Abstract: The present disclosure provides a light-emitting unit and a display device. The light-emitting includes a micro-LED element and a bonding pad. The micro-LED element includes an element pin, the bonding pad includes a bonding pin, in each welding pair of the element pin and the bonding pin, a length of the element pin is greater than a width of the bonding pin, and a non-zero angle is formed between the extending direction of the element pin and the extending direction of the bonding pin. When the element pin is deviated from the bonding pin in a certain range, the element pin can still be aligned accurately with the bonding pin. Thus, a requirement on the alignment precision between the micro-LED element and the bonding pad is lowered in a certain extent, thereby improving the yield.
