Claim 1:
2. A dimming panel sequentially comprising:
a first substrate;
a liquid crystal layer;
a second substrate;
a drive circuit; and
dimming units arranged in an in-plane direction,
the first substrate sequentially including an insulating substrate, a first electrode, a first insulator layer, and a second electrode,
the first electrode including first dimming electrodes arranged in the respective dimming units,
the second electrode including, in a plan view, linear electrodes parallel to each other with slit regions in between, and bridge electrodes each of which is disposed in one of the slit regions and is connecting two adjacent linear electrodes,
the slit regions including a first slit region, a second slit region adjacent to the first slit region, and a third slit region adjacent to the second slit region,
the bridge electrodes including a first bridge electrode in the first slit region, a second bridge electrode in the second slit region, and a third bridge electrode in the third slit region,
the first bridge electrode, the second bridge electrode, and the third bridge electrode being discrete from one another, and
the drive circuit being configured to control voltages to be applied to the respective first dimming electrodes and applying a constant voltage to the second electrode.
