Abstract
A pixel unit including a pixel electrode, a scan electrode, a common voltage electrode, a data electrode and at least one redundancy electrode is provided. During the fabricating process of the pixel unit, if a particle is simultaneously located between any two of the pixel electrode, the scan electrode and the common voltage electrode, it would cause a short circuit between the two electrodes. The pixel unit can generate a cross-shaped defect signal at the location where a short circuit happens when the pixel unit undergoes an array test or a cell test. The user can thereby quickly locate the defect and repair it.
