Abstract
A display apparatus is provided. A display unit has a display region. A protecting cover has a patterned region, wherein the patterned region does not overlap the display region. A light guide plate is disposed between the display unit and the protecting cover and has a first light scattering region and a second light scattering region. The first light scattering region at least partially overlaps the display region, and the second light scattering region at least partially overlaps the patterned region. A light emitting unit emits a light beam to the light guide plate. After the light beam enters the light guide plate, a part of the light beam is scattered to the display region by the first light scattering region and another part of the light beam is scattered to the patterned region by the second light scattering region.
