A pixel circuit for a display device includes a light emitting element, a driving transistor for driving the light emitting element, a scan transistor controlled by a scan signal supplied from a gate line and controlling a connection between a first node of the driving transistor and a data line, a storage capacitor connected between the first node of the driving transistor and a second node of the driving transistor, and a driving control diode connected between the second node of the driving transistor and a reference voltage line.

Pixel circuit and display device

A display device may comprise a substrate, a plurality of driving transistors on the substrate, a plurality of anode electrodes connected with the plurality of driving transistors, a light emitting layer on the plurality of anode electrodes, and a plurality of split cathode electrodes on the light emitting layer. Each of the plurality of split cathode electrodes may alternate between a first state applied with a cathode voltage and a second state of floating not applied with the cathode voltage.
