Abstract
An electrochromic device includes: two electrodes with an electrochromic material therebetween; switching elements, a source or a drain of each of which is coupled to one of the two electrodes; scanning lines coupled to gates of the switching elements; transmission lines coupled to the other one of the source and the drain of each switching element; and first switches capable of individually switching coupling between a first wiring and each transmission line. A first period and a second period are alternately provided. In the first period, reset potentials of the transmission lines are given at either a first timing before a signal to be transmitted to the gates is given to the scanning lines or a second timing after the signal is given to the scanning lines. In the second period, the signal potential is given to the transmission lines at the other timing of the first and second timings.
