Claim 10:
11. A display apparatus, comprising:
a display section;
a backlight including a plurality of light-emitting sections, the light-emitting sections being operable to emit light at mutually different timings and including a first light-emitting section and a second light-emitting section; and
a controller that controls a light emission operation of the backlight to cause the first light-emitting section and the second light-emitting section to emit light with mutually different light emission intensities in a first sub-frame period of a plurality of sub-frame periods corresponding to a frame period,
wherein,
the backlight unit comprises a diffuser plate that diffuses light emitted from the plurality of light-emitting sections to output diffused light, and
a gradient in a characteristic of the diffused light output from the diffuser plate as determined by fitting a portion of the characteristic to a sinusoidal waveform, is equal to or lower than a maximum gradient in a sine-wave grating having a spatial frequency based on a resolution of images displayed on a screen of the display apparatus and a distance from the screen.
