Abstract: A liquid drop discharge apparatus is proposed. The liquid drop discharge apparatus includes: an inkjet head discharging ink to each of pixels of a substrate; a laser emitter coupled to the inkjet head, and emitting an aiming laser beam by which a discharged position of a liquid drop from the inkjet head to each of the pixels is aimed; a camera capturing an emitted position of the aiming laser beam on the substrate; and a position alignment unit aligning a position of the inkjet head on the basis of image data obtained from the shooting unit.
