Display substrate and method of manufacturing a motherboard for the same

摘要

A display substrate includes a signal line, a test switch, a test pad, and a first electrostatic dispersion line. The signal line is formed in the display area of a base substrate. The test switch is formed in a peripheral area of the base substrate surrounding the display area. The test switch applies a test signal to the signal line. The test pad is electrically connected to the test switch and receives the test signal. The first electrostatic dispersion line is extended from the test pad to an end of the base substrate.

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.
