摘要:
An electroluminescence display having a repair structure comprises: a pixel comprising a thin film transistor and a light emitting diode, the thin film transistor including a semiconductor layer, a gate electrode, a source electrode, and a drain electrode, and the light emitting diode including an anode electrode that is connected to the thin film transistor; a repair element having a welding part that is configured to be connected to the thin film transistor; a planarization layer on the repair element and including a depression that overlaps the welding part of the repair element; and an organic material in the depression, wherein the anode electrode includes a first anode electrode layer and a second anode electrode layer, the first anode electrode layer including a portion that is disposed in the depression, and the second anode electrode layer being on the first anode electrode layer and the organic material.
