A sealant dispenser comprises: a substrate including a display area; a nozzle forming a sealing pattern by discharging a sealant continuously to surroundings of the display area; and a laser displacement sensor unit light-emitting laser to the substrate, light-receiving the laser reflected from the substrate, and measuring clearance between the nozzle and the substrate, wherein the nozzle maintains regular clearance with the substrate according to the measured value, and an image-forming point defined as a point where the laser is reflected from the substrate is arranged between the neighboring sealing patterns when the neighboring sealing patterns are formed between the neighboring display areas. |
