In a half mirror of a head mounted display which is formed by stacking a dielectric film and a metal film to a plate-shaped resin member, reflectivity of a P-polarized light and reflectivity of an S-polarized light do not agree with each other in at least a partial band of a visible band which contains wavelengths of three primary colors which constitute the image light. On the other hand, the reflectivity of the P-polarized light and the reflectivity of the S-polarized light with respect to the three primary colors are set approximately equal. An average value of transmittance of the P-polarized light and transmittance of the S-polarized light with respect to the respective wavelengths in the visible band which contains the wavelengths of the three primary colors is suppressed to a value which falls within a regulated range in the whole visible band. |
