Abstract

A light guide plate includes a light guide layer and a metal reflective layer. The light guide layer has a light emitting surface, a bottom surface and a light incident surface. The light incident surface is located between the light emitting surface and the bottom surface. The metal reflective layer is coated on the bottom surface of the light guide layer. Additionally, an average reflectance of the metal reflective layer for light in a wavelength range of 400 to 550 nanometers is greater than an average reflectance of the metal reflective layer for light in a wavelength range of 550 to 700 nanometers.

Description

technical field [0001] The invention relates to a light guide plate and a backlight module comprising the light guide plate, in particular to a light guide plate with a metal reflection layer and a backlight module comprising the light guide plate. Background technique [0002] With the development of technology, liquid crystal display devices have been widely used in various electronic products such as notebook computers, digital cameras, and mobile phones. Since the liquid crystal display panel of the liquid crystal display device does not have luminous properties, the liquid crystal display device needs to include a side light source, such as a backlight module, to provide sufficient and uniform light. According to the configuration of different positions of the backlight source, the backlight module can be divided into an edge-type backlight module and a direct-type backlight module. Generally speaking, an edge-lit backlight module includes a light guide plate, a reflec...
