The present invention relates to a transparent plate (34) comprising a top surface (34b) and a bottom surface (34a), wherein said top surface (34b) is to be oriented toward the user and said bottom surface (34a) is to be oriented toward a light source (22, 27), and wherein said top surface (34b) is to be concealed by a masking means (28) that renders at least a portion of said transparent plate (34) opaque. Said transparent plate (34) is to receive a luminous flux (32) on the bottom surface (34a) thereof, a portion of said luminous flux (32) being propagated by being reflected into the body of said plate (34) so as to form a leakage luminous flux (32r). Said transparent plate (34) further comprises, on the bottom surface (43a) thereof, a means (40) located at least in one area, said means (40) making it possible to reduce the brightness of the leakage luminous flux (32r) while the latter passes through said area.
