Liquid crystal projector comprising a plurality of light shielding members fixed between the lens array and the polarized light generator

A projector that modulates polarized light by at least one liquid crystal light valve and projects an image, comprising;

• a light source that emits a light beam;
• a lens array that divides the light beam into a plurality of partial light beams;
• a polarized light generator to which the partial light beams are incident and that generates polarized light to be emitted to the at least one liquid crystal light valve;
• the polarized light generator includes:
• a plurality of polarization separating layers that separate each of the incident partial light beams into s-polarized light and p-polarized light;
• a plurality of reflecting layers that reflect the s-polarized light or the p-polarized light that was separated by the polarization separating layers, the polarization separating layers and the reflecting layers are arranged alternately;
• and
• a phase plate layer that unifies the separated s-polarized light and p-polarized light into one direction of polarization;
• and
• a plurality of stationary light shielding members unmovably fixed between a light incident side of the polarized light generator and the lens array, the plurality of light shielding members having a plurality of light shielding portions that are disposed corresponding to the reflecting layers, and the plurality of light shielding portions inhibiting the partial light beams from entering the reflecting layers.
