Abstract: The disclosure provides a light-emitting device and a displayer. Herein, the light-emitting device includes a substrate, a light-emitting chip, a first light-transmitting layer, a second light-transmitting layer and a nano coating. The light transmittance of the second light-transmitting layer is greater than the light transmittance of the first light-transmitting layer. A reference surface corresponding to the light-emitting chip is arranged above the substrate, and the reference surface is higher than the bottom surface of the light-emitting chip and not higher than the top surface of the light-emitting chip. The first light-transmitting layer covers the surface of the light-emitting chip below the reference surface, and the second light-transmitting layer covers the surface of the light-emitting chip above the reference surface. The nano coating covers the outer surface of the first light-transmitting layer, the outer surface of the second light-transmitting layer and the side surface of the substrate.
