Electronic device
An electronic device includes a first substrate, 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 first substrate includes a surface. The first protrusion is in the first region. A maximum distance from the surface to a top surface of the first protrusion is defined as a first distance. The second protrusion is in the second region. A maximum distance from the surface to a top surface of the second protrusion is defined as a second distance. The first protrusion is disposed between two of the third protrusions. A maximum distance from the surface to a top surface of the third protrusion is defined as a third distance. The first distance is different from the second distance, and the third distance is less than the first distance.
