Abstract
A display device and a splicing display device are provided. The display device includes a substrate layer, a capping layer, and a light-emitting element. The capping layer is disposed on the substrate layer and has a light-exiting region. The light-emitting element is disposed on the substrate layer and emits light toward the light-exiting region of the capping layer. A distance from the light-exiting region to the side surface of the capping layer is defined as D. A thickness of the capping layer is defined as T. A refractive index of the capping layer is defined as n1. D, T, and n1 meet the following equation: Tan(D/T)>Sin(1/n1). The splicing display device includes a plurality of display devices, and the display devices are spliced together. In the display device and the splicing display device, optical defects such as a shining edge, a ghost image, or a shadow effect are reduced.
