Abstract
An LCD with a uniform common voltage and a method thereof. The present invention method includes providing a lower substrate, forming scan lines and data lines, then forming common electrodes and common electrode pads electrically connecting the common electrodes. The method also includes providing an upper substrate, forming photo spacers corresponding to each of the electrode pad, then forming a conductive material layer covering each photo spacer, combining the two substrates and connecting the conductive material layer on the photo spacers to the common electrode pads, and sealing the two substrates.
