DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] A full-viewing angle display screen with a built-in shielding layer, referring to Figure 1 , including a display screen body 10, the display screen body 10 includes an upper display layer 20 and a lower display layer 30 located on one side of the upper display layer 20. The upper display layer 20 includes an upper polarizer 21, an upper glass 22 and an upper electrode layer 23 arranged in sequence from top to bottom, the lower display layer 30 includes a lower polarizer 31, a lower glass 32 and a lower electrode layer 33 arranged in sequence from bottom to top, and a liquid crystal layer 40 is arranged between the upper electrode layer 23 and the lower electrode layer 33, and the liquid crystal layer 40 is composed of a plurality of liquid crystal molecules. When the upper display layer 20 and the lower display layer 30 are formed into a box, the liquid crystal layer 40 forms a deflection electric field with the upper electrode layer 23 and the lower electrode layer 33, converting the electrical signal into an image, so that the display screen body 10 has a display function.

[0025] Further, refer to Figure 1 The lower electrode layer 33 includes a positive electrode 331 and a negative electrode 332 . When the upper electrode layer 23 and the lower electrode layer 33 are powered on, the liquid crystal layer 40 is horizontally flipped between the upper electrode layer 23 and the lower electrode layer 33 .

[0026] Reference Figure 1 A shielding electrode layer 50 is disposed between the upper display layer 20 and the lower display layer 30 . The shielding electrode layer 50 is located between the upper glass 22 and the upper electrode layer 23 . The shielding electrode layer 50 is used to reduce interference of the electrode on the display screen body 10 .

[0027] Reference Figure 1 The shielding electrode layer 50 is arranged in an interval etching manner, and the interval etching shielding electrode layer 50 is arranged between the upper glass 22 and the upper electrode layer 23, so as not to destroy the deflection electric field between the liquid crystal layer 40 and the upper electrode layer 23 and the lower electrode layer 33, so that the equipotential surface is not formed where the liquid crystal layer 40 is close to the shielding electrode layer 50, so as not to affect the deflection of the liquid crystal molecules. By arranging the shielding electrode layer 50 in the box of the upper glass 22 and the lower glass 32, the deflection electric field of the liquid crystal layer 40 is not affected and no additional production process is required.

[0028] Reference Figure 1 , an upper color filter 60 is provided on the side of the upper display layer 20 away from the lower display layer 30, and the upper color filter 60 is located on the upper surface of the upper polarizer 21. A lower color filter 70 is provided on the side of the lower display layer 30 away from the upper display layer 20, and the lower color filter 70 is located on the lower surface of the lower polarizer 31. The upper color filter 60 and the lower color filter 70 sandwich the display screen body 10, so that the visual effect of the display screen body 10 presents a high-definition, high-resolution and high-brightness display.

[0029] Further, refer to Figure 1 and Figure 2 The upper color filter 60 and the lower color filter 70 are both composed of a color filter substrate 61 and a blue light absorption layer 62 arranged on the color filter substrate 61. The blue light absorption layer 62 is arranged on the color filter substrate 61 by coating, so that the upper color filter 60 and the lower color filter 70 have the effect of preventing blue light.

[0030] Reference Figure 1 An anti-glare protective film 80 is provided on the side of the lower color filter 70 away from the lower polarizer 31. The anti-glare protective film 80 is attached to the lower surface of the lower color filter 70. The anti-glare protective film 80 can reduce the reflection of light and play an anti-reflection role.
