Electronic device

Abstract

An electronic device includes a first substrate, a driving element, a first protrusion, a second protrusion and a plurality of third protrusions. The first substrate includes an edge, a first region, and a second region. The second region is disposed between the edge and the first region. The driving element is disposed in the first region. The first protrusion is disposed on the first substrate in the first region, and has a first thickness. The second protrusion is disposed on the first substrate in the second region, and has a second thickness. The third protrusions are disposed on the first substrate. The first protrusion is disposed between two of the third protrusions. At least one of the third protrusions has a third thickness. The first thickness is different from the second thickness, and the third thickness is less than the first thickness.
