Abstract: A laser processing apparatus may include: a laser generator configured to generate a laser beam; a stage configured to support a target object; at least one supply nozzle on the stage to eject an air toward the stage; a suction unit configured to inhale external air; and a suction structure on the stage and adjacent to the at least one supply nozzle. The suction structure may include a suction hole connected to the suction unit to inhale the external air. The suction structure may include an inclined surface in which the suction hole is defined. The suction structure may include a first surface adjacent to the supply nozzle, and an opening may be defined in a region of the first surface adjacent to a bottom surface. A distance between the inclined surface and the target object may be less than or equal to a height of the opening.

Abstract: A magnet plate for manufacturing a display device is disclosed. In one aspect, the plate includes at least two magnet units formed in a first direction, each magnet unit including first and second linear motion (LM) guides. The plate also includes a support plate attached to the LM guides. The magnet unit also includes a magnet supporter comprising an upper portion including a magnet coupling part, a lower portion including a plurality of cam followers, and at least two first transfer plate coupling protrusions formed at a predetermined interval. The magnet unit further includes a magnet guide plate placed beneath the magnet supporter and including a guide cam hole into which the cam follower is inserted. The guide cam hole is oblique with respect to the first direction and has a predetermined width such that the cam follower moves within the guide cam hole.
