Abstract
In a pixel circuit (), TFTs () to () are connected and driven such that a threshold voltage Vth of a TFT (), which is a drive transistor, can be held in a threshold holding capacitor () having a capacitance value c, voltages, including a data potential Vdata representing an image to be displayed, can be held in a data holding capacitor () having a capacitance value c, and charges in the data holding capacitor () and the threshold holding capacitor () are redistributed at the time of light emission. As a result, a potential obtained by multiplying the data potential Vdata by c/(c+c) is provided to a gate potential of the TFT ().
