    Abstract: An exposure method and an exposure machine according to the present disclosure, which can achieve higher exposure accuracy, belong to the technical field of display. The exposure method comprises the following steps: a mask is placed at a first position above a substrate to be exposed; a first region of a photoresist on the substrate is exposed; the mask is moved to a second position above the substrate; and a second region of the photoresist on the substrate is exposed. As a result, an overlapped region between the first region and the second region of the photoresist is exposed twice. The present disclosure is applicable to the manufacturing of a liquid crystal display device.
