Projector including parallelizing lens and polarizers

A projector comprising:

• a light source outputting a white light containing a first polarization component and a second polarization component;
• a parallelizing lens having a lens face parallelizing the white light outputted from the light source and a planar face opposite to the lens face;
• a first polarizer having a light incident surface and a light exiting surface and transmitting a light of the first polarization component of the white light and blocking a light of the second polarization component;
• a single light modulation device modulating the light based on an image signal and generating an image light;
• and
• a projection lens projecting the image light, wherein
• the light of the first polarization component transmitted through the first polarizer enters the single light modulation device,
• the planar face of the parallelizing lens and one of the light incident surface of the first polarizer and the light exiting surface of the first polarizer are in optical contact, and
• the planar face of the parallelizing lens and the one surface of the light incident surface and the light exiting surface of the first polarizer are bonded via an optical adhesive material.
