Anti-glare and anti-reflection film, polarizer and display panel

A polarizer, comprising:

• a polarized body;
• and
• an anti-glare and anti-reflection film formed on the polarized body;
• wherein the anti-glare and anti-reflection film comprises:
• a hardened layer;
• first extinction particles dispersed in the hardened layer;
• and
• second extinction particles dispersed in the hardened layer;
• wherein the first extinction particles comprise a particle core, a first coating covering the particle core, and a second coating covering the first coating, and the first coating has a refractive index different from that of the second coating;
• and
• wherein a mass percentage of the first extinction particles is greater than 80% of a total mass of the first extinction particles and the second extinction particles.

A display panel comprising:

• a display substrate;
• and
• a polarizer;
• wherein the polarizer comprises a polarized body and an anti-glare and anti-reflection film formed on the polarized body;
• wherein the anti-glare and anti-reflection film comprises:
• a hardened layer;
• first extinction particles dispersed in the hardened layer;
• and
• second extinction particles dispersed in the hardened layer;
• wherein the first extinction particles comprise a particle core, a first coating covering the particle core, and a second coating covering the first coating, and the first coating has a refractive index different from that of the second coating;
• and
• wherein a mass percentage of the first extinction particles is greater than 80% of a total mass of the first extinction particles and the second extinction particles.
