Anti-reflective film and production method thereof |
摘要 |
The present invention provides an anti-reflective film that prevents wavelength dispersion from being applied to light transmitted through an anti-reflective film. The present invention is an anti-reflective film, which reduces reflection of visible light on a surface of a substrate by being mounted on the substrate, has a wavelength dispersion structure for applying first wavelength dispersion to visible light transmitting through the anti-reflective film, and contains a wavelength dispersion material for applying second wavelength dispersion to the visible light transmitting through the anti-reflective film, wherein visible light transmitted through the anti-reflective film has flat transmission wavelength dispersion in a visible light region. |

1. An anti-reflective film, which reduces reflection of visible light on a surface of a substrate by being mounted on the substrate, comprising:
an uneven part including a plurality of projections; a base part; wherein a pitch between tops of adjacent projections of the plurality of projections is a visible light wavelength or shorter; a rate of a height h from the top to the bottom point of a projection to the pitch p between the tops of adjacent projections of the plurality of projections is 0.5<h/p<2.0; wherein the uneven part is a wavelength dispersion structure for applying first wavelength dispersion to visible light transmitting through the anti-reflective film, the anti-reflective film comprises a wavelength dispersion material for applying second wavelength dispersion to the visible light transmitting through the anti-reflective film, the wavelength dispersion material includes a visible light polymerizing agent having a transmittance that increases from a short wavelength side to a long wavelength side, and visible light transmitted through the anti-reflective film has flat transmission wavelength dispersion in a visible light region.
