Display panel and display device

A display panel, comprising:

• a metal layer, wherein the metal layer comprises a plurality of metal conductive structures, and the plurality of metal conductive structures are arranged with a period, and are arranged in a first direction with a first period;
• and
• a display function layer, wherein the display function layer comprises a plurality of pixel units, and the plurality of pixel units are arranged with a period, and are arranged in a second direction with a second period,
• wherein the metal layer is located between the display function layer and a display surface of the display panel, and the first period and the second period are in a relationship of an integral multiple,
• wherein one of the plurality of pixel units comprises a first color sub-pixel, and a position {right arrow over (a)}k of the first color sub-pixel is expressed as follows:
• {right arrow over (a)}k=m·{right arrow over (a)}i+n·{right arrow over (a)}j,
• wherein m and n are both integers, a direction of a, intersects a direction of {right arrow over (a)}j, {right arrow over (a)}i is a position of a first color sub-pixel of another one of the plurality of pixel units, and {right arrow over (a)}j is a position of a first color sub-pixel of still another one of the plurality of pixel units, {right arrow over (a)}k, {right arrow over (a)}i, and {right arrow over (a)}j have a same vector starting point, and the vector starting point is a first color sub-pixel of one pixel unit of the plurality of pixel units, the one pixel unit being different from the one of the plurality of pixel units, the another one of the plurality of pixel units and the still another one of the plurality of pixel units.
