LIGHT-EMITTING DIODE CHIP, MANUFACTURING METHOD THEREOF AND DISPLAY APPARATUS

A light-emitting diode chip includes: epitaxial structures on one side of substrate, a gap existing between any two adjacent epitaxial structures, first semiconductor patterns of epitaxial structures coupled to form first semiconductor layer; first light-blocking layer on a side of the first semiconductor layer away from substrate, first light-blocking layer having accommodating holes in one-to-one correspondence with epitaxial structures, the light-emitting patterns and the second semiconductor patterns of epitaxial structures being in accommodating holes; second light-blocking layer on a side of first light-blocking layer away from substrate, second light-blocking layer having pixel openings in one-to-one correspondence with accommodating holes; orthographic projections of pixel opening and corresponding accommodating hole on substrate overlap with each other; light processing pattern is in at least one pixel opening; light processing pattern includes color conversion pattern configured to convert light of preset color emitted by light-emitting pattern into light of other color.
