Abstract
Provided are a display panel and a display device. The display panel includes a substrate and multiple display units located on a side of the substrate. The display units include multiple light-emitting elements. The light-emitting elements include main light-emitting elements and backup light-emitting elements. The number of main light-emitting elements is greater than the number of backup light-emitting elements. The main light-emitting elements are arranged in a first direction. In a second direction, a backup light-emitting element is located between two main light-emitting elements. In the second direction, at least two main light-emitting elements are disposed adjacent to each other. When the display panel is driven to display an image, and when a dead pixel appears in a main light-emitting element, a backup light-emitting element emits light to replace the main light-emitting element in which the dead pixel appears for display.
