1. A control method for a display device including a first liquid crystal panel, a second liquid crystal panel, and a third liquid crystal panel and being configured to display an image, based on emission light from the first liquid crystal panel, emission light from the second liquid crystal panel, and emission light from the third liquid crystal panel, the control method comprising:
supplying first color pixel data to the first liquid crystal panel, supplying second color pixel data being different from the first color pixel data to the second liquid crystal panel, and supplying third color pixel data being different from the first color pixel data and the second color pixel data to the third liquid crystal panel; and
reducing a gray scale level of pixel data supplied to panel pixels other than a reference panel pixel among a first panel pixel, a second panel pixel and a third panel pixel, the reference panel pixel being a panel pixel having the lowest transmittance among the first panel pixel of the first liquid crystal panel that corresponds to a first display pixel, the second panel pixel of the second liquid crystal panel that corresponds to the first display pixel, and the third panel pixel of the third liquid crystal panel that corresponds to the first display pixel, in the image.
