Abstract
A light modulation device having a pixel arrangement region in which a plurality of pixels are arranged includes a first substrate, a second substrate disposed to be opposed to the first substrate via a liquid crystal layer, and a cooling member disposed on the opposite side of the first substrate with respect to the second substrate and thermally connected to the second substrate. The cooling member includes a hollow space in which working fluid is encapsulated and changes the working fluid in a liquid phase to the working fluid in a gas phase to cool the liquid crystal layer via the second substrate.
