Pixel structure and display panel

A display panel, comprising:

• a first substrate;
• a scan line disposed on the first substrate;
• a data line disposed on the first substrate;
• an active component electrically connected to the scan line and the data line;
• a pixel electrode disposed on the first substrate and electrically connected to the active component;
• a first dielectric layer disposed on the first substrate and at least covering the pixel electrode;
• a common electrode at least partially disposed on the first dielectric layer, wherein the common electrode has at least two first branched electrodes and a first opening between the first branched electrodes, and the first branched electrodes and the first opening on the first substrate at least partially overlap with the pixel electrode in the projection direction;
• at least one protrusion disposed on the first dielectric layer, wherein the protrusion is at least partially disposed in the first opening between the first branched electrodes, and the pixel electrode and the protrusion are respectively disposed on two sides of the first dielectric layer;
• a second substrate opposite to the first substrate;
• and
• a display medium layer disposed between the first substrate and the second substrate.
