It is an object to provide a composition in which an anthracene derivative is dissolved and a technique in which a thin film that has a favorable film quality is formed by a wet process using the composition. In addition, it is another object to manufacture a highly reliable light-emitting element using the composition at low cost with high productivity. A composition having a solvent and an anthracene derivative having one anthracene structure and one carbazolyl group which is bonded to the anthracene structure directly or through a phenyl group is formed. A thin film with a favorable film quality can be formed by a wet process using the composition. Accordingly, a highly reliable light-emitting element can be manufactured using such a thin film.
本发明的目的是提供一种含有
蒽衍
生物溶解的组合物和一种利用该组合物通过湿法工艺形成具有良好薄膜质量的薄膜的技术。此外,另一个目的是使用该组合物以低成本和高生产率制造高可靠性的发光元件。所述组合物包含溶剂和具有一个
蒽结构和一个
咔唑基固定于
蒽结构上,直接或通过苯基结构连接的
蒽衍
生物。使用该组合物可以通过湿法工艺形成具有良好薄膜质量的薄膜。因此,可以使用这样的薄膜制造高可靠性的发光元件。
