Display panel and display apparatus

A display apparatus, comprising:

• a display panel;
• and
• an optical function element,
• wherein the display panel has a conventional display region and a function display region where the optical function element is provided;
• the display panel comprises first pixel circuits located in the conventional display region, first fixed potential lines located in the conventional display region, second pixel circuits located in the function display region, and second fixed potential lines located in the function display region, wherein each of the first fixed potential lines extends along a first direction, and the first fixed potential lines are arranged along a second direction and electrically connected to the first pixel circuits;
• each of the second fixed potential lines extends along a third direction, and the second fixed potential lines are arranged along a fourth direction and are electrically connected to the second pixel circuits;
• and
• wherein a distance between two adjacent first fixed potential lines of the first fixed potential lines is greater than a distance between two adjacent second fixed potential lines of the second fixed potential lines.
