Abstract

The ultraviolet curable resin composition for blue light filter film of the present invention contains: at least one polymerizable liquid crystal compound having a polymerizable functional group; base) acrylate. Moreover, the blue light filter film of this invention is equipped with the cured film which hardened the said ultraviolet curable resin composition on this support body, and a support body.

Description

technical field [0001] The invention relates to an ultraviolet curable resin composition for a blue light filter film and a blue light filter film using the composition, in particular to an ultraviolet curable resin composition for a blue light filter film and a blue light filter film using the composition. The above-mentioned ultraviolet curable resin composition for blue light filter has the function of sufficiently blocking the wavelength around 450 nm, and at the same time, can impart the function of suppressing the yellowish tint and haze of the transmitted light. Background technique [0002] It is pointed out that blue light emitted from a display device or the like places a heavy burden on the eyes and the body. The so-called blue light refers to blue light in the wavelength region of 380 to 495 nm, and has stronger energy than visible light. Therefore, when blue light reaches the retina without being absorbed by the cornea and lens, there is a fear of damaging the ...
