| description | The invention provides a projector which has high light utilization efficiency and can switch irradiation areas. The projector includes: a light source; a polarization beam splitter that splits light from the light source into P-polarized light and S-polarized light; a first reflective display that modulates the separated P-polarized light; a second reflective display that modulates the separated S-polarized light; a projection lens on which reflected light from the reflective display is incident; and a deflection element disposed on the light emission side of the projection lens and capable of changing the traveling direction of the light in accordance with the incident polarized light.
提供一种光的利用效率高且能切换照射区域的投影仪。投影仪具备：光源；偏振分束器，其将来自上述光源的光分离成P偏振光和S偏振光；第一反射型显示器，其调制上述分离后的P偏振光；第二反射型显示器，其调制上述分离后的S偏振光；投射透镜，其供来自上述反射型显示器的反射光入射；以及偏转元件，其配置在上述投射透镜的光出射侧，能根据入射的偏振光使光的行进方向变化。 |
