Patent ID: 8585215

Claim:
A projector comprising: a light source; a light amount control device configured to control an amount of passing light of a luminous flux emitted from the light source; an electro-optic unit configured to modulate the luminous flux passing through the light amount control device according to image data and form an image light; and a projection device configured to project the image light, the light amount control device includes: a light-shielding member configured to shield part of the luminous flux emitted from the light source; a holding member configured to hold the light-shielding member, the holding member being formed of a material having a coefficient of thermal conductivity lower than a coefficient of thermal conductivity of the light-shielding member; and a position changing unit configured to move or rotate in order to change the position of the light-shielding member, wherein the light-shielding member is attached to the position changing unit via the holding member, the light-shielding member comes into contact with the holding member via a projection provided on at least one of the light-shielding member and the holding member, the light amount control device has an area in which the light-shielding member and the holding member overlap, the projection, within the area, projects from at least one of the light-shielding member and the holding member in a direction of lamination, and abuts the other of the light-shielding member and the holding member, and the projection, which is formed on a surface of one of the light-shielding member and the holding member, contacts an opposing and adjacent surface of the other one of the light-shielding member and the holding member.
