ABSTRACT:
The pixels of a top emission display include a light emission device having a transparent pixel electrode and a metal pixel electrode on both surfaces of a light emitting layer and a driving circuit controlling the driving current of the light emission device. The driving circuit is formed on a substrate, and the light emission device is formed as a layer above the driving circuit with an intermediate layer of insulation material interposed therebetween. The transparent pixel electrode is situated opposite to the substrate. The metal pixel electrode device is connected with the driving circuit through a conduction portion which extends through the intermediate layer. Thus, light emitted from the light emission device can be prevented from reaching transistors by locating the transistors below the metal pixel electrode, and leakage current produced by the light of a transistor in the off state can be suppressed to prevent degradation of the image quality.
