Abstract
An electroluminescent display device includes a display panel having scan lines, data lines, and pixel circuits. The pixel circuit includes an electroluminescent element having a first electrode layer, a first insulation film, and an emitting layer for displaying images. A driving circuit is coupled to the electroluminescent element. The first electrode layer is superimposed on a power source line, a scan line, or both, with a second insulation film therebetween.
Claims6
A method for manufacturing an electroluminescent display device including an electroluminescent element, a first insulation film, and a driving circuit coupled to the electroluminescent element, comprising:
- (a) forming a power source line for supplying power to the driving circuit;
- (b) forming a second insulation film to cover the power source line;
- (c) forming a first electrode layer of the electroluminescent element on the second insulation film, and superimposing at least part of the first electrode layer on the power source line;
- (d) forming a third insulation film with an aperture on a part of the first electrode layer that is horizontally separated from the power source line;
- (e) forming an emitting layer of the electroluminescent element on the aperture;
- and
- (f) forming a second electrode layer on the emitting layer.
