Example Embodiment
[0094] Example 1
[0095] The vacuum degree is 1×10 -5 A thin film of Pa was deposited on a glass substrate containing indium tin oxide (ITO) (film thickness of 100 nm) as the anode by a vacuum evaporation method.
[0096] The compound HAT-CN was vapor-deposited on the substrate to form a hole injection layer (HIL) with a film thickness of 60 nm.
[0097] The compound NPB was deposited on the hole injection layer (HIL) to form a hole transport layer (HTL) with a thickness of 20 nm.
[0098] Compound 1 and Compound 2 were co-evaporated on the hole transport layer (HTL) to form a light-emitting layer (EML) with a thickness of 35 nm. The concentration of compound 2 in the light-emitting layer (EML) was 97%, and the concentration of compound B was 3%.
[0099] Compound A-2 and LiQ were co-evaporated on the light-emitting layer (EML), and the two materials were vaporized at the same rate to form an electron transport layer (ETL) with a thickness of 35 nm.
[0100] LiF was vapor-deposited on ...
Example Embodiment
[0104] Example 2-3
[0105] Using the compound in Table 1 instead of Compound A-2, an organic electronic light-emitting device was fabricated in the same manner as in Example 1.
