Abstract

A light-emitting diode (LED) display panel, a manufacturing method thereof, and an organic light-emitting diode (OLED) display device are disclosed. The LED display panel includes: a base substrate; and a plurality of sub-pixels, a color resistance layer and a light-shielding structure located on the base substrate. The base substrate includes a display region and a periphery region; the sub-pixels are located in the display region; the light-shielding structure is an annular structure located in the periphery region. The light-shielding structure includes a first light-shielding structure and a second light-shielding structure located at a side of the first light-shielding structure away from the base substrate, a second orthographic projection of the second light-shielding structure on the base substrate is located within a first orthographic projection of the first light-shielding structure on the base substrate, and the first orthographic projection is not completely coincident with the second orthographic projection.
