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.

An apparatus for driving a display device includes a plurality of stage connected to each other, wherein each stage includes first to seventh transistors and first and second capacitors, the seventh transistor is connected to one terminal of the first capacitor, and a ratio of an area of the first capacitor to a channel width of the seventh transistor is less than 40. Accordingly, since the ratio of the area of the capacitor to the channel width of the transistor is less than 40, deterioration may be remarkably reduced in a low temperature test.
