Pixel circuit 210 includes a current programming circuit 240 and voltage programming transistors 251 and 252 . In order to set the tone of the light emission from the organic EL element 220 , the first and second voltage programming transistors 251 and 252 are set to the OFF and ON state, respectively, and voltage programming is carried out using a voltage signal Vout. Next, the states of the first and second voltage programming transistors 251 and 252 are switched, and current programming is carried out using a current signal Iout.
