Abstract: A display device includes a light emitting element including an anode, a cathode, and a light emitting layer between the anode and the cathode, a first transistor connected between the anode and a first power line, the first transistor may be switched by a voltage of a node, a second transistor connected between the first transistor and a data line, the second transistor may be switched by a write scan signal, a third transistor connected between the node and the anode, the third transistor may be switched by a compensation scan signal, a fourth transistor connected between the node and an initialization line, the fourth transistor may be switched by an initialization scan signal, an insulating layer on the first to the fourth transistors, and a light blocking pattern protruding from the insulating layer, the light blocking pattern being adjacent to the third transistor and the fourth transistor.
