Dimming panel and liquid crystal display device

A dimming panel comprising:

• a drive circuit;
• and
• dimming units arranged in one direction from a drive circuit,
• the dimming panel sequentially including a first substrate, a liquid crystal layer, and a second substrate,
• the first substrate sequentially including an insulating substrate, connection lines formed from a transparent conductive material and connected to the drive circuit, a first insulating layer, a lower-layer electrode and a third insulating layer, a first electrode, a second insulating layer, and a second electrode,
• the first electrode including first dimming electrodes disposed for the respective dimming units,
• each of the first dimming electrodes includes island electrodes spaced from each other in a plan view and electrically connected to each other,
• at least one of the island electrodes is electrically connected to the lower-layer electrode through a contact hole,
• each of the first dimming electrodes being electrically connected to one of the connection lines,
• an electrode width of at least one of the connection lines increases as a distance from the drive circuit increases, and
• the drive circuit is configured to control voltages applied to the respective first dimming electrodes and apply a constant voltage to the second electrode.
