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.

Abstract: According to an aspect, an electrochromic device, includes: two electrodes facing each other in a first direction with an electrochromic material therebetween; an operational amplifier circuit an output of which is coupled to one of the two electrodes; a first wiring line coupled to a positive power supply coupling part of the operational amplifier circuit; a second wiring line provided as a transmission line for the output; a first contact coupling the first wiring line to a light-transmissive conductor layer configured to transmit a positive power supply potential of the operational amplifier circuit; and a second contact coupling the second wiring line to the one electrode. A distance between the first contact and the second contact in a second direction is larger than a distance between a part of the first wiring line and a part of the second wiring line that are aligned in parallel in the second direction.

Abstract: The display control circuit includes a drive signal generation circuit that generates a gate drive signal, a scanning line drive circuit that supplies the gate drive signal to the scanning line, and a first wire through which the gate drive signal from the drive signal generation circuit is supplied to the scanning line drive circuit. The drive signal generation circuit includes a first potential supply circuit that supplies, to the first wire, a first potential equal to or lower than an off-potential of the pixel transistor, a second potential supply circuit that supplies, to the first wire, a second potential lower than the first potential, a third potential supply circuit that supplies, to the first wire, a third potential higher than the first potential, and a fourth potential supply circuit that supplies, to the first wire, a fourth potential equal to or higher than an on-potential of the pixel transistor.
