Embodiment 1

[0040] Further, see figure 2 , the color filter substrate 1 further includes a blue light absorbing film 14 , and the blue light absorbing film 14 is disposed between the first base substrate 11 and the color filter layer 13 . The blue light absorbing film 14 can effectively filter out high-energy short-wave blue light between 400nm and 450nm, while maintaining a high transmittance for light of other wavelengths, so the pattern synthesized by the color filter layer 13 passes through the Filtering can reduce or eliminate the damage caused by blue light to human eyes.

[0041] It should be noted that the first base substrate 11 is usually made of alkali-free glass, but it inevitably contains Na+, K+, Mg2+ plasma, and the blue light absorbing film 14 is used as the base of the color filter layer 13 to block the first substrate. The metal ions in the base substrate 11 diffuse into the color filter layer 13, further blocking the diffusion of the metal ions in the first base subst...

Embodiment 2

[0044] further combined Figure 4 , the blue light absorbing film 14 is disposed between the first base substrate 11 and the first polarizer 12, the blue light absorbing film 14 can effectively filter out the high-energy short-wave blue light between 400nm-450nm, while maintaining the Due to the high transmittance, the patterns synthesized by the color filter layer 13 are filtered when they reach human eyes, which can reduce or eliminate the damage caused by blue light to human eyes.

[0045] It should be noted that, in this embodiment, firstly, the material of the blue light absorbing film 14 is a transparent organic resin, which is hydrophobic and has excellent optical stability and thermal stability, and this material is used as the first base substrate 11 and The base layer between the first polarizers 12 can enhance the adhesion of the first polarizers 12, while protecting the triacetyl cellulose (TAC, Triacetyl Cellulose) inside the first polarizers 12, triacetyl cellulo...

Abstract

The invention is applicable to the technical field of display panels, and provides a color film substrate and a manufacturing method thereof. The color film substrate comprises a first underlayment substrate, a first polarizer, a color filter layer and a blue light absorption film. The first polarizer is arranged on the upper surface of the first underlayment substrate, the color filter layer is arranged on the side, away from the first polarizer, of the first underlayment substrate, and the blue light absorption film is arranged between the first substrate and the color filter layer, or the blue light absorption film is arranged between the first underlayment substrate and the first polarizer. According to the color film substrate in the embodiment, the blue light absorption film is arranged between the firstunderlayment substrate and the color filter layer, or the blue light absorption film is arranged between the first underlayment substrate and the first polarizer, and the blue light absorption film can effectively filter high-energy short-wave blue light between 400nm and 450nm, can keep a relatively high penetration rate for light with other wavelengths, and can weaken or eliminate the damage of blue light to human eyes.

Description

technical field [0001] The present application belongs to the technical field of display panels, and more specifically relates to a color filter substrate and a manufacturing method thereof. Background technique [0002] Various existing electronic display devices are generally called thin film transistor liquid crystal displays (TFT-LCD, ThinFilm Transistor-Liquid Crystal Display). TFT-LCD mainly includes an array substrate, a color filter substrate, and a liquid crystal layer (LCL, Liquid Crystal Layer) arranged between the two substrates. Its working principle is to control the liquid crystal molecules of the liquid crystal layer by applying a driving voltage on the two substrates. rotation. While the traditional display panel achieves color display, it transmits light of the full wavelength range of visible light, which cannot filter out the high-energy short-wave blue light that is harmful to humans. Among them, the high-energy short-wave blue light refers to the wavel...
