Abstract
In accordance with one or more embodiments of the present disclosure, a method of manufacturing a light-emitting element includes forming an anode on a substrate, forming a first transport layer including one or more first polar compounds on the anode, forming a first non-polar solvent layer on the first transport layer, forming a first polar solution layer including one or more light-emitting compounds on the first non-polar solution layer, drying a polar solvent of the first polar solution layer and the first non-polar solvent layer so that a light-emitting layer including the one or more light-emitting compounds is formed on the first transport layer and forming a cathode on the light-emitting layer. The cathode is disposed opposite to the anode. As such, damage to the first transport layer may be reduced when forming the light-emitting layer, which may improve the reliability and productivity of a manufacturing process.
