    Abstract: Provided is a display device. The display device includes a substrate including a plurality of pixels, an adhesive layer on the substrate, a light emitting diode on the adhesive layer, a planarization layer surrounding the light emitting diode, a connection electrode on the planarization layer, and a transparent protective layer on the connection electrode. At least one layer of the adhesive layer, the planarization layer, and the transparent protective layer includes a plurality of multi-shell structured particles. The multi-shell structured particles are included in the display device so that the adhesion and the adhesion holding power between the light emitting diode and the driving panel are improved to increase the product yield and improve the luminance of the light emitting diode, thereby providing a display device with low power consumption.
