Display panel, mask and method of manufacturing the same

摘要

A display panel includes a substrate, signal lines, a thin film transistor, a pixel electrode and a dummy opening, The substrate has a display area and a peripheral area surrounding the display area. The signal lines are disposed on the substrate and intersect each other to define a unit pixel. The thin film transistor is electrically connected to the signal lines and disposed at the unit pixel. The pixel electrode is electrically connected to the thin film transistor. The pixel electrode is formed in the unit pixel. The dummy opening is disposed at the peripheral area and spaced apart from the signal lines.
