ABSTRACT:
An organic light emitting display including: a driving thin film transistor (TFT) including a semiconductor layer on a substrate including a source electrode, a drain electrode, and an N-type oxide semiconductor; at least one insulating layer formed on the driving TFT; a pixel defining layer for defining a pixel region on the insulating layer; a cathode electrode coupled to a drain electrode of the driving TFT and patterned to correspond to the pixel region; an electron injection layer arranged over the entire surfaces of the pixel defining layer and the cathode electrode and formed of a material whose band gaps are 3.0 eV to 5.0 eV selected from the group consisting of an oxide, a nitride, a fluoride, and diamond on; an organic light emitting layer formed on the electron injection layer to correspond to the cathode region; and an anode electrode formed on the organic light emitting layer.
