The present invention provides a digital-analog converting circuit capable of shortening time necessary to digital-analog conversion. The present invention has 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. The electric charges in accordance with the digital pixel signal are accumulated to 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 OFF period of the switching circuit, the capacitor can hold the electric charge in accordance with the pixel data.
