In the present display device, a control section (15) divides each frame into a preceding subframe and a succeeding subframe and designates the preceding subframe for black display for low luminance and the succeeding subframe for white display for high luminance. That mitigates excess brightness phenomena. The control section (15) adjusts emission of a light source in the display section (14) by PWM light adjustment, setting the light adjustment frequency to n.5 times the frame frequency and not lower than 450 Hz. That prevents horizontal stripes from occurring. The light adjustment frequency is so raised that flickering is less recognizable.
