Organic light-emitting diode, method of manufacturing the same, and method of forming material layer

An organic light-emitting device including a first electrode; a second electrode facing the first electrode; an emission layer between the first electrode and the second electrode; a first hole transport layer between the first electrode and the emission layer; and a second hole transport layer between the first hole transport layer and the emission layer, wherein the first hole transport layer includes a first compound represented by Formula 1 and the second hole transport layer includes a second compound represented by Formula 2: 

Organic light-emitting device

There is provided a master glass having a structure capable of preventing damage caused by static electricity. The master glass is a substrate on which a deposition process is experimentally performed by being experimentally loaded loading the master glass into a deposition apparatus before starting the deposition process of the substrate for electronic devices. In one embodiment, a master glass includes first conductive patterns and a second conductive pattern. The first conductive patterns are formed to correspond to a deposition pattern required in a substrate for electronic devices. The second conductive pattern electrically connects all the first conductive patterns to one another.
