1. Display block comprising:
an optoelectronic circuit comprising light-emitting diodes of at least two display pixels and having a first surface of emission of the light radiations of the light-emitting diodes; and
diffusing structures covering the optoelectronic circuit, each diffusing structure being in contact with a respective portion of the first emission surface associated with a respective display pixel among the display pixels and having a second surface of emission of the light radiations of the light-emitting diodes of said respective display pixel, the ratio of the sum of the areas of the second emission surfaces to the area of the first emission surface being greater than 2, wherein said respective portion of the first emission surface is not centered with respect to the second emission surface, and wherein the display pixels of the optoelectronic circuit are contiguous and wherein the first emission surface is centered with respect to the surface formed by the second emission surfaces.
