With the manufacturing device of the present disclosure, the rectangle-shaped two-dimensional code can be formed on the non-displaying area of the present disclosure. The width of the rectangle-shaped two-dimensional code is less than that of the present square-shaped two-dimensional code used for representing the same data, thus, the width of the non-displaying area can be reduced without reducing the area of the two-dimensional code to allow the liquid crystal display to have a narrow frame. ## Claims ### Claim 1 A manufacturing device for a liquid crystal panel which has a non-displaying area, comprising: a two-dimensional code generating module configured for generating a rectangle-shaped two-dimensional code according to an amount of data needed to be represented;
