Abstract
An image display device using the area control method for eliminating irregularities as seen from the side and also capable of lowering power consumption. The degree of flatness indicating the image flatness of an image in each image area is calculated, and in areas that are flat the light source luminance is set high in order to lessen irregularities as seen from the side; and in areas that are not flat the irregularities are difficult to perceive as seen from the side so an effect that cuts power consumption is obtained without having to correct the light source luminance.
