<P>PROBLEM TO BE SOLVED: To provide a composition, in which light is emitted from a light-emitting element at high light-emitting efficiency when being used for the production of the light-emitting element. <P>SOLUTION: The composition includes: a polymer including a repeating unit expressed by a formula (1) (wherein, Ar denotes an aryl group which may have a substituent or a monovalent heterocyclic group which may have a substituent; R<SP POS="POST">1</SP>denotes a substituent; m denotes the integer of 0 to 3. Ar and m, a plurality of which exist, may be the same as or different from each other. When a plurality of R<SP POS="POST">1</SP>s exist, they may be the same as or different from each other); and a compound exhibiting phosphorescence emission. <P>COPYRIGHT: (C)2012,JPO&INPIT |
