Abstract:
1. A method of manufacturing a light emitting element that includes a first electrode and a second electrode interposed by an emission layer and a carrier transfer layer, the carrier transfer layer including a first region formed directly adjacent to the first electrode and a second region formed between the first region and the light emission layer, the method comprising: depositing a liquid material on the first electrode to form a liquid film, the liquid film including a first organic polymer and a second organic polymer that are dissolved in a solvent, and a complex of a semiconductor particle and a light emitting material dispersed in the solvent, a molecular weight of the first organic polymer being greater than that of the second organic polymer; and removing the solvent from the liquid film such that the first organic polymer is formed in the first region, the second organic polymer is formed in the second region and the complex of the semiconductor particle and the light emitting material forms the emission layer directly adjacent to the second electrode, the emission layer including the semiconductor particle and the light emitting material.
