Electroluminescent device, manufacturing method thereof, and display device comprising the same

A method of forming an electroluminescent device, the method comprising

• disposing a first electrode and a second electrode facing each other;
• disposing an emission layer between the first electrode and the second electrode, the emission layer comprising light emitting particles;
• disposing an electron transport layer between the first electrode and the emission layer, the electron transport layer comprising
• inorganic oxide particles, and
• a metal-organic compound or a thermal decomposition product of the metal-organic compound;
• and
• disposing a hole transport layer between the second electrode and the emission layer,
• wherein the metal-organic compound comprises an oleate compound.
