DISPLAY DEVICE AND METHOD FOR FABRICATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240114726 titled 'DISPLAY DEVICE AND METHOD FOR FABRICATING THE SAME
Simplified Explanation
The display device described in the patent application includes first and second pixel electrodes, an inorganic insulating layer, a bank structure, light emitting layers, and common electrodes. The bank structure consists of multiple layers, including a first bank layer, a second bank layer with a different metal material, and a third bank layer with an oxide semiconductor layer. Each of the second and third bank layers has tips on sidewalls defining the openings over the pixel electrodes.
- First and second pixel electrodes on a substrate
- Inorganic insulating layer with portions on the pixel electrodes
- Bank structure with overlapping openings over the pixel electrodes
- Light emitting layers on the pixel electrodes
- Common electrodes on the light emitting layers
