors M, Min addition to a drive transistor Mincludes a switching element that is turned on based on a voltage of an emission control line Ei to initialize an organic EL element OL when the voltage of the emission control line Ei is at a level for turning off the emission control transistors M, M. For example, in some embodiments, the anode electrode of the organic EL element OL is connected to an initialization voltage line Vini via an N-channel transistor Mserving as the switching element, and the emission control line Ei is connected to the gate terminal of the transistor M. In the pixel circuit, the transistors M, M, M, and the like except for the transistor Mare all P-channel transistors.
