Display panel and display panel driving method
A display panel includes an optical element which has a pair of electrodes and exhibits an optical operation corresponding to an electric current flowing between the electrodes, and a switch circuit which supplies a memory current having a predetermined current value to a current line during a selection period, and stops the supply of the memory current to the current line during a non-selection period. A current memory circuit stores current data corresponding to the current value of the memory current flowing through the current line during the selection period and, in accordance with the current data stored during the selection period, supplies a display current having a current value substantially equal to the memory current to the optical element during the non-selection period.
