Abstract
A display device includes a light emitting element. A first transistor transmits a driving current to the light emitting element. A second transistor is connected to a first electrode of the first transistor to transmit a data signal. A third transistor has a first electrode connected to a second electrode of the first transistor. An auxiliary transistor is connected between a second electrode of the third transistor and a gate electrode of the first transistor to transmit the data signal to the gate electrode of the first transistor. Each of the first transistor, the second transistor and the auxiliary transistor is a first-type transistor, and the third transistor is a second-type transistor different from the first-type transistor.
