The present invention provides various organic electroluminescent elements using a material for a capping layer and a material for a luminous layer, in which the material for a capping layer uses an arylamine material that exhibit excellent stability and durability in the form of a thin film, especially a specific amine compound having a high refractive index and having a high absorbance within a wavelength range from 400 nm to 410 nm in the absorption spectrum at a concentration of 10mol/L; and in which the material for a luminous layer uses a compound containing a heterocyclic compound that has a specific fused ring structure.

Organic electroluminescent element

There is provided an organic electroluminescence device, including at least an anode, a hole transport layer, a light-emitting layer, an electron transport layer, and a cathode in the stated order, the organic electroluminescence device being characterized in that the hole transport layer contains an arylamine compound represented by formula (1), and the light-emitting layer contains a heterocyclic compound having a fused ring structure represented by formula (2) or a heterocyclic compound having a fused ring stricture represented by formula (3), wherein each of formulas (1), (2) and (3) are set forth in the specification.

Organic electroluminescence device

Disclosed is an apparatus for evaluation of a deposition process in organic thin film-manufacturing processes using a chamber employing a deposition-preventing plate, by which it can be predicted whether a thin film layer formed on the deposition-preventing plate will be delaminated. Also provided is a method for evaluating a deposition process of an organic material, using the apparatus.

Apparatus for evaluation of deposition process in manufacturing of organic thin film

Disclosed are an organic light emitting diode and a method of manufacturing the same, the organic light emitting diode including: a light-transmitting substrate including a first region and a second region separated from the first region; a first lower electrode formed on the first region of the light-transmitting substrate and a second lower electrode formed on the second region thereof; a first organic thin film layer including a first emission material layer, formed on the first lower electrode of the first region, and a second organic thin film layer including a second emission material layer, formed on the second lower electrode of the second region; and a light-transmitting upper electrode formed on the first organic thin film layer and the second organic thin film layer and configured such that portions corresponding to the first region and the second region are connected to each other.
