Woled display device

Abstract

The invention provides a WOLED display device, comprising: a substrate, and a WOLED device disposed on the substrate; the substrate comprising a plurality of pixel areas, arranged in an array; the WOLED device comprising: an anode layer, a hole injection layer (HIL) disposed on the anode layer, and a plurality of light-emitting layers (EML), wherein a charge generation layer (CGL) being disposed between two adjacent EML layers, and the HIL layer contacting the anode layer; the HIL layer and/or at least a CGL layer being disposed correspondingly to the plurality of pixel areas, and broken off above banks between the two adjacent pixel areas; the present invention improves the physical structure of the WOLED display device so that the HIL layer and CGL layer have no lateral conduction characteristics for reduced pixel distance and higher driving voltage, leading to effective avoidance of light leakage.
