Abstract
A display device includes a light emitting element disposed on a substrate, a first transistor which controls a driving current flowing in the light emitting element, a second transistor which supplies a data voltage to a gate electrode of the first transistor, a first-third transistor and a second-third transistor connected in series between the gate and drain electrodes of the first transistor, a first charge injection layer adjacent to a drain electrode of the first-third transistor electrically connected to the gate electrode of the first transistor on a semiconductor region of the first-third transistor, and a second charge injection layer adjacent to a source electrode of the second-third transistor integrally formed with the drain electrode of the first transistor on a semiconductor region of the second-third transistor. A charge injection area of the first charge injection layer is greater than a charge injection area of the second charge injection layer.
