Light-emitting diode display device

A light-emitting diode display device, comprising:

• an array substrate;
• an opposite substrate, disposed opposite to the array substrate;
• a plurality of wall structures, disposed between the array substrate and the opposite substrate, wherein the array substrate, the wall structures and the opposite substrate define at least one accommodating region;
• at least one light-emitting diode, disposed on the array substrate, and located in the at least one accommodating region;
• an upper reflection layer, disposed between the at least one light-emitting diode and the opposite substrate, wherein an orthographic projection of the upper reflection layer on the array substrate at least partially overlapped with an orthographic projection of the at least one light-emitting diode;
• a first light barrier layer, disposed between the upper reflection layer and the opposite substrate;
• a lower reflection layer, disposed on the array substrate, and located in the at least one accommodating region, wherein the orthographic projection of the upper reflection layer on the array substrate is at least partially overlapped with an orthographic projection of the lower reflection layer on the array substrate;
• and
• a light diffusion material layer, filled in the at least one accommodating region.
