摘要：To reduce the arrangement interval between signal lines.SOLUTION: Anelectro-optical device comprises: a precharge circuit that supplies precharge signals to afirst signal line and a second signal line at different timings on the basis of a prechargecontrol signal; and an inspection circuit that outputs, to the precharge circuit, an

inspection control signal indicating whether the signal lines are objects to be inspected inan inspection operation. The precharge circuit includes: a first switch that switches anelectrical connection state between the first signal line and a precharge power supplyline between a conduction state and a non-conduction state on the basis of a firstconnection control signal; a second switch that switches an electrical connection statebetween the second signal line and the precharge power supply line between a

conduction state and a non-conduction state on the basis of a second connection controlsignal; a first signal selection circuit that outputs the first connection control signal to thefirst switch on the basis of the inspection control signal and the precharge control signal;and a second signal selection circuit that outputs the second connection control signal tothe second switch on the basis of the inspection control signal and the precharge controlsignal.SELECTED DRAWING: Figure 4
