Abstract
The invention provides an image display apparatus () comprising a lighting system (); a LCD element (); and an actuating means for varying the transmittance of the LCD element () according to image signals, wherein the LCD element () is designed such that when the angle of view with respect to a specified direction of a screen varies provided that the entire LCD element () is in a white display mode, transmittance varies such that it has peak values at viewing angles other than viewing angles in the vicinity of 0 degree, and wherein the lighting system () is designed such that the intensities of light beams emitted in the directions of the viewing angles in the vicinity of 0 degree are higher than the intensities of light beams emitted in the directions of the viewing angles at which the transmittance has a peak value.
