Organic light emitting diode display device

A display device having a plurality of subpixels, the display device comprising:

• a first substrate;
• a bank layer on the first substrate at boundaries between the plurality of subpixels;
• a thin film transistor in one of the subpixels;
• a light emitting diode in the one of the subpixels and electrically connected to the thin film transistor, the light emitting diode including an anode, a hole transporting layer, a first emitting layer, an electron transporting layer, and a cathode;
• and
• a spacer on the bank layer at a periphery of the one of the subpixels, the spacer having a reverse taper shape,
• wherein the cathode includes at least two discontinuous segments disconnected from each other at one or more side surfaces of the spacer, and the cathode does not cover at least a portion of the one or more side surfaces of the spacer, and
• wherein the spacer is disposed between the one of the subpixels and one other of the subpixels, and the spacer is not disposed between two of the subpixels other than the one of the subpixels.

A display device having a plurality of subpixels, the display device comprising:

• a first substrate;
• a bank layer on the first substrate at boundaries between the plurality of subpixels, the bank layer including a groove at a top surface of the bank layer in a periphery of one of the subpixels, the groove having a reverse taper shape;
• a thin film transistor in the one of the subpixels;
• and
• a first light emitting diode in the one of the subpixels and electrically connected to the thin film transistor, the first light emitting diode including an anode, a hole transporting layer, an emitting layer, an electron transporting layer, and a cathode,
• wherein at least one of the hole transporting layer and the electron transporting layer extends on the bank layer, including one or more side surfaces and a bottom surface of the groove, to be connected to an adjacent one of the subpixels,
• wherein the cathode is discontinuous at the one or more side surfaces of the groove, and
• wherein the groove is disposed between the one of the subpixels and one other of the subpixels, and the groove is not disposed between two of the subpixels other than the one of the subpixels.
