Light adjustment device and panel unit

A light adjustment device comprising:

• a panel unit in which a plurality of light adjustment panels are stacked in a first direction, each light adjustment panel being shaped as a polygon and including a first substrate that is translucent and a second substrate that is translucent and overlapping the first substrate;
• and
• a light source disposed on one side relative to the panel unit in the first direction, wherein
• the first substrate or the second substrate in each of the light adjustment panels includes
• a light adjustment region that is irradiated with light from the light source, and
• a first wire and a second wire disposed around the light adjustment region,
• the first wire serves as a first shaded region covering an area between at least one side among a plurality of sides of the polygon and the light adjustment region,
• the second wire serves as a second shaded region covering an area between a non-shaded region at an edge part along another side among the sides and the light adjustment region, and
• when the panel unit is viewed in the first direction, the first wires of the respective light adjustment panels are disposed along all sides of the panel unit and shade non-shaded regions of the respective light adjustment panels.
