Display apparatus and method of manufacturing the same

Abstract

A display apparatus includes a substrate, a first electrode on the substrate, a second electrode on the first electrode, an emission layer between the first electrode and the second electrode, and a hole transport layer located between the first electrode and the emission layer, and including a first mixed layer in which a first material and a second material different from the first material are mixed with each other, wherein an absolute value of a difference between a Highest Occupied Molecular Orbital (HOMO) energy level of the first material and a HOMO energy level of the second material is about 0.3 eV or less.
