Abstract:
1. A display substrate comprising: a signal line formed in a display area of a base substrate; a test switch formed in a peripheral area of the base substrate, wherein the peripheral area surrounds the display area, and the test switch applies a test signal to the signal line; a test pad electrically connected to the test switch, wherein the test pad receives the test signal; a first electrostatic dispersion line extended from the test pad to an edge of the base substrate; a test signal line connected to the test switch to apply the test signal to the test switch, wherein the test signal line is extended from the test pad; an organic layer formed in the display area and the peripheral area to cover the signal line and the test switch; and a common voltage line formed on the organic layer and formed in the peripheral area of the base substrate, wherein the common voltage line transmits a common voltage signal to the display area, and wherein the test pad is directly connected to the test switch by the test signal line.
