Adjusting device

An adjusting device, comprising an active region and a peripheral region, wherein the peripheral region is adjacent to the active region, and the adjusting device comprises:

• a first substrate;
• a first conducting layer disposed on the first substrate;
• a first insulating layer disposed on the first conducting layer and comprising a first opening disposed in the peripheral region;
• a second conducting layer disposed on the first conducting layer, wherein the second conducting layer comprises a first conductive portion, and the first conductive portion is electrically connected to the first conducting layer through the first opening;
• a second insulating layer disposed on the first insulating layer and comprising a plurality of first protruding structures disposed in the peripheral region and being defined by only material of the second insulating layer protruding from a surface of the first insulating layer;
• a sealant layer disposed in the peripheral region and on the second insulating layer and on the first insulating layer, a maximum thickness of the sealant layer measured from the surface of the first insulating layer being greater than a height of plurality of first protruding structures measured from the surface of first insulating layer,
• wherein the plurality of the first protruding structures comprises a first protruding pattern and a second protruding pattern, at least a portion of the first protruding pattern extends along a first direction, and at least a portion of the second protruding pattern extends along a first direction,
• wherein the first conductive portion is disposed between the first protruding pattern and the second protruding pattern along a second direction, and the second direction is a radial direction extending outwardly from the active region and perpendicularly to the first direction,
• wherein, in a cross-sectional view, a side surface and a top surface of the first protruding pattern are directly in contact with the sealant layer and a side surface and a top surface of the second protruding pattern are directly in contact with the sealant layer, and
• wherein the first opening is disposed between the first protruding pattern and the second protruding pattern along the second direction, and the first conductive portion is spaced apart from the first protruding pattern and spaced apart from the second protruding pattern.
