Abstract: A display device includes: a display panel with pixels; a dimming panel with dimming pixels; and a light source. When a pixel is controlled to be lit in white and a predetermined condition is satisfied, a blurring region is formed, and light from the light source is transmitted through the blurring region and the pixel. When a pixel is controlled to be lit up in white and the predetermined condition is not satisfied, the blurring region is not formed, the dimming pixel overlapping the pixel on a straight line along a direction in which the display panel faces the dimming panel is controlled to transmit light, and light from the light source is transmitted through the dimming pixel and the pixel. The predetermined condition is satisfied when the pixel controlled to be lit in white is at a predetermined distance or farther from an outer edge of a display area.

Abstract: In a liquid crystal display device that performs two-line inversion driving, a difference of a write period of a substantial video signal between a pair of pixel rows scanned with the same polarity is compensated. An input signal pre-processing circuit 42 receives display data DATA and an original data enable signal DTMG, generates and inputs a data enable signal DTMG_R and display data DATA_R to a driver control signal generation block 40. DTMG_R is reduced in the active period, and an interval of the active period between a (2n-1)-th row and a 2n-th row is set to be larger than an interval of the active period between the 2n-th row and a (2n+1)-th row. The input signal pre-processing circuit 42 reads out DATA of each row from a buffer as DATA_R in an active period of DTMG_R.
