Abstract:
An image display apparatus capable of ensuring a wide view range is provided. The image display apparatus includes: an image display panel; a backlight located on a back surface side of the image display panel; prisms located between the image display panel and the backlight and configured to deflect incident light; a liquid crystal layer located between the image display panel and the backlight and configured to change a deflection direction of emitted light by changing a refractive index thereof according to a voltage applied thereto; a position detection section configured to detect a position of a user; and a control section configured to control the voltage applied to the liquid crystal layer, on the basis of information of the position of the user detected by the position detection section.
