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.

摘要： An optical system for image projection is disclosed which is easy to be manufactured and designed and capable of projecting a bright image with high contrast. The optical system includes an illumination optical system introducing a luminous flux emitted from a light source to an image-forming element through an optical surface having a light-splitting function, and a projection optical system projecting the luminous flux from the image-forming element through the optical surface onto a projection surface. The illumination optical system includes a conversion system which respectively converts the widths of the luminous flux in first and second cross-sections into widths different from those before entering thereinto. Conversion rates in the first and second cross-sections are different from each other.
