Abstract
A LED chip, including: substrate; LEDs on side of the substrate, each including first semiconductor pattern, light emission pattern, second semiconductor pattern sequentially stacked, the first semiconductor patterns of at least two LEDs being formed as single piece to constitute first semiconductor layer; at least one first electrode on side of first semiconductor layer away from the substrate and electrically coupled to first semiconductor layer; second electrodes on side of the second semiconductor patterns away from the substrate, each being electrically coupled to second semiconductor pattern of corresponding LED; pixel defining layer on side of the substrate away from LED, and having pixel openings in one-to-one correspondence with LEDs; and a color conversion pattern within at least two pixel openings, and converting light of first color emitted by the light emission pattern into light of target color other than the first color. The LED chip is Mini-LED or Micro-LED chip.
