Abstract
A display device and a manufacturing method of a display device are provided. A manufacturing method of a display device includes transferring light emitting elements onto a first electrode arranged on a pixel circuit layer, each of the light emitting elements including an undoped semiconductor layer spaced apart from the pixel circuit layer, patterning an inorganic layer covering the light emitting elements on the first electrode, forming a photosensitive material layer on the inorganic layer, and patterning the photosensitive material layer to expose a portion of the inorganic layer covering the undoped semiconductor layer.

A manufacturing method of a display device, the manufacturing method comprising:
- transferring light emitting elements onto a first electrode arranged on a pixel circuit layer, each of the light emitting elements comprising an undoped semiconductor layer spaced apart from the pixel circuit layer;
- patterning an inorganic layer covering the light emitting elements on the first electrode;
- forming a photosensitive material layer on the inorganic layer;
- and
- patterning the photosensitive material layer to expose a portion of the inorganic layer covering the undoped semiconductor layer.
A display device comprising:
- a pixel circuit layer comprising a base layer and a pixel circuit;
- a first electrode on the pixel circuit layer;
- light emitting elements on the first electrode and each comprising a first semiconductor layer including a first type semiconductor;
- an inorganic layer on the first electrode and covering the light emitting elements;
- and
- a second electrode on the light emitting elements,
- wherein the first semiconductor layer and the inorganic layer contact the second electrode.
