DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240179955 titled 'DISPLAY DEVICE
Simplified Explanation
The display device described in the patent application includes a pixel electrode, a pixel defining layer with an opening exposing part of the pixel electrode, an auxiliary electrode on the pixel defining layer and pixel electrode, an intermediate layer, and a common electrode on the intermediate layer. The pixel defining layer has a recessed portion, the auxiliary electrode has a first undercut forming portion on the recessed portion contacting the pixel electrode, and the intermediate layer includes a hole injection layer, a light-emitting layer, and an electron injection layer stacked sequentially. The hole injection layer has a first portion on the first undercut forming portion and a second portion on the recessed portion.
