a deposition apparatus may uniformly control deposited quantities of a plurality of depositing sources by efficiently determining an abnormal depositing source . the deposition apparatus may reduce loss of materials by exactly determining an abnormal depositing source . the deposition apparatus includes : a plurality of depositing sources spraying a deposition material ; a substrate holder fixing a substrate to face the depositing source ; a depositing source shutter disposed at one side of the depositing source and opening and closing an passage of each depositing source ; and a main shutter disposed between the depositing source and the substrate fixed to the substrate holder and depositing a part of the deposition material on the substrate through the main shutter .
