A light-emitting diode and a light-emitting device are provided. The light-emitting diode defines that a distance between geometric centers of adjacent platform regions in the current spreading layer is equal, that is, a circle is drawn with a geometric center of any platform region as a center and the distance between the geometric centers of adjacent platform regions as a radius, and centers of adjacent platform regions are located on the circle. Thus, the adjacent platform regions form a complementary pattern when current spreads. Taking one platform region as an example, an overlapping area of the current spread between any adjacent platform regions is equal, thereby achieving an effect of uniform current diffusion. In addition, formation of the recessed regions correspondingly reduce a content of the current spreading layer (such as GaP), thereby reducing the light absorption of the current spreading layer and increasing the light-emitting rate of the chip.

Provided are a display panel and a display device. In the display panel, a first metal layer has slots provided with electrode connection lines. The electrode connection lines respectively have a first end connected to a sub-pixel and a second end connected to a pixel circuit. The electrode connection lines in a connection-line group include a first connection line and a second connection line, which are located in different slots.
