Abstract
A display device comprises a display panel composed of a pixel portion in which a plurality of TFTs are arranged in matrix, a source driver, and a gate driver, an image signal processing circuit for processing an image signal input from an external, and a control circuit for controlling the display panel and the image signal processing circuit. The image signal processing circuit corrects the image signal on the basis of a correction table. By feeding the display panel with the corrected image signal, the display device can provide a good quality image.
