Patent ID: 8651672

Claim:
A projector comprising: a reflection type polarization plate which polarizes and separates entering light; a reflection type light modulation device which modulates entering light; a light transmissive component which transmits entering light; a support body which has a first side surface, a second side surface, and a third side surface to which being attached the reflection type polarization plate, the reflection type light modulation device, and the light transmissive component, and has a substantially sealed space between the reflection type polarization plate, the reflection type light modulation device, and the light transmissive component; an optical compensation element disposed within the support body; and a control member which supports the optical compensation element, wherein any one of the first side surface, the second side surface, and the third side surface has a concave portion concaved toward the inside of the support body to accommodate the control member, the control member has an operation section which controls the position of the optical compensation element around a predetermined axis, an operation notch through which the operation section projects to the outside of the support body is formed on the side wall of the concave portion, the control member has a pair of arms projecting in directions away from each other in the plan view; and a pair of fixing notches through each of which the corresponding one of the pair of the arms projects to the outside of the support body are formed on the side wall of the concave portion.
