Abstract
A liquid crystal apparatus is constituted by a liquid crystal panel, illumination means for illuminating the liquid crystal panel, a heat dissipation member disposed with a spacing from the liquid crystal panel, and a heat conductive member. The apparatus further includes a heat deformation member which is disposed contactable to the heat conductive member and is deformable on receiving heat from the liquid crystal panel, so as to have the heat conductive member contact both the liquid crystal panel and the heat dissipation member thereby forming a heat conductive path between the liquid crystal panel and the heat dissipation member in a first position at a temperature of at least a prescribed temperature of the liquid crystal panel and to have the heat conductive member be separated from at least one of the liquid crystal panel and the heat dissipation member in a second position at a temperature below the prescribed temperature.
