Abstract:
A pixel and a display device having the pixel, the pixel including: a light emitting element; a first transistor configured to control, in response to a voltage of a first node coupled to a gate electrode thereof, current to be supplied from a first power supply coupled with a first electrode thereof to a second power supply via the light emitting element; a storage capacitor coupled between the first node and the first power supply; a second transistor coupled between a data line and the first transistor; an initialization transistor coupled between the light emitting element and an initialization power supply to transmit a voltage of the initialization power supply the light emitting element; and a dummy transistor coupled between the light emitting element and the initialization power supply, and including a first electrode and a second electrode that are coupled with each other.
