Abstract
A driving circuit of a display device like liquid crystal display, which is small in circuit size, ensures good quality images, and can freely change the display gradation, is configured to execute digital-analog conversion by reallocating charges between a primary-side capacitor and a secondary-side capacitor and includes a plurality of such capacitors in the primary side or the secondary side to enable both quick conversion and reliable potential output to signal lines. Also in an output circuit, output of signal potentials not affected by fluctuation of properties of TFT and inverters can be realized.
