Abstract
The invention described in the present specification relates to a color conversion film including a resin matrix; and an organic fluorescent substance dispersed in the resin matrix, wherein the organic fluorescent substance includes a green fluorescent substance having a maximum light emission wavelength in a 510 nm to 560 nm range when irradiating light including a 450 nm wavelength, and a red fluorescent substance having a maximum light emission wavelength in a 600 nm to 660 nm range when irradiating light including a 450 nm wavelength, the green fluorescent substance and the red fluorescent substance have a molar ratio of 5:1 to 50:1, and the color conversion film has a light emission peak with a full width at half maximum (FWHM) of 50 nm or less in a 510 nm to 560 nm range and a light emission peak with a FWHM of 90 nm or less in a 600 nm to 660 nm range when irradiating light, a method for preparing the same, and a backlight unit including the color conversion film.
