The present disclosure provides an electronic device including a first substrate, a plurality of sub-pixels, a first integrated circuit chip, a plurality of sub-sensor units, and a second integrated circuit chip. The first substrate has a surface, and the surface has a normal direction. The sub-pixels are disposed on the first substrate. The first integrated circuit chip is disposed on the first substrate and electrically connected to the sub-pixels. The sub-sensor units are disposed on the first substrate. The second integrated circuit chip is disposed on the first substrate and electrically connected to the sub-sensor units. A gap is included between two adjacent ones of the sub-pixels, and at least a portion of one of the sub-sensor units is overlapped with the gap along the normal direction.
