In a backlight which arranges light emitting diodes on a side surface of a light guide plate, even when the light emitting diodes having a thickness larger than a thickness of the light guide plate are used, it is possible to manufacture the light guide plate with high accuracy by injection molding. In a liquid crystal display device having a backlight which radiates light to a liquid crystal panel, LEDs are mounted on the light guide plate formed on the backlight as a light emitting element, and an S-shaped inclined portion whose thickness is not changed is formed on the light guide plate from a light incident surface to a light emitting surface of the light guide plate. Since the thickness of the inclined portion is not changed, it is possible to make the pressure of resin flow at the time of performing injection molding uniform thus manufacturing the light guide plate with high accuracy.

The present invention provides a backlight of a liquid crystal display device having an inclination surface on a light guide plate and preventing a breakage of a liquid crystal panel, wherein light which leaks from the inclination surface is made to return to the light guide plate and the adhesiveness of the light guide plate and a flexible printed circuit board is increased. In a liquid crystal display device having a backlight which radiates light to a liquid crystal panel, LEDs are formed on a light guide plate formed on the backlight as light emitting elements. Between the plurality of light emitting elements, a projecting portion of the light guide plate is formed, and a reflection member is formed on an adhesive sheet which adheres a projection member and a flexible printed circuit board to each other. By arranging the reflective member and the cushion member close to an inclination surface, light from the inclination surface is made to return to a light guide plate side, and an external force from the outside can be alleviated by a cushion member.
