| 摘要 |
The organic EL light emitting device of the invention has an organic EL light emitting layer ( 3 a, 3 b, 3 c) and an electrode ( 1, 4 ) for applying a voltage to the organic EL light emitting layer. The organic EL light emitting layer includes a hyperbranched polymer layer having hyperbranched macromolecules uniaxially aligned with a degree of alignment of 0.95 or more, and emits light with a high emission polarization ratio.
