Abstract: A light adjustment device includes a panel unit having a rectangular pillar shape and including a plurality of light adjustment panels stacked in a first direction, each light adjustment panel having a polygonal shape and including a lower substrate and an upper substrate overlapping the lower substrate. The light adjustment panels each have a first side, a second side adjacent to the first side, and a first corner at which the first side intersects the second side, and when two light adjustment panels adjacent to each other in a first direction among the light adjustment panels are viewed in the first direction, the first corner of one of the light adjustment panels is positioned inside of an edge of the other light adjustment panel, and the first corner of the other light adjustment panel is positioned inside of an edge of the one light adjustment panel.

Abstract: A circuit substrate includes, on an insulating substrate, a plurality of devices, a plurality of conductive layers connected in one-to-one correspondence with the devices, and an insulating layer provided between the devices and the conductive layers. The insulating layer includes a first insulating layer covering the devices, a second insulating layer formed on the first insulating layer, and a plurality of contact holes each passing through the first and second insulating layers in a thickness direction thereof. Side surfaces of the first and second insulating layers contact each other in at least part of the inside of each contact hole. Each conductive layer extends along an upper surface of the second insulating layer, at least a part of a side surface of the contact hole in which the side surfaces of the first and second insulating layers contact each other, and a bottom surface of the contact hole.
