ABSTRACT:
A liquid crystal apparatus includes: a liquid crystal panel, an illumination means for illuminating the liquid crystal panel, a supporting means for supporting the liquid crystal panel and a housing for housing the above members. The liquid crystal panel and the supporting means are arranged so as to define an almost closed space functioning as an air damper to suppress deformation caused by an externally applied force owing to elasticity of air within the almost closed space. The supporting means includes a unit-supporting portion for supporting the illumination means, the unit-supporting portion being provided with a cutout at a part thereof for promoting discharge of heat evolved from the illumination means, and, the illumination means is supported by the unit-supporting portion so as to stop up the cutout of the unit-supporting portion, thus retaining the almost closed space. The liquid crystal apparatus is further provided with means for enhancing discharge of heat evolved by the illumination means out of the apparatus from a side opposite to the liquid crystal panel of the illumination means.
