[origin: FR2755530A1] The invention concerns a display device comprising a lighting source emitting a radiation Is and a spatial modulator lighted by the radiation Is, said modulator consisting of a matrix of N x M elemental pixels (Xi,j) of dNxdM dimensions, the pixels Xi,j and Xi+1,j being separated by a step pN. The device further comprises, means for collimating the radiation Is in each pixel and the step pN is greater by at least one order of magnitude than the dimension dM. The invention is applicable to flat television screen.
