摘要： An image display device applies a higher voltage than the original voltage to the pixel, without causing deterioration of the display quality. The image display device includes a plurality of pixels each including a main capacitive element as a display element performing display operation in accordance with image data supplied to one end thereof. An auxiliary capacitive element has one end connected to the one end of the main capacitive element. A drive circuit drives each of the pixels, while supplying an additional potential to the other end of the auxiliary capacitive element in each of the pixels. The additional potential is individually determined so that a voltage between both ends of the main capacitive element rises higher than an original voltage.
