Embodiment Construction

[0023] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0024] The present invention firstly provides a color filter substrate, such as figure 1 As shown, the color filter substrate 1 includes a first color filter layer 11 and a second color filter layer 12 respectively located on both sides thereof, and the arrangement of the color-resist blocks in the second color filter layer 12 is the same as that of the first color filter layer. The arrangement of the color resist blocks in the optical layer 11 is the same.

[0025] refer to figure 1 In the optical path indicated by the arrow in the middle, generally, the function of the first color filter layer 11 is the same as that of the color filter layer in a conventiona...

Abstract

The invention discloses a color film substrate, a display panel and a display device. The color film substrate comprises a first color filtering layer and a second color filtering layer which are located on two sides of a substrate body, and the array manner of color resistance blocks of the second color filtering layer is consistent with that of the first color filtering layer. Since one color filtering layer is arranged on the lighting emitting side of the color film substrate, the light absorption feature of the color filtering layer is utilized, the light emitted at a large angle is absorbed, the visible angle of the display panel is controlled in a narrow range, and the peep-proof function is realized. Compared with the prior art, the color film substrate has the advantages that the brightness of the front surface of the display panel is not affected, and the color gamut of the display panel can be increased by stacking the two color filtering layers.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a color filter substrate, a display panel and a display device. Background technique [0002] The existing peep-proof display device is realized by adding a peep-proof film on the display screen. The traditional anti-spy film adopts the patented technology of microlouver optical technology, so that the picture displayed on the screen is only for the user to read from the front, and anyone can only see the dark picture from the sides. [0003] The above-mentioned anti-peeping display device usually has a viewing angle range of about 60°, that is to say, when viewed from the left, the image is invisible beyond 30° from the left edge of the screen, and when viewed from the right, the image is invisible beyond 30° from the right edge of the screen. The main problem of this traditional anti-peeping film is: while realizing the anti-peeping function, the brightness of the fro...
