Abstract:
To provide a head-mounted display that can obtain a higher sense of immersion without sensing coloring by diffusing and transmitting light from an organic electroluminescence display panel by an anisotropic optical film to reduce the visibility of a black matrix (BM). The head-mounted display is provided with an anisotropic optical film on the viewing side with respect to a color filter or an RGB light emitting layer in an organic electroluminescence display panel, said anisotropic optical film having a linear transmittance that varies depending on an incident light angle. The head-mounted display is characterized in that: the anisotropic optical film includes at least a single or a plurality of anisotropic light diffusion layers; and the anisotropic light diffusion layers have a matrix region and a plurality of pillar regions having refractive indexes different from that of the matrix region.
