Abstract

The embodiment of the invention discloses a backlight module and a liquid crystal display device, which relate to the field of the liquid crystal display, and can effectively reduce the overall weight of the liquid crystal display device. The backlight module comprises a rear panel and a light source which is arranged on one side of the rear panel, and the backlight module also comprises a reflection sheet which is arranged on the rear panel and an optical membrane material which is arranged above the reflection sheet, an optical cavity is formed between the reflection sheet and the optical membrane material, the reflection sheet is provided with a plurality of micro structure projections, and the distribution density of the micro structure projections on the reflection sheet is gradually reduced along the direction of the light source.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a backlight module and a liquid crystal display device. Background technique [0002] With the advancement of technology, LCDs are becoming lighter and thinner. In the prior art, the light guide plate is an important optical element of the liquid crystal display, and it forms a backlight system with other optical elements such as light source, reflector plate, diffuser plate and prism plate, and its function is to guide the light emitted by the point light source or the line light source from The output surface is emitted, and the luminance of the panel and the uniformity of the luminance are improved at the same time. [0003] During the research process, the inventor found that the prior art has at least the following problems: because the light guide plate occupies a considerable weight and volume of the liquid crystal display, it is difficult to reduce the total weight ...
