Abstract

The present invention provides a touch-type anti-glare film for display, having excellent blackness and sense of touch, and a polarizing plate and an image display device comprising the same.

Description

technical field [0001] The present invention relates to an anti-glare film, a polarizing plate and an image display device including the anti-glare film. In particular, the present invention provides an antiglare film for a touch display, a polarizing plate including the antiglare film for a touch display, and an image display device, the antiglare film having good blackness and touch feel. Background technique [0002] The function of the anti-glare film is to reduce reflection of external light by diffuse reflection through its surface protrusions, and the anti-glare film has been used in various display panels such as liquid crystal display (LCD), plasma display panel (PDP), cathode ray tube (CRT) and electroluminescence (EL) display) for preventing a decrease in contrast due to reflection of external light or preventing deterioration of visibility of the display due to reflection of an image. [0003] Among conventional anti-glare films, an anti-glare film having sever...
