Abstract
A transmissive liquid crystal panel includes a pixel region where a plurality of pixels are arrayed, a liquid crystal layer configured to modulate light for the plurality of pixels, an incident section configured to make the light incident on liquid crystal layer, an emission section configured to emit, as image light, the light modulated by liquid crystal layer, and a vapor chamber including an opening section corresponding to pixel region, a heat receiving section provided around the opening section, and a heat radiating section configured to radiate heat received by heat receiving section, the vapor chamber vaporizing, with the heat received by heat receiving section, a coolant in a liquid phase encapsulated on an inside of the vapor chamber and radiating, with the heat radiating section, heat of the coolant in a gas phase to thereby condense the coolant in the gas phase into the coolant in the liquid phase.
