1. A bottom-emission light-emitting diode (LED) display, comprising:
a transparent substrate;
a plurality of LEDs bonded on the substrate;
a packaging layer formed on the substrate to cover the LEDs;
a reflecting layer formed on the packaging layer to reflect light emitted by the plurality of LEDs; and
nanoparticles disposed between the packaging layer and the reflecting layer, thereby resulting the reflecting layer with an irregular shape;
wherein the reflecting layer has a non-smooth shape.
