DISPLAY APPARATUS INCLUDING SUBSTRATE HOLE

Abstract:

Disclosed herein is an organic light emitting display apparatus. The organic light emitting display apparatus includes at least one thin film transistor and light emitting device on substrate, the light emitting device is apart from the substrate hole, and at least one isolation structure is disposed between the substrate hole and the light emitting device. Each thin film transistor includes source/drain electrodes, each light emitting device includes a first electrode, a light emitting layer, and a second electrode, the organic light emitting display apparatus includes a connection electrode connecting one of the source/drain electrodes of the thin film transistor to the first electrode of the light emitting device, and a planarization layer is disposed between the thin film transistor and the light emitting device. The isolation structure includes at least one undercut structure, and a height of each undercut structure is greater than a thickness of the light emitting layer.
