Optical Assembly and Display Device

An optical assembly comprising:

• a common carrier;
• a plurality of first chip groups, each first chip group comprising at least two similar luminescence diode chips;
• a plurality of second chip groups, each second chip group comprising at least two similar luminescence diode chips, wherein the first and second chip groups are arranged planar along a regular grid of first unit cells on a main surface of the common carrier;
• and
• an optical element arranged downstream of the first and second chip groups with respect to a main radiation direction,
• wherein the luminescence diode chips of the different chip groups are configured to emit electromagnetic radiation of different wavelength characteristics,
• wherein the luminescence diode chips within a chip group are arranged side by side and emit in the same spectral region,
• wherein at least one luminescence diode chip from one of the first chip groups and at least one luminescence diode chip from one of the second chip groups are assigned to each of the first unit cells,
• wherein subunits of the optical element are arranged in openings of a mask, and
• wherein the optical element is configured to combine light emitted by the luminescence diode chips of the chip groups into second unit cells in an extraction plane in such a way that at least one second unit cell has an area which is less than or equal to an area of one of the first unit cells.
