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.

Abstract: A gate driving circuit includes a plurality of driving stages applying gate signals to a plurality of gate lines of a display panel and a plurality of ripple discharge circuits discharging a ripple voltage of the gate lines. A k-th driving stage (where k is a natural number greater than 1), among the driving stages, outputs a k-th gate signal to a k-th gate line, among the gate lines, in synchronization with a first clock signal, and a k-th ripple discharge circuit, among the ripple discharge circuits, corresponding to the k-th driving stage discharges the ripple voltage of the k-th gate line to a first voltage in synchronization with a second clock signal complementary to the first clock signal.

Abstract: A method of manufacturing a display device including the steps of: forming, on a first mother substrate, pixels including pixel electrodes, gate lines and data lines connected to the pixels; dividing the data lines into groups and connecting the data lines of the same group to one connection line; forming inspection electrodes on the first mother substrate overlapping a shot boundary portion of a mask, the inspection electrodes connected to a plurality of connection lines, respectively; preparing a second mother substrate; forming a common electrode on the second mother substrate; forming a mother panel including the first and second mother substrates and a liquid crystal layer therebetween; applying a first voltage to the common electrode and a second voltage to the inspection electrodes; and determining whether the inspection electrodes and the common electrode are short-circuited based on an image displayed in a display area of the mother panel.
