Abstract

The invention provides a backlight module and a liquid crystal display. The backlight module comprises a backboard (11), a reflector plate (12), a light guide plate (13), and an optical film group (14). In the optical film group (14), the edge of an optical film (141) on the top is provided with a plurality of projections (142) extending outward. The backboard (11) comprises a bottom board (111), and a side plate (112). The side plate (112) is provided with a plurality of holes (113). The plurality of projections (142) respectively insert into the plurality of holes (113). The backlight module realizes a narrow frame, and prevents glue from leaking in gaps between the optical film group and the backboard when using a side edge glue dispensing method to fix the backlight module and a liquid crystal panel, thereby ensuring display effect and reliability of the liquid crystal display. The liquid crystal display is provided with the backlight module, and realizes a narrow frame, and prevents glue from leaking in gaps between the optical film group and the backboard, so the liquid crystal display has good display effect and reliability.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a liquid crystal display. Background technique [0002] Liquid crystal display (LiquidCrystalDisplay, LCD) has many advantages such as thin body, power saving, no radiation, and has been widely used, such as: mobile phone, personal digital assistant (PDA), digital camera, computer screen or notebook computer screen, etc. . [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a housing, a liquid crystal panel disposed in the housing, and a backlight module disposed in the housing. The structure of a traditional liquid crystal panel is composed of a color filter substrate (ColorFilterSubstrate), a thin film transistor array substrate (ThinFilmTransistorArraySubstrate, TFTArraySubstrate), and a liquid crystal layer (LiquidCrystalLayer) arranged between the two substrates.
