Abstract

A light-emitting diode display panel, a manufacturing method thereof, and an organic light-emitting diode display device are provided. The light-emitting diode display panel includes: a base substrate including a display region and a peripheral region surrounding the display region; a plurality of sub-pixels located in the display region and located at a side of the base substrate; a color-resistance layer located at a side of a second electrode in the sub-pixel away from the base substrate; and a light-blocking structure located in the peripheral region and being an annular structure surrounding the plurality of sub-pixels. The light-blocking structure includes a first light-blocking structure and a second light-blocking structure. The first light-blocking structure includes at least one interval extending in a direction from the display region pointing to the peripheral region. The second light-blocking structure at least fully fills the interval.
