Summary: | To provide a coloring composition for a color conversion optical filter that is used in a display using white light as a light source which enables efficient color conversion into a specific wavelength by absorbing specific backlight, and can improve color reproducibility of a display.SOLUTION: A coloring composition for a color conversion optical filter that is used in a liquid crystal display or an organic EL display contains a perylene compound represented by the following formula (1) and a binder resin. In the formula (1), A represents an aminosulfonyl phenyl group, which may have a substituent; and B represents a phenyl group, which may have a substituent.SELECTED DRAWING: None
【課題】白色光を光源とするディスプレイに用いられる色変換光学フィルター用の着色組成物であって、特定のバックライト光を吸収してある特定の波長に効率よく色変換可能で、かつ、ディスプレイの色再現性をも向上し得る着色組成物を提供する。【解決手段】液晶ディスプレイ又は有機ELディスプレイに用いられる色変換光学フィルター用の着色組成物であって、下記式(1)(式(1)中、Aは置換基を有していてもよいアミノスルホニルフェニル基、Bは置換基を有していてもよいフェニル基を表す。)で表されるペリレン化合物及びバインダー樹脂を含有する着色組成物。【選択図】なし |
