Zusammenfassung:	An apparatus for applying a sealant is provided to suppress the defect of sealant patterns due to interference between a laser and a bracket by forming a space for preventing the interference between the laser and the bracket. A dispenser head(120) has a nozzle(126) for applying a sealant on a substrate. A distance measuring unit measures a distance between the nozzle and the substrate using a light. A first groove(150a) and a second groove(150b) are formed on the dispenser head to prevent interference between the light and the dispenser head. The dispenser head includes a syringe(122) for storing the sealant, and a bracket(124) joined to a lower portion of the syringe. The nozzle is formed on a lower surface of the bracket.
