Antiglare film process for producing the same, and display device using antiglare film

Abstract

Disclosed is an antiglare film having excellent durability. The antiglare film is disposed on the front of a display device and comprises a transparent plastic film and, formed on the transparent plastic film, at least an antiglare layer having fine concaves and convexes on its surface, wherein the antiglare layer is formed of a transparent resin and satisfies requirements that: (1) the surface of the antiglare layer has a three-dimensional ten-point mean roughness of 0.9 μm to 3 μm; and (2) the mean spacing between adjacent profile peaks on a three-dimensional roughness reference plane is 20 μm to 50 μm.

1 . An antiglare film to be disposed on a front of a display device, said antiglare film comprising: 
 a transparent plastic film and an antiglare layer, the antiglare layer being formed on a surface of the transparent plastic film, the antiglare layer having fine concaves and convexes on its surface, wherein said antiglare layer is formed of a transparent resin and satisfies requirements that:    (1) the surface of the antiglare layer has a three-dimensional ten-point mean roughness of 0.9 μm to 3 μm; and    (2) the mean spacing between adjacent profile peaks on a three-dimensional roughness reference plane is 20 μm to 50 μm.    
   
   
       2 . The antiglare film according to  claim 1 , which has a total light transmittance of not less than 87% and a haze of 5 to 40.  
   
   
       3 . The antiglare film according to  claim 1 , wherein the transparent resin is a cured product of an ionizing radiation-curable resin.  
   
   
       4 . The antiglare film according to  claim 1 , which further comprises a primer layer to be formed between the transparent plastic film and the antiglare layer.  
   
   
       5 . The antiglare film according to  claim 4 , wherein the primer layer comprises transparent fine particles.  
   
   
       6 . A polarizing plate comprising the antiglare film according to  claim 1 .  
   
   
       7 . A display device comprising the polarizing plate according to  claim 6  disposed on the front of a display.  
   
   
       8 . A liquid crystal panel for a display device, comprising: two polarizing plates, the liquid crystal display cell being sandwiched between the two polarizing plates, at least one of the polarizing plates being the polarizing plate according to  claim 6 .  
   
   
       9 . A display device comprising the liquid crystal panel according to  claim 8  and a surface light source device disposed on the underside of the liquid crystal panel.  
   
   
       10 . A display device comprising the antiglare film according to  claim 1  disposed on the front of a display.  
   
   
       11 . A display device comprising a touch panel and the antiglare film according to  claim 1  formed in that order on the front of a display.
