Display panel and display apparatus

A display apparatus, comprising a display panel, wherein the display panel comprises:

• a display area comprising a light-transmitting display area and a normal display area surrounding the light-transmitting display area, wherein the light-transmitting display area comprises a light-sensing element area and at least one transition area surrounding the light-sensing element area;
• a substrate located on one side of the display area;
• a light shield layer located on a side of the display area away from the substrate, wherein the light shield layer comprises a plurality of light shield portions arranged at intervals, and an opening area is provided between any two adjacent light shield portions, and wherein first orthographic projections of a plurality of the opening areas are located on the substrate in the light-sensing element area, second orthographic projections of the plurality of opening areas are located the substrate in the transition area, third orthographic projections of the plurality of opening areas are located on the substrate in the normal display area, a ratio of a sum of areas of the first orthographic projections to an area of the light-sensing element area is a first opening ratio, a ratio of a sum of areas of the second orthographic projections to an area of the transition area is a second opening ratio, a ratio of a sum of areas of the third orthographic projections to an area of the normal display area is a third opening ratio, and a size of the second opening ratio is between a size of the first opening ratio and a size of the third opening ratio.
