Abstract
A light-emitting chip structure, a display device, and a method for manufacturing a display device are provided. The light-emitting chip structure includes a protective layer, a buffer layer, an epitaxial layer, a patterned metal layer, a light-shielding layer, and an electrode layer. The epitaxial layer is divided into multiple epitaxial structures by multiple first gaps thereof. A side surface of a first semiconductor layer of the epitaxial layer is arranged with a protruding portion. One part of a patterned metal layer is disposed on a bottom of each of the first gaps to cover the protruding portion and a part of the buffer layer exposed through the first gaps, and the other part of the patterned metal layer is disposed on a side surface of the epitaxial structure at an edge of the light-emitting chip structure and a surface of the epitaxial structure away from the buffer layer.
