Abstract
A display substrate includes multiple light-emitting units. At least one light-emitting unit includes a first light-emitting device that emits first-color light and a second light-emitting device that emits second-color light. The display substrate displays a first color in a first view angle range smaller than a first view angle, and displays a second color in a second view angle range larger than a second view angle. Or, the display substrate displays the second color in the first view angle range smaller than the first view angle, and displays the first color in the second view angle range larger than the second view angle. The view angle is an included angle between a line of sight of a viewer and a normal of a viewing region in the display substrate, and the second view angle is larger than the first view angle.
