ABSTRACT:
A light emitting device is provided which has a structure for lowering energy barriers at interfaces between layers of a laminate organic compound layer. A mixed layer (105) composed of a material that constitutes an organic compound layer (1) (102) and a material that constitutes an organic compound layer (2) (103) is formed at the interface between the organic compound layer (1) (102) and the organic compound layer (2) (103). The energy barrier formed between the organic compound layer (1) (102) and the organic compound layer (2) (103) thus can be lowered.
