Abstract
An array substrate includes a substrate, a plurality of data lines on the substrate, a plurality of scan lines on the substrate, a pixel electrode on the substrate, a shielding common electrode on the substrate, a data test part on the substrate and a shielding common electrode pad on the substrate. The pixel electrode is in a region defined by the data and scan lines adjacent to each other. The shielding common electrode surrounds the pixel electrode. The data test part applies test data voltage to the data lines. A shielding common voltage that has different level from the test data voltage is applied to the shielding common electrode through the shielding common electrode pad.
