A display panel ( 110 ) comprises a plurality of optical elements (OEL) each having a pair of electrodes and performing an optical operation according to current passing between the pair of electrodes, a current line (DL), a switch circuit (Tr 2 ) that passes a write current (Ia) with a predetermined current value through the current line (DL) during a selection time (Tse) and stops passing current during a non-selection time (Tnse), and a current storage circuit (Tr 1 , Tr 2 , Cs, Cp) that stores current data according to the current value of the write current (Ia) passing through the current line (DL) during the selection time (Tse) and that supplies a drive current (Ib) having a current value, which is obtained by subtracting a predetermined offset current (Ioff) from the current value of the stored write current (Ia), to the optical elements (OEL) during the non-selection time (Tnse). The current storage circuit (Tr 1 , Tr 2 , Cs, Cp) includes a first capacitor device (Cs) to which an electrical charge corresponding to the write current (Ia) is written and a second capacitor device (Cp) to which an electrical charge corresponding to offset current (Ioff) is written, and the second capacitor device (Cp) has a capacitive value, which is equal to or larger than the first capacitor device (Cs).
