Problems solved by technology

[0003] With the rapid development of the liquid crystal display industry, the application of various liquid crystal display panels continues to increase. At present, the viewing angle design of display devices on the market is mainly symmetrical, which is difficult to meet the requirements of asymmetrical viewing angles. Vehicle-mounted liquid crystal display devices are used in different The loading position and different angles of view, the visual effects and lighting parameters are quite different, and the display device is generally installed in the central control position of the vehicle. Compared with the driver's position, it is on the driver's side. When the driver observes the display device, the general angle of view is not Viewed from the front of the display device, it is easy to cause the resolution of the driver's perspective to be too low, so it greatly affects the driver's observation of the vehicle display device, and therefore directly affects the driver's driving safety.

Abstract

The invention provides a liquid crystal display device, comprising a backlight module and a display panel. The backlight module comprises an optical assembly and a bottom plate. The optical assembly comprises a reflection piece, a light guide plate, a scattering piece and a prismatic lens. The bottom plate comprises a bottom plate first side face facing the optical assembly and a bottom plate second side face facing away from the optical assembly. The display panel comprises a display panel upper surface facing away from the optical assembly and a display panel lower surface facing the opticalassembly. The optical assembly comprises an optical assembly bottom surface facing the bottom plate first side face, an optical assembly top surface facing the display panel and a plurality of optical assembly side faces perpendicular to the optical assembly bottom surface. The normal direction of the bottom plate second side face is parallel to the normal direction of the display panel lower surface, and the normal direction of the optical assembly top surface intersects the normal direction of the display panel lower surface. The liquid crystal display device can improve the driving safetyof the driver.
