Abstract
A backlight module provides light to a display panel and includes a bottom board, a support frame, first and second magnetic members, a light guide device, and a light source. The support frame is connected to the bottom board to contain the light guide device. The light source is disposed on the bottom board corresponding to a light entrance surface of the light guide device. Light of the light source is incident into the light guide device via the light entrance surface and emitted to the display panel from a light exit surface of the light guide device. The first magnetic member is disposed on the support frame or the light guide device corresponding to the light source. The second magnetic member is disposed corresponding to the first magnetic member to generate a magnetic force for driving the light entrance surface to be aligned with the light source.
