Abstract: An apparatus and a method for forming a seal pattern of a flat panel display device are provided to form an uniform seal pattern without short circuit by selectively driving first and second gap sensors along a movement direction of a head block to detect a gap between a substrate and a discharge nozzle. A substrate is received on a stage. A plurality of unit display panels having an active area is formed in the substrate. A head block(200) has at least one syringe(400). A discharge nozzle(410) for forming a seal pattern at each display panel of the substrate received on the stage is mounted on the syringe. A moving unit moves the head block. A plurality of gap sensors(500) is mounted on the head block and is selectively driven along a movement direction of the head block to detect a gap between the substrate and the discharge nozzle.
