Problems solved by technology

[0007] 2. Using metal as the common electrode, the light at the position of the common electrode is blocked by the metal common electrode, which reduces the aperture ratio of the display unit
Since the insulating layer between the pixel electrode and the common electrode is relatively thick, in order to obtain a larger storage capacitance value, it is often necessary to use a common electrode with a larger width, thereby further reducing the aperture ratio of the display unit
