摘要: 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.

摘要: A D/A conversion circuit with a small area is provided. In the D/A conversion circuit, according to a digital signal transmitted from address lines of an address decoder, one of four gradation voltage lines is selected. A circuit including two N-channel TFTs is connected in series to a circuit including two P-channel TFT, and a circuit including the circuits connected in series to each other is connected in parallel to each of the gradation voltage lines. Further, an arrangement of the circuit including the two N-channel TFTs and the circuit including the two P-channel TFTs is reversed for every gradation voltage line. By this, the crossings of wiring lines in the D/A conversion circuit becomes small and the area can be made small.
