Abstract

The invention relates to a backlight module and a liquid crystal display device. The backlight module comprises a light guide plate, a base, a light source, a reflecting element and a reflector, the light guide plate is connected with the reflector through a double-faced adhesive tape, the double-faced adhesive tape is arranged on the edge of the bottom of the light guide plate, and the plane of the emergent light surface of the light source is arranged between the plane of the bottom of the light guide plate and the plane of the emergent light surface of the light guide plate. By changing the arrangement of the light guide plate and the reflector, the invention solves the technical problem that spots appear on a corresponding display panel.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a backlight module capable of eliminating light leakage from the bottom surface of a light guide plate and a liquid crystal display device. Background technique [0002] Liquid Crystal Displays (LCDs) have been widely used in various electronic products. Most of the LCDs are backlight LCDs, which include a liquid crystal display panel and a backlight module. The backlight module can be divided into side-light type and direct-light type according to the incident position of the light source, so as to provide backlight to the liquid crystal display panel. [0003] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of an existing side-light incident backlight module. Among them, 101 is a light guide plate, 102 is a light source, 103 is a reflective element, 104 is a reflective sheet, and the base is 105. It can be seen from the figure that due to the ex...
