Abstract
A compensation element adjustment mechanism used with a light modulation device and a polarization plate includes: an optical compensation element disposed between the light modulation device and a polarization plate; a frame for supporting the optical compensation element, and having a pair of shaft members disposed at positions opposed to each other on a periphery of the optical compensation element; a support holder to be fixed with respect to the light modulation device, and for rotatably supporting the pair of shaft members; and a fixing section for restricting a displacement of the frame to the support holder by an elastic contact.

A compensation element adjustment mechanism comprising:
- an optical compensation element disposed between a light modulation device and a polarization plate;
- a frame for supporting the optical compensation element, and having a pair of shaft members disposed at positions opposed to each other on a periphery of the optical compensation element;
- a support holder to be fixed with respect to the light modulation device, and for rotatably supporting the pair of shaft members;
- and
- a fixing section for restricting a displacement of the frame to the support holder by an elastic contact,
- wherein:
- the fixing section includes a first member attached to the support holder and a second member extending from the frame, and restricts the displacement of the frame to the support holder by an elastic contact between the first and second members, and
- the fixing section includes any one of a resin spring and a metal plate spring provided to any one of the first member and the second member.
