Abstract
A wearable display device comprises a casing, a display panel, a lens and a prism. The display panel is disposed on the casing, and has two planes connected to each other. An angle between the planes is greater than 0 degrees and less than 180 degrees. The lens is disposed on the casing, and faces the planes. The prism is disposed between the display panel and the lens, and comprises two refractive portions. Each refractive portion has a light-incoming surface and a light-outgoing surface. The light-incoming surfaces respectively face the planes of the display panel. The light-outgoing surfaces face the lens. An angle between the light-outgoing surfaces is greater than 0 degrees and less than 180 degrees. One of the light-incoming surfaces is parallel to one of the planes of the display panel. The other light-incoming surface is parallel to the other plane of the display panel.
