Abstract
Disclosed is a composition including an anthracene derivative and a solvent and a method for fabricating a light-emitting element using the composition. The anthracene derivative has a diphenylanthracene moiety and a carbazole moiety linked to one of the phenyl groups of the diphenylanthracene moiety. The use of the composition enables the formation of a light-emitting element by a wet type method such as an ink-jet method, a spin coating method, and a dip coating method.
