Abstract
A top emission type organic light emitting display includes an organic light emitting diode in which an anode, a light emitting layer and a transparent cathode are successively deposited. The cathode has a sandwiched structure in which a transparent oxide layer is inserted between the metal layers. Exemplary embodiments of the cathode of the present invention have better electric conductivity than a conventional cathode of an organic light emitting diode device, and thus has lower power consumption than a conventional top emission organic light emitting display with similar light transmission.
