IMAGE DISPLAY ELEMENT HOLDING MECHANISM, PRISM UNIT, AND PROJECTOR

摘要

A holding mechanism for holding an image display element to a prism includes: a first fixing member fixed to the prism by an adhesive; and a second fixing member, which is fixed to the first fixing member using a screw, and which has the image display element directly or indirectly fixed to the second fixing member. A protruding section is provided at the periphery of a hole to be used for the purpose of fixing using the screw, and at the time of fixing the second fixing member to the first fixing member using the screw, the first fixing member and the second fixing member are directly or indirectly brought into contact with each other at the protruding section such that deformation due to screwing of the screw does not generate within a bonding region of the first fixing member.

1. An image display element holding mechanism for holding an image display element on a prism, comprising:
a first fixing member that is fixed to a prism with an adhesive agent; and a second fixing member that is fixed to the first fixing member with a screw, and to which an image display element is directly or indirectly fixed, wherein a protrusion is formed around a hole used for fixing with the screw, and the first fixing member and the second fixing member contact each other directly or indirectly at the protrusion so as to prevent distortion from being caused in an adhesion area of the first fixing member by tightening of the screw when fixing the first fixing member to the second fixing member with the screw.
