Claim 14:
15. The light emitting device according to claim 1, wherein said first organic layer is a layer further comprising a compound represented by the following formula (H-1), a polymer compound comprising at least one selected from the group consisting of a non-crosslinkable constitutional unit represented by the following formula (Y) and a non-crosslinkable constitutional unit represented by the following formula (Z), or both the compounds:, , wherein,
ArH1 and ArH2 each independently represent an aryl group or a monovalent heterocyclic group, and the foregoing groups optionally have a substituent,
nH1 and nH2 each independently represent 0 or 1, and when a plurality of nH1 are present, they may be the same or different, and the plurality of nH2 may be the same or different,
nH3 represents an integer of 0 or more and 10 or less,
LH1 represents an arylene group, a divalent heterocyclic group, or a group represented by —[C(RH11)2]nH11-, and the foregoing groups optionally have a substituent, and when a plurality of LH1 are present, they may be the same or different, and nH11 represents an integer of 1 or more and 10 or less,
RH11 represents a hydrogen atom, an alkyl group, a cycloalkyl group, an alkoxy group, a cycloalkoxy group, an aryl group or a monovalent heterocyclic group, and the foregoing groups optionally have a substituent,
a plurality of RH11 may be the same or different and may be combined together to form a ring together with carbon atoms to which they are attached,
LH2 represents a group represented by —N(-LH21-RH21)—, and when a plurality of LH2 are present, they may be the same or different, LH21 represents a single bond, an arylene group or a divalent heterocyclic group, and the foregoing groups optionally have a substituent, and RH21 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,

ArY1  (Y), wherein, ArY1 represents an arylene group which optionally has a substituent,
