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. 光束偏转层包括：第一选择性偏振转换分束器，将入射光束中的第一颜色光分裂成具有彼此不同的偏振方向的第一第一颜色光和第二第一颜色光；第一光束偏转器，使来自第一选择性偏振转换分束器的光束中的第一第一颜色光偏转；第一选择性偏振转换器，转换来自所述第一光束偏转器的光束中的第一第一颜色光和第二第一颜色光的偏振方向；和第二光束偏转器，配置为使来自第一选择性偏振转换器的光束中的第二
