Abstract
A near-eye display device, including a substrate, a light-emitting element, an active element, an optical layer, and a light guide structure, is provided. The light-emitting element is located on the substrate and includes a first type semiconductor pattern. The active element is located adjacent to the light-emitting element. A channel layer of the active element and the first type semiconductor pattern of the light-emitting element belong to the same layer. The optical layer covers the light-emitting element and the active element. The light guide structure is located on the optical layer and includes an in-coupling portion and an out-coupling portion, wherein an orthogonal projection of the in-coupling portion on the substrate is overlapped with an orthogonal projection of the light-emitting element on the substrate. A manufacturing method of the near-eye display device is also provided.
