Abstract: A pixel includes a light emitting element including an anode and a cathode, a first transistor connected between the anode and a first power line and switched by a voltage of a node, a second transistor connected between the first transistor connected to the first power line and a data line and switched by a write scan signal, a third transistor connected between the node and the anode and switched by a compensation scan signal, and an insulating layer covering the second and third transistors. A first groove is defined in a portion of the insulating layer adjacent to the third transistor.
