Abstract
Description
更に近年、表示素子の色純度や色分離を十分にし、画像画質を高いものにするために、特に380~500nmの波長を選択的に吸収する光吸収剤が求められている。これらの光吸収剤には、光吸収が特別に急峻であること、即ちλmaxの半値幅が小さいこと、また光や熱等により機能が失われないことが求められている。
カラーフィルタに用いられる光吸収剤には、耐熱性の高さにより有機及び/又は無機顔料が用いられてきたが、顔料であるため表示装置としての輝度を低下させてしまうという問題があり、光源の輝度を高めることでこの問題を解決してきた。しかし、低消費電力化の流れに伴い、溶剤や樹脂組成物に対する溶解性が優れ、耐熱性の高い染料の開発、該染料を用いたカラーフィルタの開発が盛んになっている。特許文献1~3には、特定の構造を有する化合物を用いた染料が開示されている。特許文献4には、特定の構造を有する化合物を用いた光学フィルタが開示されている。
