PURPOSE:To shield electromagnetic noise from the back light completely and to use even a non-transparent conductive member by providing conductivity to a diffuser arranged to a front face of a casing in which the back light is contained. CONSTITUTION:A conductive material 15 is provided to a diffuser 3 arranged to a front face opening of a metallic casing 1. Thus, even when a high voltage of the back light 2 is switched at a high frequency, electromagnetic noise radiating from the back light 2 is shielded and the effect of the diffusion plate diffusing the light from the back light 2 and the effect of the electromagnetic filter are made compatible. Thus, it is not always required to use a transparent material for the conductivity provision member. |
