Abstract

The present disclosure provides a display device comprising a display panel, wherein a first polarizer is arranged at a side of the display panel that is opposite to the side for displaying images, and a functional component with a grid structure and a second polarizer are arranged in sequence along the direction away from the display panel at the side for displaying images, the second polarizer being capable of scattering light rays that penetrate the second polarizer.

Claims

1. A display device comprising:

a display panel having a first side for displaying images;

a first polarizer arranged at a second side of the display panel that is opposite the first side for displaying images;

a functional component with a grid structure arranged at the first side of the display panel, wherein the functional component comprises a protective glass and a touch module comprising a touch sensing electrode arranged on the protective glass; and

a second polarizer arranged at a side of the functional component away from the display panel, the second polarizer being configured to scatter light rays that penetrate the second polarizer to reduce Moiré

profiling caused by interference between the display panel and the grid structure of the functional component;

wherein the second polarizer comprises a base and an anti-glare layer arranged on the base, the anti-glare layer is a resin layer including inner scattering particles and the scattering particles are polymetric hollow microspheres.

2. The display device according to claim 1, wherein the anti-glare layer has a thickness ranging from 6.4 μ

m to 18 μ

m.

3. The display device according to claim 2, wherein the anti-glare layer is provided with concave-convex microstructures on a surface thereof away from the base.

4. The display device according to claim 1, wherein the scattering particles have a particle diameter ranging from 2.4 μ

m to 6 μ

m.

5. The display device according to claim 4, wherein the anti-glare layer is provided with concave-convex microstructures on a surface of the anti-glare layer disposed away from the base.

6. The display device according to claim 1, wherein the scattering particles are made of at least one of acrylate copolymer and styrene copolymer.

7. The display device according to claim 6, wherein the anti-glare layer is provided with concave-convex microstructures on a surface of the anti-glare layer disposed away from the base.

8. The display device according to claim 1, wherein the anti-glare layer is provided with concave-convex microstructures on a surface of the anti-glare layer disposed away from the base.

9. The display device according to claim 1, wherein the touch sensing electrode is arranged at a side of the protective glass facing the display panel.

10. The display device according to claim 1, wherein the touch sensing electrode is arranged on a support layer, and the support layer is attached to the side of the protective glass facing the display panel.
