Title:
LIGHT-EMITTING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/198975
Kind Code:
A1
Abstract:
Provided is a light-emitting element having excellent luminance life. Disclosed is a light-emitting element comprising a positive electrode, a negative electrode, a first organic layer provided between the positive electrode and the negative electrode, and a second organic layer provided between the positive electrode and the negative electrode, wherein the first organic layer is a layer including a compound represented by formula (C-1), and the second organic layer is a layer including a compound represented by formula (C-1) and a crosslinked product of a crosslinking material. (In the formula, ring R1C and ring R2C represent an aromatic hydrocarbon ring or an aromatic heterocycle. RC represents an oxygen atom, a sulfur atom, or a group represented by formula (C'-1).) (In the formula, ring R3C and ring R4C represent an aromatic hydrocarbon ring or an aromatic heterocycle. RC' represents a carbon atom, a silicon atom, a germanium atom, a tin atom, or a lead atom.)
