Abstract
A display panel and a display module are provided. The display panel includes a substrate and a light-emitting device layer located on the substrate. The light-emitting device layer includes a plurality of effective light-emitting regions and a non-light-emitting region. The display panel further includes a first light absorbing layer, and the first light absorbing layer is disposed on a side of the light-emitting device layer facing a light-emitting side of the display panel, and is disposed corresponding to the non-light-emitting region. The first light absorbing layer is configured for absorbing an ambient light reflected by a metal electrode in the non-light-emitting region to replace a polarizer.
