1. A display device comprising:

  • a light modulation device including a plurality of pixels disposed corresponding to respective intersections between a plurality of scan lines and a plurality of data lines;

    a light source adapted to irradiate the light modulation device with light in accordance with PWM control;

    a light modulation device control section adapted to control the light modulation deviceto select the plurality of scan lines by K lines (K is an integer not smaller than

         2), and then write a data signal into the pixels corresponding to the selected scan lines in an image update period, andto select at least a part of the plurality of scan lines line by line, and then write the data signal into the pixels corresponding to the selected scan line in an image display period subsequent to the image update period; and

    a light source control section adapted to perform the PWM control of the light source so as to set a duty ratio in a part of the image display period to be higher than the duty ratio in another part of the image display period in a case of irradiating the light modulation device with the light with a predetermined luminance.
