POLLUTION PREVENTION TYPE ANTI-REFLECTION FILM AND DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a pollution prevention type anti-reflection film which is resistant to falling by surface friction such as wiping and excellent in durability and can make its anti-pollution and anti-reflection performance continue for a long time by obtaining a pollution preventing film excellent in abrasion resistance while using the merits of the pollution preventing film by a thing having the structure of a fluoroalkyl ether and a display.

SOLUTION: A pollution preventing layer (2) having the structure of the fluoroalkyl ether is formed on the surface of an inorganic anti-reflection layer (1) which has a silicon dioxide-based inorganic layer (13) on the surface and the reflection factor of 2.0% or below of light 550 nm in wavelength. The pollution preventing layer has a pure water contact angle of at least 100° and adhesive tape adhesive force of at most 1.0 N/20 mm. The reduction rate of the pure water contact angle of the surface after 500 times of reciprocating friction by absorbent cotton under a load of 5.0 N/25 mm ϕ is 10% or below. In the display, the pollution prevention type anti-reflection film (3) of the thing 2.0 N/20 mm or below in adhesive tape adhesive force and the anti-reflection film are formed on the surface on the side of visual recognition.
