Abstract
A display panel and a display apparatus are provided. The display panel includes a light-emitting unit, a pixel defining layer, and a light-shielding layer. The light-emitting unit includes first and second electrodes, and a light-emitting layer. The pixel defining layer includes an opening portion where the light-emitting layer is partially located, and a non-opening portion. The first electrode is located in the opening portion in a direction perpendicular to a plane of the substrate and includes first and second openings. In the direction perpendicular to the plane of the substrate, the light-shielding layer does not overlap with the first opening. Orthographic projections of the light-shielding layer and the first electrode on the plane of the substrate are first and second projections, respectively. In a first direction, a difference between a length of the second opening and a sum of lengths of the first and second projections satisfies a preset threshold.
