Abstract
The disclosure provides a display device and an optical compensation module. The display device includes a light emitting display module and the optical compensation module. The optical compensation module is disposed on the light emitting display module along the transmission direction of an image beam emitted by the light emitting display module, and includes: a first polarizing layer and an optical compensation layer. The optical compensation layer is disposed between the light emitting display module and the first polarizing layer along the transmission direction of the image beam and has a first compensation area and a second compensation area which forms a pattern, wherein the phase compensation value of the first compensation area and the phase compensation value of the second compensation area are different. The display device and the optical compensation module have the effect of displaying the pattern on the display panel at a specific angle.
