The invention discloses an exposure procedure of liquid crystal panels, and the exposure procedure is used in an exposure machine for manufacturing a plurality of liquid crystal panels. The exposure procedure comprises the following steps: carrying out exposure on a glass substrate for manufacturing the plurality of liquid crystal panels by a first mask with a plurality of aligned marks corresponding to a plurality of subsequent masks, and forming the plurality of aligned marks corresponding to the plurality of subsequent masks on the glass substrate; and according to the sequence of the plurality of subsequent masks, respectively utilizing the plurality of aligned marks to carry out the aligning procedure and the exposure procedure on the plurality of aligned marks corresponding to the subsequent masks on the subsequent masks and the glass substrate so as to form patterns, wherein corresponding to the same liquid crystal panel area, the plurality of aligned marks needed by all the subsequent marks have different coordinate positions respectively on the glass substrate.
