Claim 9:
10. The light emitting device according to claim 6, wherein said constitutional unit having a crosslinkable group is at least one selected from the group consisting of a constitutional unit represented by the following formula (2) and a constitutional unit represented by the following formula (2′):, , wherein,
nA represents an integer of 0 or more and 5 or less, and n represents an integer of 1 or more and 5 or less, and when a plurality of nA are present, they may be the same or different,
Ar3 represents an aromatic hydrocarbon group or a heterocyclic group, and the foregoing groups optionally have a substituent,
LA represents an alkylene group, a cycloalkylene group, an arylene group, a divalent heterocyclic group, a group represented by —NR′—, an oxygen atom or a sulfur atom, and the foregoing groups optionally have a substituent, R′ represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group or a monovalent heterocyclic group, and the foregoing groups optionally have a substituent, and when a plurality of LA are present, they may be the same or different,
X represents said crosslinkable group, and when a plurality of X are present, they may be the same or different,, , wherein,
mA represents an integer of 0 or more and 5 or less, m represents an integer of 1 or more and 5 or less, and c represents 0 or 1, and when a plurality of mA are present, they may be the same or different,
Ar5 represents an aromatic hydrocarbon group, a heterocyclic group, or a group in which at least one aromatic hydrocarbon group and at least one heterocyclic group are bonded directly, and the foregoing groups optionally have a substituent,
Ar4 and Ar6 each independently represent an arylene group or a divalent heterocyclic group, and the foregoing groups optionally have a substituent,
Ar4, Ar5 and Ar6 each may be bonded directly or via an oxygen atom or a sulfur atom, to a group other than that group bonding to a nitrogen atom to which that group is bonded, to form a ring,
KA represents an alkylene group, a cycloalkylene group, an arylene group, a divalent heterocyclic group, a group represented by —NR″—, an oxygen atom or a sulfur atom, and the foregoing groups optionally have a substituent, R″ represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group or a monovalent heterocyclic group, and the foregoing groups optionally have a substituent, and when a plurality of KA are present, they may be the same or different,
X′ represents said crosslinkable group, a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group or a monovalent heterocyclic group, and the foregoing groups optionally have a substituent, and when a plurality of X′ are present, they may be the same or different, however, at least one X′ is said crosslinkable group.
