Embodiment Construction

[0020] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] In the embodiment of the present invention, by placing the polarizing layer in the color filter substrate on the light-incident side, and adding a red color conversion layer and a green color conversion layer on the light-incident side of the red filter layer and the green filter layer respectively, and the blue The vacancy in the color light output area is filled by the planarization layer, so that the incident blue light is conv...

Abstract

The invention discloses a color film substrate, a production method of the color film substrate, and a display device. The color film substrate is mainly characterized in that a polarization layer in the color film substrate is arranged at a light-entering side; a red color conversion layer and a green color conversion layer are additionally arranged on light-entering sides of a red filter layer and a green filter layer respectively; a blue light-exiting area is hollow and is filled with a planarization and layering manner, so that entering blue light can be converted into red light or green light as required; by virtue of a conventional red or green filter layer, the light brightness loss can be reduced to the greatest extent; and the low-power-consumption color display is achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a color filter substrate, a preparation method thereof, and a display device. Background technique [0002] In a traditional liquid crystal display device, from top to bottom, it mainly includes: a color filter substrate, a liquid crystal layer, a TFT (Thin Film Transistor, thin film transistor) array substrate, and a backlight source. Among them, the backlight source is set as a white backlight (that is, the light incident on the TFT array substrate is white light), the color filter substrate, the liquid crystal layer, and the TFT array substrate together form a "liquid crystal cell" with a light valve, and the outside of the color filter substrate and the TFT Polarizers are installed on the outside of the array substrate. By adjusting the TFT switch, a voltage is applied to the color filter substrate and the TFT array substrate to rotate the liquid crystal layer, and the light...
