ABSTRACT:
An optical element11includes a bandpass filter made of a lamination of thin films respectively having different refraction factors so as to selectively allow light emitted from a backlight6to pass therethrough, and a polarizer3,a quarter-wavelength plate2located between the bandpass filter6and the polarizer3so as to prevent light incident from the side of the polarizer3from being reflected by the bandpass filter1and then emitted from the side of the polarizer3.
