Abstract

There is provided a light-emitting display device which is resistive to shock and vibration and a display switching method comprising: a forward transparent plate having a light scattering portion for a predetermined design pattern relative to a surface direction thereof, a backward transparent plate having a light scattering portion for a predetermined design pattern relative to a surface direction in which the second-mentioned design pattern is different from the first-mentioned design pattern of the light scattering portion of the forward transparent plate, a light source for the forward transparent plate for supplying incidence of light into the forward transparent plate from an end surface of the forward transparent plate, and an other light source for the backward transparent plate for supplying incidence of light into the backward transparent plate from an end surface of the backward transparent plate, so that switching is made from and to emitting and quenching of the backward transparent plate. At the time of luminescence (emitting), the design pattern of the backward panel is synthesized and deleted at the time of quenching.
