MICRO LIGHT-EMITTING DIODE CHIP AND DISPLAY PANEL

WIPO Patent Application WO/2021/063035

A1

Provided are a micro light-emitting diode chip and a display panel. The micro light-emitting diode chip comprises a first-type semiconductor layer, a light-emitting layer, a second-type semiconductor layer, a first-type electrode layer, a second-type electrode layer, an insulating passivation layer, and a filler layer. The first-type semiconductor layer comprises a first protrusion and a second protrusion. A recessed region is formed between the first protrusion and the second protrusion. The light-emitting layer and the second-type semiconductor layer are stacked on the second protrusion. The first-type electrode layer covers the first protrusion and a portion of the recessed region. The insulating passivation layer covers a sidewall of the second protrusion, a portion of a surface of the second-type semiconductor layer away from the light-emitting layer and at least a portion of the first-type electrode layer positioned in the recessed region. The second-type electrode layer covers the insulating passivation layer and a portion of the surface of the second-type semiconductor layer away from the light-emitting layer. The filler layer is at least partially filled in the recessed region.
