Abstract: A display panel includes a display structure, a touch layer located on a light-exit side of the display substrate, and a black matrix layer located on a side of the layer away from the display substrate. The display substrate includes sub-pixels each having a light-emitting region located within a reference region. The touch layer includes a metal mesh structure including metal lines. Orthogonal projections of the metal lines on the display substrate are located between reference regions where light-emitting regions of the sub-pixels are located. A spacing exists between a metal line adjacent to the light-emitting region of the sub-pixel and the reference region where the light-emitting region is located. The black matrix layer includes openings. An orthogonal projection of each opening on the display substrate surrounds a single light-emitting region and is at least partially located outside a reference region where the single light-emitting region is located.
