Abstract
A backlight module comprises a reflector, an optical element, and a supporting structure. The supporting structure is disposed on the reflector and contacting the optical element for restricting the optical element from deformation. The supporting structure comprises a supporting portion and a cushion. The cushion is disposed between the supporting portion and the reflector. The cushion is an elastic element, providing a plurality of supporting forces in at least two directions, and enabling a tip of the supporting portion to move with the optical element.
