Light emitting device

A light emitting device comprising

• 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, wherein
• the first organic layer contains a compound represented by the formula (C-1), and
• the second organic layer is a hole-transporting layer and contains a compound represented by the formula (C-1) and a cross-linked body of a crosslinkable material:
• wherein,
• Ring R1C and Ring R2C each independently represent an aromatic hydrocarbon ring or an aromatic hetero ring, and the foregoing rings optionally have a substituent, and when a plurality of the substituents are present, they may be combined together to form a ring together with atoms to which they are attached,
• RC represents an oxygen atom, a sulfur atom or a group represented by the formula (C′-1),
• wherein,
• Ring R3C and Ring R4C each independently represent an aromatic hydrocarbon ring or an aromatic hetero ring, and the foregoing rings optionally have a substituent, and when a plurality of the substituents are present, they may be combined together to form a ring together with atoms to which they are attached, and
• RC′ represents a carbon atom, a silicon atom, a germanium atom, a tin atom or a lead atom.
