Abstract
An electronic device includes a reflective panel, a light guide plate and a light source. The light guide plate is disposed on the reflective panel, and the light guide plate has a first surface adjacent to the reflective panel, a second surface and a side surface connected between the first surface and the second surface. The light source is adjacent to the side surface of the light guide plate. When light emitted from the light source passes through the light guide plate, a first light shape diagram is obtained by performing measurement on the first surface, a second light shape diagram is obtained by performing measurement on the second surface, the first light shape diagram has a first maximum brightness, the second light shape diagram has a second maximum brightness, and the first maximum brightness is greater than the second maximum brightness.
