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.

Light-emitting device and displayer

Provided are a LED display unit group and a display panel. The LED display unit group includes a circuit board and pixel units arranged in an array of m rows and n columns on the circuit board. The circuit board includes N metal line layers stacked in sequence and an insulating plate located between adjacent metal line layers. The N metal line layers are electrically connected through a conductive via on the insulating plate, where N&#x2265;2. Each pixel unit includes at least two LED light-emitting chips with different light-emitting colors, where m&#x2265;2, n&#x2265;2. The first metal line layer includes m common A-electrode pads, multiple A-electrode pads and multiple B-electrode pads.
