Abstract
A light emitting display apparatus includes a substrate including a subpixel area having a non-light emission portion, a first light emission portion and a second light emission portion; a driving transistor disposed in the non-light emission portion; an overcoat layer disposed on the substrate to overlay the driving transistor; first and second anode electrodes disposed to be spaced apart from each other on the overcoat layer of each of the first light emission portion and the second light emission portion and commonly connected to the driving transistor; a self-light emitting device on the first anode electrode and the second anode electrode; and a second electrode on the self-light emitting device. The first light emission portion and the second light emission portion can have light extraction structures different from each other.
