Abstract

A display element includes: multiple light-emitting elements, at least one light-emitting element includes an anode layer and a cathode layer arranged opposite to each other, and at least two light-emitting units located between the anode layer and the cathode layer. When an application environment of the display element changes from a normal temperature to a first temperature, a change amount of a horizontal coordinate of a white point of the display element is less than or equal to 0.002, a change amount of a vertical coordinate of the white point of the display element is less than or equal to 0.008, and a color shift value of the display element is less than or equal to 1.4.
