Abstract
A display apparatus including: a liquid crystal panel for displaying left and right images; a liquid crystal driver for writing an image signal into the liquid crystal panel; a backlight source for radiating light to the liquid crystal panel; and a controller for controlling the backlight source so that it emits the light during first emission periods which are set for a left viewing periods while a left image is viewed with a left eye and right viewing periods while a right image is viewed with a right eye, respectively, wherein the controller controls the backlight source so that it emits the light during a second emission period within a non-viewing period, during which no image is viewed, and sets a turn-off period during which the backlight source is turned off between the first and second emission periods.
