<p>Provided are project is to provide a light emitting element capable of creating a long life span by suppressing or preventing a change in a light emitting color while having excellent light emitting efficiency when the element is formed by using a liquid phase process, a light emitting device including the same, and a display device, and an electronic device. A light emitting element (1) includes a light emitting layer (7) formed between an anode (3) and a cathode (10), a first light emitting sub layer (6) including a first light emitting sub material having the same or similar characteristics as/to a host material of the light emitting layer (7) and formed between the anode (3) and the light emitting layer (7) while touching the light emitting layer (7), and a second light emitting layer (8) including a second light emitting sub material having the same or similar characteristics as/to the host material of the light emitting layer (7) and formed between the cathode (10) and the light emitting layer (7) while touching the light emitting layer (7). The light emitting layer (7) and the first light emitting sub layer (6) individually include a polymer material. [Reference numerals] (8) Application layer or a deposition layer; (9) Deposition layer; (AA) Application layer</p> |
