Abstract
A beam deflection layer includes: a first selective polarization conversion-splitter that splits first color light in an incident light beam into 1A color light and 1B color light having different polarization directions from each other; a first beam deflector that deflects the 1A first first color light in the light beam from the 1A first selective polarization conversion-splitter, a first selective polarization converter that converts polarization directions of the 1A first first color light and the 1B second first color light in the light beam from the 1A first beam deflector, and a 1B second beam deflector configured to deflect the 1B second first color light in the light beam from the first selective polarization converter. The first color light, the 1A color light, and the 1B color light each have a first wavelength band.
