Light emitting device
摘要:
A light emitting device having excellent luminance life contains an anode, a cathode, a first organic layer disposed between the anode and the cathode and a second organic layer disposed between the anode and the cathode. The first organic layer contains a compound represented by the formula (C-1), and the second organic layer contains a compound represented by the formula (C-1) and a cross-linked body of a crosslinkable material. Ring R1C and Ring R2C represent an aromatic hydrocarbon ring or an aromatic hetero ring and RC represents an oxygen atom, a sulfur atom or a group represented by the formula (C′-1). Ring R3C and Ring R4C represent an aromatic hydrocarbon ring or an aromatic hetero ring and RC′ represents a carbon atom, a silicon atom, a germanium atom, a tin atom or a lead atom.
