Abstract

A display device includes: a plurality of pixels on a substrate, each of the plurality of pixels including a light emitting element and a pixel circuit configured to drive the light emitting element, wherein the pixel circuit of each of the plurality of pixels comprises: a first-first transistor configured to control a driving current flowing through the light emitting element based on a voltage of a first node; a first-second transistor connected in series with the first-first transistor and configured to control the driving current based on a voltage of a second node; a second transistor configured to selectively supply a data voltage to a third node which is a first electrode of the first-first transistor; a third-first transistor connected between the first node and a fourth node which is a second electrode of the first-second transistor; and a third-second transistor connected between the second node and the fourth node.
