Abstract: An electronic device includes a substrate, a light-emitting element, and a spacing structure. The light-emitting element is disposed on the substrate. The spacing structure is disposed adjacent to the light-emitting element, and the spacing structure includes a first wall, a second wall, and a boundary portion. The first wall includes a first protrusion portion and extends in a first direction. The second wall includes a second protrusion portion and extends in a second direction, and the first direction is different from the second direction. The boundary portion is connected to the first protrusion portion and the second protrusion portion, and the height of the boundary portion is lower than the height of the first protrusion portion.
