Display panel and display device

A display device, comprising;

• a display panel,
• wherein the display panel comprises:
• a display region, wherein the display region comprises a first display region and a second display region;
• wherein the display panel comprises:
• a substrate;
• and
• a plurality of organic light-emitting units, which is located in the display region on a first side of the substrate;
• wherein the plurality of organic light-emitting units is arranged in at least of following manners:
• an area of at least one of the plurality of organic light-emitting units in the second display region is smaller than an area of each of the plurality of organic light-emitting units with a same light-emitting color in the first display region, or density of the plurality of organic light-emitting units in the first display region is greater than a density of the plurality of organic light-emitting units in the second display region;
• and
• wherein the second display region comprises at least one quantum dot light-emitting unit, and the at least one quantum dot light-emitting unit does not overlap the plurality of organic light-emitting units in a direction perpendicular to a plane where the display panel is located;
• and each of the at least one quantum dot light-emitting unit emits light of a same color as at least one of the plurality of organic light-emitting units located in the second display region.
