Abstract
The invention provides a projector which results in good contrast and high luminance by fine-adjusting a polarizer. The projector includes a polarizer angle adjustment mechanism in which a first frame arranged in the vicinity of an electrooptic device pivotally supports a second frame having a polarizer thereon. The second frame is pivoted by an adjustment member so that it can turn properly. By properly using the adjustment member, the polarization axes of the polarizer can be optimumly set, and a high-contrast and high-luminance image is thus presented.
