1. A display panel comprising a plurality of semiconductor crystals, each crystal having at least two regions of opposite conductivity forming an electroluminescent junction, said crystals being situated at the bottoms of cavities for reflecting light emitted by said crystals during operation of the display panel, said cavities being formed in strips of material and being disposed according to a previously chosen configuration, and each cavity having at least two metallic connection pads made respectively to contact the two regions of the semiconductor crystal situated at the bottom, characterized in that each of the strips comprises a first and a second row of half-shells disposed in a back-to-back arrangement and producing complementary cavity portions, the half-shells of the first row comprising, at their bottoms, supports and the first connection pads for the semiconductor crystals, and the half-shells of the second row comprising, at their bottoms, metallic contact pads constituting the second connections for said crystals, and in that at least two identical strips are insulated from each other by an insulation material, the two identical strips being associated such that the identical strips form a series of cavities.
