Abstract: A pyrene-based compound, an organic light-emitting diode including the compound and an organic light-emitting apparatus including the compound are disclosed.

Abstract: A low temperature deposition device according to the present invention includes: a thermal deposition source unit spraying a deposition beam; a differential pumping unit connected to the thermal deposition source unit and passing the deposition beam; and a cooling gas inlet connected to the differential pumping unit and inserting a cooling gas inside the differential pumping unit to cool the deposition beam. According to the present invention, the inorganic deposition beam of low temperature is deposited on the substrate to form the inorganic metal layer of low temperature so that the damage to the organic layer maybe minimized when forming the inorganic metal layer of low temperature on the organic layer.
