Abstract
Display assembly 1 comprising, on the one hand, a glass-ceramic plate 2 of the lithium aluminosilicate type, the optical transmission of which for a thickness of 4 mm is between 0.2% and 4% for at least one wavelength between 400 and 500 nm and, on the other hand, a luminous device 4, characterized in that the luminous device 4 comprises at least one polychromatic light source 5 having at least a first emission of nonzero intensity at said wavelength between 400 and 500 nm and at least a second emission of more than 500 nm, and such that the positioning of said source 5 is designed to allow display through said glass-ceramic plate 2.
