Electronic device
An electronic device is provided. The electronic device includes a substrate, a semiconductor unit, a wall, and a light-transmitting member. The semiconductor unit is mounted on the substrate. The wall is disposed on the substrate and surrounds the semiconductor unit. The wall includes two exterior wall components and two interior wall components. The two exterior wall components are spaced apart from each other, so that two gaps are formed between the two exterior wall components. The two gaps are in spatial communication with an installation area that is surrounded by the two exterior wall components. The two interior wall components are arranged in the installation area and spaced apart from each other. The two interior wall components correspond in position to the two gaps and respectively shade parts of the two gaps. The light-transmitting member is disposed on the wall and covered on the semiconductor unit.
