Abstract
The disclosure provides an electronic device including a housing, a light-emitting element and a light diffusion structure. The housing includes a first light-transmitting hole and a second light-transmitting hole. The light-emitting element is disposed in the housing, and is aligned with the first light-transmitting hole. The light diffusion structure includes a first light diffusion layer and a second light diffusion layer. The first light diffusion layer is disposed between the housing and the light-emitting element, and comprises a first semi-transparent region and a first light-shielding region. The first semi-transparent region corresponds to the first light-transmitting hole, and the first light-shielding region surrounds the first semi-transparent region. The second light diffusion layer is disposed between the housing and the light-emitting element, and comprises a second semi-transparent region and a second light-shielding region. The second semi-transparent region corresponds to the second light-transmitting hole. The second light-shielding region surrounds the second semi-transparent region.
