Abstract
A display apparatus includes a gate driver, a data driver, a display panel, a power supply and a common voltage line. The gate driver outputs a gate signal, and the data driver outputs a data signal. The display panel includes a display area displaying images in response to the gate signal and the data signal, and a peripheral area surrounding the display area. The power supply generates a common voltage and supplies the common voltage to the display panel. The common voltage line is disposed in the peripheral area surrounding the display area. and the common voltage line has two ends adjacent to the power supply. One of the two ends, which is disposed farther away from the gate driver, is connected to the power supply to receive the common voltage. Accordingly, the common voltage is differentially applied according to a length of the common voltage line.
