Abstract
In a liquid crystal device and a projection display device using the liquid crystal device as a light valve, for the purpose of preventing light incident from opposite the clear viewing direction from affecting the display, in a liquid crystal device ( ), an optical center position ( ) of a microlens ( ) formed on a counter substrate ( ) is offset toward the clear viewing direction as viewed from a center position ( ) of a first opening area ( ) formed for each pixel on the side of an active matrix substrate ( ). For this reason, light incident on the counter substrate ( ) from the direction inclined in the clear viewing direction is emitted from the active matrix substrate ( ); however, light incident from the direction inclined opposite to the clear viewing direction that causes the degradation of contrast is not emitted from the active matrix substrate ( ) and does not affect the display.
