Problems solved by technology

[0004] Based on the above description, it can be seen that the omission of the lower polarizer 201 may cause the external ambient light to be re-reflected to the light-emitting side of the liquid crystal display panel 10 after entering the liquid crystal display panel 10 and then emitted, which will cause local strong light reflection, which causes strong glare, and especially seriously reduces the outdoor readability of the liquid crystal display device

Abstract

The embodiment of the invention provides a liquid crystal display device, and relates to the technical field of display. The reflection of environment light can be weakened, so that the outdoor readability of the liquid crystal display device can be improved. The liquid crystal display device comprises a liquid crystal display panel, a polarizing back light module and a polaroid, wherein the polaroid is positioned at one side, backing from the polarizing back light module, of the liquid crystal display panel, and the polarizing back light module comprises a reflecting plate and a 1 / 4 phase difference film positioned at one side, near the liquid crystal display panel, of the reflecting plate, wherein a 45-degree included angle is formed between an optical axis of the 1 / 4 phase difference film and a transmission axis of the polaroid. The liquid crystal display device is used for the display device manufacturing.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display device. Background technique [0002] The lightness and thinness of a liquid crystal display (Liquid Crystal Display, LCD for short) makes it widely used in various fields. The structure of a traditional liquid crystal display device is shown in FIG. A polarizer 202 , and a backlight module 30 ; wherein, the backlight module 30 may include a light source 301 , a reflection plate 302 , a light guide plate 303 and an optical film 304 . In this case, as shown in Figure 1(b), when external ambient light enters the liquid crystal display device, it can form linearly polarized light through the polarization of the upper polarizer 202, and the linearly polarized light The polarization direction is consistent with the transmission axis direction of the upper polarizer 202; when the linearly polarized light passes through the liquid crystal display panel 10 and...
