Abstract
To provide a display device including a plurality of pixels; a light emitting element layer formed across the plurality of pixels; and a bank formed so as to separately define adjacent pixels among the plurality of pixels, wherein the light emitting element layer includes a p-doped hole transport layer containing p-dopant, and the p-doped hole transport layer is formed on each of the pixels such that the p-doped hole transport layers on the respective adjacent pixels are separated from each other on the bank.
Claims9
A display device, comprising:
- a plurality of pixels;
- a light emitting element layer formed across the plurality of pixels;
- and
- an insulating layer formed so as to separately define adjacent pixels among the plurality of pixels,
- wherein
- the light emitting element layer includes a p-doped hole transport layer containing p-dopant, and
- the p-doped hole transport layer is formed on each of the pixels such that the p-doped hole transport layers on respective adjacent pixels are separated from each other on the insulating layer.
