Title:
COLOR CONVERSION COMPOSITION, COLOR CONVERSION FILM AND BACKLIGHT UNIT, DISPLAY AND LIGHTING DEVICE EACH COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2017/014068
Kind Code:
A1
Abstract:
A color conversion composition which converts incident light to light having a longer wavelength than the incident light, and which contains the following components (A)-(C):
(A) at least one luminescent material;
(B) a binder resin; and
(C) at least one substance selected from among tertiary amines, catechol derivatives and nickel compounds.
With respect to this color conversion composition, the tertiary amines, the catechol derivatives and the nickel compounds have a molar extinction coefficient ε of 100 or less over the whole wavelength range from 400 nm to 800 nm (inclusive). This color conversion composition achieves a good balance between improvement of color reproducibility and durability if used for a liquid crystal display or an LED lighting device.
