    Abstract: Disclosed is a backlight system of a liquid crystal display device. A light guide plate is provided on a frame. A quantum dot diaphragm is arranged above or below the light guide plate. An optical diaphragm set is arranged above the light guide plate or the quantum dot diaphragm. When the quantum dot diaphragm is cut, left and right sides or/and upper and lower sides thereof are left with margins which are processed into bending portions while the backlight system is manufactured. Useless areas are located on the margins. The margins are bent, and are configured to encase the light guide plate or the optical diaphragm set. Thus, an entire display panel has the quantum dot diaphragm which can achieve high-efficiency color gamut conversion while the display panel displays an image. An impact on image quality caused by the useless areas resulted from cutting of the quantum dot diaphragm can be avoided. The backlight system is simple in structure, and is easy to manufacture.
