Abstract
An optical compensation element adjusting mechanism capable of adjusting an inclination of an optical compensation element with high accuracy and a projector. The mechanism includes an optical compensation element which optically compensates a liquid crystal panel and an adjusting frame which adjusts an angle of the element to the liquid crystal panel. The adjusting frame includes an approximately rectangular holding portion which holds the optical compensation element, a pair of fixing portions which respectively extends from positions, which become a diagonal, of the holding portion in a direction intersecting with the holding portion and which is respectively fixed to a first holding member to which the adjusting frame is attached, and an adjusting portion which is disposed at a position away from the pair of fixing portions and which inclines the optical compensation element by inclining the holding portion around a virtual line connecting the pair of fixing portions.
