Problems solved by technology

But there is a problem with this structure, that is, it is difficult to fix the backlight module and the LCD panel 300' after removing the word glue and the frame is too narrow
[0007] to solve figure 2 As shown in the structure of the backlight module, the prior art generally adopts the following image 3 The method of dispensing glue on the side of the back plate 400 as shown fixes the back plate 400 and the liquid crystal panel 300 ′, but this method easily causes the glue 500 to leak inward from the contact surface of the back plate 400 and the liquid crystal panel 300 ′ to the display. area, and the risk of degumming is greater

Abstract

The invention provides a backlight module and a liquid crystal display device. The backlight module comprises a back plate (1). The back plate (1) comprises a bottom plate (101), a side plate (103) perpendicularly connected to the bottom plate (101) from the peripheral edge of the bottom plate (101), and a top plate (105) arranged on the periphery of the side plate (103) and perpendicularly connected to the side plate (103) at the end, away from the bottom plate (101), of the side plate (103). The top plate (105) is provided with a plurality of glue containing holes (1051) used for containing glue so that a liquid crystal panel can be fixed to the back plate (10), and the problems of glue leakage, glue disengagement and the like in the assembling process of the backlight module and the liquid crystal panel can be solved under the premise that square glue is not used for achieving the narrow frame of the liquid crystal display device.

Description

Technical field [0001] The present invention relates to the field of liquid crystal display technology, in particular to a backlight module and a liquid crystal display device. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as: mobile phones, personal digital assistants (PDA), digital cameras, computer screens or laptop screens, etc. . [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal panel and a backlight module. Generally, the structure of a liquid crystal panel is composed of a color filter substrate (ColorFilter), a thin film transistor array substrate (ThinFilmTransistorArraySubstrate, TFTArraySubstrate), and a liquid crystal layer (LiquidCrystalLayer) disposed between the two substrates. The working principle is A driving voltage is applied to the two glass sub...
