Abstract
A projection type liquid crystal display apparatus includes: a light source; a liquid crystal display device; and a projection lens projecting light modulated by the liquid crystal display device. The liquid crystal display device includes a liquid crystal layer, a pixel electrode section having two-dimensionally disposed pixel apertures through which light can pass, and first and second microlens arrays formed on a light entering side and a light exiting side of the device with respect to the liquid crystal layer, respectively, and being a two-dimensional array of first and second microlenses provided in association with the pixel apertures, respectively. The F-number of the first microlenses is set at a value equal to or greater than that of the projection lens. The first and second microlenses are disposed such that the groups of microlenses are located in the focus position of each other.
