example 1

[0352] To make the anode, Corning15Ω / cm 2 The ITO glass substrate was cut into a size of 50 mm × 50 mm × 0.7 mm, and then the glass substrate was ultrasonically cleaned in isopropanol and pure water for 5 minutes, respectively, and then cleaned by ultraviolet irradiation and ozone exposure for 30 minutes. The resulting glass substrate was loaded into a vacuum deposition apparatus.

[0353] Then, 2T-NATA as a HIL material was vacuum-deposited on the glass substrate to form a thickness of about The HIL. Then, 4,4′-bis[N-(1-naphthyl)-N-phenylamino]biphenyl (NPB) as a hole transport compound was vacuum-deposited on the HIL to form a thickness of about HTL.

[0354] The blue fluorescent host 9,10-di-naphthalen-2-yl-anthracene (ADN) and compound 2 of Synthesis Example 6 as a blue fluorescent dopant were simultaneously deposited on the HTL in a weight ratio of 98:2 to forming a thickness of EML.

[0356] Then, Alq3 is deposited on the EML to form a thickness of...

example 2

[0359] An organic light-emitting device was fabricated in the same manner as in Example 1 except that Compound 11 was used instead of Compound 2 to form an EML.

[0360] The OLED has a 50mA / cm 2 Drive voltage of 6.45V, 2970cd / m at the highest current density 2 High luminosity, luminous efficiency of 5.94cd / A, and 100mA / cm 2 Half-life of 225 hours.

example 3

[0362] An organic light-emitting device was fabricated in the same manner as in Example 1 except that Compound 24 was used instead of Compound 2 to form the EML.

[0363] The OLED has a 50mA / cm 2 Drive voltage of 6.32V, 2310cd / m at the current density 2 High luminosity, luminous efficiency of 4.62cd / A, and 100mA / cm 2 Half-life of 201 hours.

Abstract

The present invention relates to a heterocyclic compound, an organic light-emitting device including the heterocyclic compound, and a flat panel display device including the organic light-emitting device. The heterocyclic compound is represented by the following Formula 1, wherein Ar1, Ar2, X, and R1 to R5 are defined as described in the specification.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2010-0104734 filed with the Korean Intellectual Property Office on October 26, 2010 and Korean Patent Application No. 10-2011-0028213 filed with the Korean Intellectual Property Office on March 29, 2011 Korean Patent Application No., the disclosure of which is hereby incorporated by reference. technical field [0002] The present embodiment relates to a heterocyclic compound represented by Formula 1 and an organic light emitting device including the heterocyclic compound. [0003] Formula 1 [0004] Background technique [0005] The light emitting device is a self-emissive display device, and has a wide viewing angle, high contrast, and short response time. Due to these characteristics, light emitting devices are attracting attention. [0006] Such an organic light emitting device may be roughly classified into an inorganic light emitting device including an emission layer including an inorga...
