Abstract
A present application provides a light-emitting device and a method of manufacturing the same. The light-emitting device includes an anode, a hole transport layer, a light-emitting layer, an electron transport layer, and a cathode all laminated together. The hole transport layer is treated with a high boiling point polar solution to reduce a Coulomb force of the hole transport layer. The light-emitting device of the present application can improve light-emitting efficiency of the light-emitting device.
