Abstract

A projector includes a light source; and a light modulator configured to modulate light output from the light source. The light modulator includes a liquid crystal layer, a light-incident-side substrate located on a light incident side of the liquid crystal layer, a light-exiting-side substrate located on a light exiting side of the liquid crystal layer, the light-exiting-side substrate and the light-incident-side substrate sandwiching the liquid crystal layer, a light-incident-side dustproof substrate that is a light transmissive substrate and located on a light incident side of the light-incident-side substrate, a light-exiting-side dustproof substrate that is a light transmissive substrate, and located on a light exiting side of the light-exiting-side substrate, the light-exiting-side dustproof substrate and the light-incident-side dustproof substrate sandwiching the liquid crystal layer, the light-incident-side substrate, and the light-exiting-side substrate, and a temperature control unit configured to control a temperature of the liquid crystal layer. A size of the light-incident-side dustproof substrate in a plan view is greater than a size of the light-incident-side substrate in the plan view when viewed from a light incident side of the light modulator. The temperature control unit is in contact with the light-incident-side dustproof substrate.
