PURPOSE: A deposition source for depositing electro-luminescent layer having heat insulation layer is provided to maintain constant temperature and to prevent accumulation of organic vapor around an aperture by transferring heat from a heater to a vapor efflux aperture. CONSTITUTION: A deposition source includes a bottom member, a sidewall member, an upper member, and a cover. The sidewall member(101b) is positioned at an edge portion of the bottom member and includes a heater(110). The heater transfers heat to a deposition material. The upper member(101d) includes a vapor efflux aperture(101a,330a). The cover is positioned adjacent to the upper member while being fixed on the sidewall member. The cover includes an aperture(320a) at a position corresponding to the vapor efflux aperture.
