Film-forming composition

摘要

This film-forming composition includes, for example, a polymer, crosslinking agent and light-diffusing agent that contain a triazine ring-containing repeating unit structure such as that represented formula (17), and is able to provide cured films with good light diffusing properties. Furthermore, this film-forming composition, which includes the same polymer, crosslinking agent and fine inorganic particles having a cross-linkable functional group, is able to provide cured films with good high temperature and high humidity resistance.;
