Abstract
The present application relates to a light emitting diode, a light emitting device, and a display device. The light emitting device includes a light emitting diode and a substrate; the substrate is coated with a bonding substance; the light emitting diode is provided with a positive electrode pad and a negative electrode pad; the surface of the positive electrode pad and/or the negative electrode pad is provided with a plurality of protrusions which are embedded in the bonding substance; and the positive electrode pads and the negative electrode pads are fixed to the substrate through the bonding substance. The embodiment of the present application provides projections on the pad of the light emitting diode, avoids the need of increasing the area of the pad, increases the contact area between the pad and the solder with the constant pad area, improves the bonding stability between the light emitting diode and the substrate, and reduces the production cost.
