Title:

OPTICAL COMPENSATION ELEMENT ADJUSTING MECHANISM AND PROJECTOR

Document Type and Number:

WIPO Patent Application WO/2016/067580

Kind Code:

A1

Abstract:

One of the purposes of the present invention is to provide an optical compensation element adjusting mechanism and a projector which are able to adjust a tilt of an optical compensation element with high accuracy. The optical compensation element adjusting mechanism is provided with: an optical compensation element which optically compensates for a liquid crystal panel; and an adjustment frame which adjusts the angle of the optical compensation element with respect to the liquid crystal panel. The adjustment frame is provided with: a substantially rectangular holding section which holds the optical compensation element; a pair of fixing sections which extend from diagonal positions on the holding section toward a direction intersecting the holding section, and are fixed to a first holding member to which the adjustment frame is mounted; and an adjustment section which is disposed at a position apart from the pair of the fixing sections, and tilts the holding section around a virtual line connecting the pair of the fixing sections to tilt the optical compensation element.
