Abstract
A liquid crystal cell panel includes a first substrate from which is formed a thin film transistor array substrate, the first substrate including a plurality of unit cells and test terminals which respectively correspond to the unit cells, and a second substrate which faces the first substrate and from which is formed a color filter substrate. The first substrate further includes a first cutting pattern at each of a plurality of corners thereof, and the second substrate includes a second cutting pattern at each of a plurality of corners thereof, the second cutting patterns corresponding one-to-one with the first cutting patterns. Corresponding first and second cutting patterns cross each other in a plan view, and the crossing first and second cutting patterns expose a test terminal adjacent to the crossing first and second cutting patterns to outside the liquid crystal cell panel.
