A digital-analog converting circuit capable of shortening time necessary to digital-analog conversion. The converting circuit includes first switching circuits for turning on/off in accordance with a digital pixel signal, second switching circuits connected to the first switching circuit, first through third capacitors, and third through seventh switching circuits. Electric charges corresponding to the digital pixel signal are accumulated in the second capacitors. When the accumulation of the electric charges is completed, the switching circuit is turned on in order to transfer the accumulated electric charges into the third capacitor. Because of this, during an OFF period of the switching circuit, the third capacitor can hold the electric charge in accordance with the pixel data.
