1. A display panel, comprising:
a display region and a non-display region at least partially surrounding the display region;
a first base plate and a second base plate opposite to each other; and
first reflection structures and first pixel electrodes in the non-display region and second pixel electrodes in the display region;
wherein:
the first base plate includes a first substrate;
the second base plate includes a light-blocking layer;
the light-blocking layer includes at least one first opening in the non-display region and includes second openings in the display region;
along a first direction, the at least one first opening and the second openings penetrate through the light-blocking layer;
the first direction is a thickness direction of the display panel;
along the first direction, a projection of a first reflection structure overlaps a projection of a corresponding first opening of the at least one first opening;
along the first direction, the second pixel electrodes overlap the second openings;
along the first direction, an overlapping area of one first pixel electrode of the first pixel electrodes and a corresponding first opening of the at least one first opening is S01;
along the first direction, a projection of the corresponding first opening on the first substrate has a total area S0;
along the first direction, an overlapping area of one second pixel electrode of the second pixel electrodes and a corresponding second opening of the second openings is S02; and
along the first direction, a projection of the corresponding second opening on the first substrate has a total area S00, wherein S01/S0>S02/S00.
