ABSTRACT:
A liquid crystal display (LCD) panel with marks for checking cutting precision by visual inspection is provided. A checkerboard mark is formed on an intersection of two adjacent cutting lines of the LCD panel. The checkerboard mark includes a pair of first-square marks in a diagonal relationship and a pair of second-square marks in a diagonal relationship. When completing cutting of the LCD panel, the cutting precision of the LCD panel can be checked by visually inspecting the distance between the square mark and the cutting line or the residue of the checkerboard mark. The checkerboard mark is suitable for various LCD panels' arrangement.
