PRODUCTION METHOD OF COATING FILM, ANTI-REFLECTING FILM AND ITS PRODUCTION METHOD, POLARIZING PLATE USING THE ANTI-REFLECTING FILM, AND IMAGE DISPLAYING DEVICE USING THESE

Japanese Patent JP2006122889

A

To provide a high-productivity, high-quality anti-reflecting film.

In an anti-reflecting film production method, a coating liquid is applied onto a web W, which is supported by a backup roller 11 and travels continuously, by using a slot die to form at least one layer having a film thickness of ≤200 nm in a dried state and having a lower refractive index than that of the web. An edge lip on the downstream side in the web traveling direction has a land length in the web traveling direction ILO of 30-100 μm, and a space between an edge lip 18a on the upstream side in the web traveling direction and a web surface is set so as to be 30-120 μm larger than a space between the edge lip 18b on the downstream side in the web traveling direction and the web surface.
