1. A liquid crystal panel comprising:
a first substrate that is a light-transmitting substrate;
a second substrate that is disposed facing the first substrate with a liquid crystal interposed between the first substrate and the second substrate and is a light-transmitting substrate;
a conductive layer provided on the first substrate on a side facing the liquid crystal and comprising a plurality of wiring lines or a plurality of electrodes;
an insulating layer stacked on the conductive layer on a side facing the liquid crystal;
a first electrode layer stacked on the insulating layer on a side facing the liquid crystal;
a second electrode layer provided on the second substrate on a side facing the liquid crystal; and
a switch capable of opening and closing a coupling path between the first electrode layer and a reset potential, wherein
a sheet resistance of the first electrode layer is higher than a sheet resistance of the conductive layer and a sheet resistance of the second electrode layer,
the conductive layer comprises a conductor interposed in a conduction path between the first electrode layer and the switch, and
the insulating layer has a contact hole that couples the first electrode layer and the conductor.
