Abstract: A picture display device including a picture display section for projecting an input picture signal; a light source for visualizing a picture in the picture display section; a moving picture detecting section for outputting a scanning line movement determination signal for every scanning line based on a movement amount of a picture signal for every scanning line; a PWM pulse generating section for controlling flashing of the light source; and a PWM control section for outputting a moving image specifying signal that specifies a moving image area included in a frame based on the scanning line movement determination signal to control the PWM pulse generating section. The PWM control section controls the PWM pulse generating section in a blinking mode by turning off the light source in a period for scanning the moving image area including a scanning line having a largest movement amount.
