Abstract
A liquid crystal display device includes an array substrate, a counter substrate and a liquid crystal layer held between the array substrate and the counter substrate. A display portion having a plurality of pixels arranged in a matrix is formed of the substrates and the liquid crystal layer. Each of the pixels includes a pixel electrode and a counter electrode arranged opposing to the pixel electrode. A driving portion is formed on the array substrate to supply a pixel voltage to the pixel electrode. A correcting circuit is formed on the array substrate to correct the voltage supplied to the pixel electrode by adding a predetermined DC voltage to the voltage supplied to the pixel electrode corresponding to gradations to be displayed in the pixel.
