Abstract
A display apparatus including a drive control section that performs control to repeatedly switch between a drive time period during which a backlight emits light and a rest time period during which the backlight does not emit light, in an alternating manner with a prescribed period. The drive control section controls a ratio between the drive time period and the rest time period, and controls the amount of drive current supplied to the backlight during the drive time period. The drive control section sets the rest time period to be a prescribed time period and controls the amount of the drive current for a range where an adjustment value is less than a prescribed value, and sets the drive current to a prescribed value and makes the rest time period shorter than the prescribed time period for a range where the adjustment value is greater than the prescribed value.
