A substrate cutting apparatus and a method of manufacturing a display apparatus by using the substrate cutting apparatus, so that an occurrence of an error in cutting a substrate may be prevented and the substrate may be exactly cut. The substrate cutting apparatus includes an integrated laser beam oscillator where an infrared wavelength laser beam oscillator and a short pulse laser beam oscillator are adjacent to each other and are fixed; a stage on which a substrate is disposed; and a transfer unit that transfers at least one of the substrate and the integrated laser beam oscillator so as to control a short pulse laser beam to be irradiated on a region of the substrate, on which an infrared wavelength laser beam emitted from the integrated laser beam oscillator has just been irradiated.

Substrate cutting apparatus and method of manufacturing display apparatus by using a substrate cutting apparatus

A display panel includes a gate driving circuit, a plurality of gate lines, a plurality of data lines and a dummy gate line. The gate driving circuit is disposed in a peripheral area surrounding a display area. The gate lines are disposed in the display area and receive a plurality of gate signals sequentially outputted from the gate driving circuit. The data lines are disposed in the display area and cross the gate lines. The dummy gate line is disposed adjacent to the last gate line of the gate lines and receives a dummy gate signal transmitted from an external device. Thus, a dummy gate line is adjacent to the last gate line and a pixel electrode connected to the last gate line is affected by a dummy gate signal applied to the dummy gate line.
