Abstract

The disclosure provides an adjusting device having an active region and a peripheral region adjacent to the active region. The adjusting device includes a first substrate, a first conducting layer, a first insulating layer, a second conducting layer, a second insulating layer, and a sealant layer. The first insulating layer is disposed on the first conducting layer and includes a first opening disposed in the peripheral region. The second conducting layer is disposed on the first conducting layer and electrically connected to the first conducting layer through the first opening. The second insulating layer includes multiple first protruding structures disposed in the peripheral region and on the first insulating layer. The sealant layer is disposed in the peripheral region and on the second insulating layer. The first opening is disposed between two of the first protruding structures.
