Abstract: A deposition source evaporating apparatus includes a crucible set for accommodating a deposition source, a spray unit positioned on the crucible set, a heater positioned in the crucible set for heating the crucible set to evaporate the deposition source through the spray unit, and a heat radiation preventing plate surrounding the spray unit for blocking radiation of heat at a side of the spray unit. At least one of the crucible unit and the heat radiation preventing plate includes a carbon fiber composite material.

Abstract: A linear evaporation source includes: a crucible accommodating an evaporation material; a heating unit enclosing the crucible and heating the crucible; and a nozzle unit above the crucible, the nozzle unit including a nozzle plate and at least one nozzle protruding from the nozzle plate. A length of the crucible is about 5 times to about 30 times greater than a width of the crucible. The crucible includes molybdenum (Mo) in an amount of about 95.0 percentage by weight (wt %) to about 99.99 wt % and lanthanum oxide (La2O3) in an amount of about 0.01 wt % to about 5 wt %, with respect to the total weight of the crucible.
