1. A display device comprising:

  • a multiplicity of pixels;

    a connection carrier comprising a multiplicity of switches;

    a multiplicity of inorganic light-emitting diode chips, each pixel containing at least one of the light-emitting diode chips;

    a contact layer electrically conductively connecting at least two light-emitting diode chips to one another; and

    an optical body disposed downstream of and proximate to at least a portion of the light-emitting diode chips, wherein each light-emitting diode chip is mechanically fixed and electrically connected to the connection carrier, wherein each switch is designed to drive at least one light-emitting diode chip or each switch is assigned one-to-one to a light-emitting diode chip, wherein the light-emitting diode chips are imaging elements of the display device, wherein electromagnetic radiation generated by the light-emitting diode chips during operation at least partly passes through the optical body, wherein the electromagnetic radiation is optically expanded upon passing through the optical body, and wherein the contact layer at least in places directly adjoins the light-emitting diode chips and the optical body, the contact layer electrically conductively connecting the light-emitting diode chips to one another.
