Light-emitting device and manufacturing method thereof |
摘要 |
A light emitting element having a superior light emitting characteristic is provided by forming a region partly including a phosphor (light emitting region) in manufacturing of a light emitting element having an organic compound layer using a high molecular weight material. A solution in which a high polymer having a degree of polymerization of 50 or more is dissolved in a solvent is applied by a spin coating method, and then a low polymer which is composed of the same repetition units as the high polymer and has a degree of polymerization of 2 to 5 and a phosphor are coevaporated to form a light emitting region ( 105 ) and only a low polymer is vapor-deposited on the light emitting region to form an organic compound layer ( 103 ). Thus, the light emitting region ( 105 ) can be partly formed.
