Abstract
A backlight module includes: a frame; a backboard configured to support the frame; a radiator provided in the backboard and connected to an inner wall of the frame; a light source fixed to an inner wall of the radiator; a light guide plate relatively slidably mounted on the radiator and configured to guide light emitted by the light source; and at least one buffer mounted on the radiator and configured so that the radiator is moveable relative to the backboard against an elastic force of the buffer. The backlight module can effectively eliminate the phenomenon in which a shadow of the light source is present in pictures coming from the backlight module since the light guide plate presses against the light source after it is heated to expand. The present invention further provides a display device including the above backlight module.
