Display element, polarizing plate, and display apparatus and projecting apparatus using the display element and polarizing plate |
摘要 |
This invention provides a liquid crystal display apparatus which can reduce thermal load on a polarizing plate or display element, decrease the number of components necessary for reducing the thermal load on the polarizing plate, and reduce cost by decreasing the power consumption of a cooling fan. The display apparatus has a unit for changing the color purity of at least one of a puerility of colors. A polarizing plate in the optical path of light whose color purity is changed by the color purity changing unit is formed from a heat-transfer transparent substrate having a thermal conductivity of 1.2 W/(m.K) or more.
