Problems solved by technology

However, due to the filtering effect of the color filter layer on the color filter substrate, it is not conducive to the improvement of the light transmittance of the liquid crystal display. In addition, the manufacturing process of the color filter layer on the color filter substrate is relatively cumbersome, and the cost is difficult to reduce

Abstract

The invention provides to a light guide plate, a backlight source and a display device. The light guide plate comprises a light guide area. The light guide plate also comprises light filtering areas which are located at one side of a light-entering surface of the light guide plate; the light filtering areas at least comprise a first color light filtering area used for transmitting light of a first color, a second color light filtering area used for transmitting light of a second color, and a third color light filtering area used for transmitting light of a third color. According to the light guide plate, the backlight source and the display device of the invention, the light filtering areas are arranged on the light guide plate, so that a color light filtering layer is not required to be formed on a color film substrate of a liquid crystal display, and a black matrix used for shading light is only required to be arranged on the color film substrate, and a pixel area formed by the black matrix is set to be in a transparent state, and therefore, a display effect the same with the display effect of a color film substrate in the prior art can be realized; and the color light filtering layer is not required to be formed on the color film substrate, and therefore, compared with the prior art, the light transmittance rate of the liquid crystal display can be improved, and the production process of the display can be simplified.

Description

technical field [0001] The invention relates to the display field, in particular to a light guide plate, a backlight source and a display device. Background technique [0002] Liquid crystal displays dominate the current flat-panel display market due to their small size, low power consumption, relatively low manufacturing cost, and no radiation. [0003] The main structure of a traditional liquid crystal display includes a backlight source and a liquid crystal module. The liquid crystal module mainly includes an array substrate formed by a pair of boxes, a color filter substrate, and a liquid crystal layer between the array substrate and the color filter substrate. The pixel electrode and the common electrode are respectively formed on the substrate and the color filter substrate, and an electric field is formed between the two electrodes after power is applied. By controlling the change of the electric field intensity, the rotation angle of the liquid crystal molecules can ...
