Anti-reflector film, and a display provided with the same

摘要

An anti-reflection film is in the form of a laminated film composed of an uppermost film layer containing coloring matter having an absorbing peak in a region near the infrared region of 700 nm-900 nm, or coloring matter having an absorbing peak in a region of 600 nm-700 nm, or both of the above coloring matter, and the next film layer to the uppermost layer containing coloring matter having an absorbing peak in a region of 500 nm-600 nm. The anti-reflection film utilizes a variation of the refractive indexes based on abnormal refractive index dispersion by the films containing the coloring matter. The anti-reflection film having a low reflectivity all over the visible light region can be manufactured by utilizing the abnormal refractive index dispersion of the next layer to the uppermost layer caused by an absorption of red coloring matter and a balance with the refractive indexes of the uppermost layer containing red color matter having an absorption in the region near the infrared wavelength, or blue coloring matter, or both of the above coloring matter. Furthermore, red coloring matter, having an absorbing peak in the region of 500 nm-600 nm and contained in the next layer to the uppermost layer, absorbs side bands of green and red, and accordingly, color purity is improved.
