Abstract: An illumination device includes a housing, a first light-emitting element, a second light-emitting element, a substrate, and a reflector. The housing has a first light-outlet portion and a second light-outlet portion separated from each other. The first light-emitting element is disposed in the housing and suitable for emitting a first beam. The second light-emitting element is disposed in the housing and suitable for emitting a second beam emitted from the second light-outlet portion. The substrate is disposed in the housing and electrically connected to the first light-emitting element and the second light-emitting element. The reflector is disposed in the housing and located on a transmission path of the first beam. The reflector is suitable for reflecting the first beam to the first light-outlet portion.

Abstract: The invention provides a display device including a panel module, a reflection module and a light guide module. The panel module has a display area for displaying an image and a perspective area for displaying a background. The reflection module is disposed at a side of the panel module. A reflective sheet on the reflection module faces the panel module. The shape and position of the reflective sheet correspond to the shape and position of the display area, respectively. The light guide module includes a light guide plate and a light source. The light guide module is disposed between the panel module and the reflection module. The light guide plate has a plurality of optical microstructures, and light emitted by the light source is at least partially directed away from the panel module by the optical microstructures and is transmitted to the reflection module.
