    摘要： A light-emitting diode chip comprising:
    - a semiconductor body (1) having a plurality of active regions (2), wherein
    - at least one of the active regions (2) has at least two subregions (21...28),
    - the active region (2) has at least one barrier region (3) arranged between two adjacent subregions (21...28) of said at least two subregions (21...28),
    - the at least two subregions (21...28) emit light of mutually different colour during operation of the light-emitting diode chip,
    - in at least one of the subregions (21...28) the emission of light is generated electrically, and
    - the barrier region (3) is configured to hinder a thermally activated redistribution of charge carriers between the two adjacent subregions (21...28), is specified.
