1. A display panel, the display panel comprising a first display area and a second display area, wherein the display panel comprises:
a base substrate;
a plurality of first repeating units arranged on the base substrate in an array in a row direction and a column direction and located in the first display area, wherein each of the first repeating units comprises at least a first sub-pixel;
a plurality of second repeating units arranged on the base substrate in an array in the row direction and the column direction and located in the second display area, wherein each of the second repeating units comprises at least a second sub-pixel, and a color of light emitted by the first sub-pixel is the same as a color of light emitted by the second sub-pixel; and
a pixel defining layer, wherein the pixel defining layer is disposed on the base substrate and located in both the first display area and the second display area, and the pixel defining layer comprises a first opening located in the first display area and a second opening located in the second display area,
wherein a distribution density of the first repeating units in the first display area is greater than a distribution density of the second repeating units in the second display area;
wherein the first sub-pixel comprises the first opening, the second sub-pixel comprises the second opening, and an area of an orthographic projection of the second opening on the base substrate is greater than an area of an orthographic projection of the first opening on the base substrate;
wherein the pixel defining layer further comprises a third opening in the first display area and a fourth opening in the second display area; each of the first repeating units further comprises a third sub-pixel, each of the second repeating units further comprises a fourth sub-pixel, a color of light emitted by the third sub-pixel is the same as a color of light emitted by the fourth sub-pixel, and the color of the light emitted by the third sub-pixel is different from the color of the light emitted by the first sub-pixel; and the third sub- pixel comprises the third opening, the fourth sub-pixel comprises the fourth opening, and an area of an orthographic projection of the fourth opening on the base substrate is greater than an area of an orthographic projection of the third opening on the base substrate; and
wherein the pixel defining layer further comprises a fifth opening and a seventh opening which are both located in the first display area, and a sixth opening and an eighth opening which are both located in the second display area;
each of the first repeating units further comprises a fifth sub-pixel and a seventh sub-pixel, each of the second repeating units further comprises a sixth sub-pixel and an eighth sub-pixel, colors of light emitted by the fifth sub-pixel, the sixth sub-pixel, the seventh sub-pixel, and the eighth sub-pixel are the same as each other, and the color of the light emitted by the fifth sub-pixel, the color of the light emitted by the first sub-pixel, and the color of the light emitted by the third sub-pixel are different from each other;
and the fifth sub-pixel comprises the fifth opening, the sixth sub-pixel comprises the sixth opening, the seventh sub-pixel comprises the seventh opening, and the eighth sub-pixel comprises the eighth opening, a sum of areas of orthographic projections of the sixth opening and the eighth opening on the base substrate is greater than a sum of areas of orthographic projections of the fifth opening and the seventh opening on the base substrate.
