Abstract
An optical filter including: a polarizing film; and a plurality of phase delay films laminated on one side of the polarizing film, the optical axes of the phase delay films crossing each other, the plurality of phase delay films phase-delaying light having wavelengths in the visible range incident through the polarizing film and phase-delaying light reflected from a surface, thereby allowing the incident light to be interfered with and offset by the reflected light.
