Method of aligning and laminating for panels and alignment mark

A method of aligning and laminating for panels, comprising:

• forming four alignment marks on each of a plurality of the panels via a photomask, wherein the panels comprise a first panel, a second panel and a third panel, the four alignment marks are located on four corners of each of the panels, respectively, the four alignment marks are a first corner mark, a second corner mark, a third corner mark and a shifting mark, the first corner mark and the second corner mark are symmetrical, the second corner mark and the third corner mark are symmetrical, and the shifting mark is asymmetric to all of the first corner mark, the second corner mark and the third corner mark;
• aligning and laminating the first panel and the second panel to form a double layer panel, wherein the second panel is rotated 180 degrees relatively to the first panel, the first corner mark of the first panel is aligned to the third corner mark of the second panel, the third corner mark of the first panel is aligned to the first corner mark of the second panel, and the double layer panel is formed after laminating;
• and
• aligning and laminating the double layer panel and the third panel to form a triple layer panel, wherein the second corner mark of the first panel is aligned to the second corner mark of the third panel, the shifting mark of the first panel is aligned to the shifting mark of the third panel, and the triple layer panel is formed after laminating.
