[0001] The present disclosure relates to a light conversion film and a light conversion device including the same. Background technique
[0002] Generally, fluorescent substances are luminescent materials that emit light with a unique wavelength by absorbing energy in the form of light or electricity from the outside, and can be divided into inorganic fluorescent substances, organic fluorescent dyes, nano Crystal fluorescent substances, etc.
[0003] Recently, various attempts have been made to change the spectrum of the light source using such fluorescent substances. This involves fluorescent substances absorbing light of some specific wavelengths emitted from a light source, converting these lights into light with longer wavelengths in the visible light region and emitting the light, and depending on the light-emitting characteristics of the fluorescent substance, the emitted light can be greatly improved. Light brightness, color purity, color gamut, etc....
