Abstract
An image display device is capable of displaying an image, in which occurrence of color unevenness is suppressed. A method of driving the image display device is also disclosed. In an area above the dotted line, red light is transmitted in a first sub-frame period. In second and third sub-frame periods, light blocking data are respectively supplied as green data and blue data. Therefore, green light and blue light cannot be transmitted through the area. Hence, a red image with no color unevenness is displayed in the area. In contrast, in an area under the dotted line, the red light is transmitted in the first sub-frame period, and the green light is transmitted in the second sub-frame period. As a result, in a viewed image of the area, there is color unevenness where green is mixed to red.
