A method of manufacturing a display panel including a step of segmenting a large sized substrate into an individual substrate along alignment marks formed in the large sized substrate comprising:
- forming a slant mark formed by a plurality of pairs of scale lines that are symmetric to each other with respect to a center line, the center line being coincident with a center line between the alignment marks;
- and
- segmenting the slant mark at the same time when the large sized substrate is segmented into the individual substrate along the alignment marks to form remaining portions of the alignment marks and a remaining portion of the slant mark in the individual substrate.
