Abstract
(EN)
The present disclosure relates to an OLED that includes a first electrode; a second electrode facing the first electrode; a first emitting material layer including a first host, a second host and a blue dopant and positioned between the first and second electrodes; a first electron blocking layer including an electron blocking material of a heteroaryl-substituted amine derivative and positioned between the first electrode and the first emitting material layer; and a first hole blocking layer including at least one of a first hole blocking material and a second hole blocking material and positioned between the second electrode and the first emitting material layer, wherein the first host is an anthracene derivative, and the second host is a deuterated anthracene derivative, and wherein the first hole blocking material is a azine derivative, and the second hole blocking material is a benzimidazole derivative.
