ANTIREFLECTIVE FILM AND METHOD OF MAKING SAID FILM Russian patent published in 2013 - IPC G02B1/11 G02B5/02 

FIELD: physics.

SUBSTANCE: antireflective film which reduces reflection of visible light on the surface of a substrate has a wavelength dispersion structure for causing a first wavelength dispersion of visible light passing through said antireflective film, and contains wavelength dispersion material for causing a second wavelength dispersion of visible light passing through said antireflective film. Visible light in the range from 380 nm to 780 nm, passed through the antireflective film, has light transmission fluctuation which is less than 0.5% of the transmission value at wavelength of 550 nm. The method of making the film involves depositing a visible light-cured resin onto the substrate which has a UV absorbing component in order to form a film; forming a rough part on the surface of the film, having a plurality of protrusions; the space between peaks of neighbouring protrusions is equal to or less than the wavelength of visible light; irradiating the film with visible light on the side of the substrate and curing the film to form an antireflective film.

EFFECT: preventing wavelength dispersion of light passing through the antireflective film, which creates a display colouring which is different from the colour of the display itself.
