Abstract
A liquid crystal display apparatus designed so that the viewing angle dependence is minimized without causing the displayed image to become unsharp. The liquid crystal display apparatus has a display surface (16) for displaying an image by a plurality of pixels, and a backlight (11) disposed at a side of the apparatus which is reverse to the display surface (16) to allow an approximately parallel light beam, which is approximately normal to the display surface (16), to enter each pixel of the display surface. A microlens array (20) is disposed at the viewing side of the display surface (16), and a diffusing element (21) is disposed in the vicinity of a surface conjugate with the display surface (16) which is formed by the microlens array (20).
