<p>Disclosed is an image display device using the field sequential method and capable of more efficiently suppressing occurrence of color breakup. One frame period is configured from single-color lighting subframes and an extended subframe in which a multicolor light source can assume arbitrary states. A color breakup intensity calculation unit (462) calculates for each mixed color component a color breakup intensity representing susceptibility to color breakup. A light source control signal generation/output unit (464) controls the light sources such that the greater the color breakup intensity of the mixed color component with the greatest color breakup intensity, the greater the amount of said mixed-color component is included in the light emitted from a light source unit in the extended subframe. Here, when an arbitrary mixed color component is set as a target component, if there is a first pixel region displayed which contains the target component and there is a second pixel region displayed in which the largest single-color component is smaller than the target component in the first pixel region, then the shorter the distance between the first pixel region and the second pixel region, the higher the color break intensity of the target component.</p> |
