Abstract
An organic light-emitting display panel and a manufacturing method thereof and an organic light-emitting display device are provided. The organic light-emitting display panel includes a first light-emitting element, a second light-emitting element, a first color filter layer, a second color filter layer; a color of light emitted by the first light-emitting element is different from a color of light emitted by the second light-emitting element and is same as a color of the first color filter layer, and the color of the light emitted by the second light-emitting element is same as a color of the second color filter layer, a brightness attenuation speed of the light emitted by the first light-emitting element is faster than a brightness attenuation speed of the light emitted by the second light-emitting element; the first color filter layer has a first convex surface; and/or the second color filter layer has a first concave surface.
