Abstract

The invention relates to a liquid crystal display device, which comprises a liquid crystal display panel, a backlight module and a first framework. The first framework contains and fixes the backlight module, and includes two opposite sides, each of which comprises an extension sheet extending towards the inside of the first framework. The backlight module and the liquid crystal display panel are arranged overlappedly, and include a second framework which comprises two side walls facing each other and corresponding to the sides of the first framework, and each side wall is provided with a slide groove. The extension sheets are contained in the slide grooves of the second framework. No matter whether discrepancy exists between actual sizes and design sizes of the two frameworks, the structure can still realize firm matching of the backlight module and the first framework, and the liquid crystal display device can be firmer and more reliable after the assembly.

Description

technical field [0001] The invention relates to a liquid crystal display device. Background technique [0002] In recent years, liquid crystal display devices have gradually occupied the mainstream of display products and gradually replaced traditional cathode ray tube displays due to the advantages of light and thin volume, small space occupation, and low radiation. A liquid crystal display device usually includes a side light source, such as a backlight module, to provide a plane light with sufficient brightness and uniformity for its liquid crystal display panel. [0003] see figure 1 , is a three-dimensional exploded schematic diagram of a liquid crystal display device in the prior art. The liquid crystal display device 1 includes a liquid crystal display panel 11 and a backlight module 10 stacked with the liquid crystal display panel 11 . The backlight module 10 provides uniform planar light for the liquid crystal display panel 11 . The liquid crystal display device...
