Abstract

The invention provides a light guide plate and a display device, and the light guide plate is characterized in that the light guide plate comprises a light guide plate body which is provided with a light outgoing surface; a micro-nano structure layer which is located on the light outgoing surface and / or the opposite side of the light outgoing surface, wherein a plurality of micro-nano structures are distributed on the micro-nano structure layer; a plurality of concave structures are distributed on the micro-nano structure layer, the concave structures are randomly arranged in the micro-nano structure area to which the concave structures belong, and convex structures are arranged in the concave structures. The display device comprises the light guide plate. The times of light reflection andrefraction are increased through the arrangement of the micro-nano structures and the convex structures so that the light is uniformly dispersed, and the emitted light is more uniform.

Description

【Technical field】 [0001] The present application relates to the technical field of light guide plates, in particular to a light guide plate and a display device. 【Background technique】 [0002] According to the development of the information society, the demand for various types of display devices for displaying images has increased. Recently, various display devices such as liquid crystal displays (LCDs), plasma display panels (PDPs), and organic light emitting diode (OLED) display devices have been utilized. [0003] The liquid crystal display device should have a backlight unit to supply light from the outside. The backlight unit may include subunits such as a light source, a light guide plate, a reflector, and an upper sheet, and may also include at least one frame or chassis as a supporting structure to support the sides and back of the display device. Among the components of the backlight unit, a light guide plate (LGP) is a planar part for uniformly guiding light fr...
