A liquid crystal display comprises: a first substrate; a display area disposed on the first substrate; subpixels disposed in the display area; a scan driver for supplying a scan signal to scan lines connected to the subpixels; a data driver for supplying a data signal to data lines connected to the subpixels; first transistors disposed on the first substrate adjacent to one side of the display area and connected to the data lines; second transistors disposed on the first substrate adjacent to the other side of the display area and connected to the scan lines; and a test pad connected to the first transistors and second transistors.
