Abstract
A vehicular display apparatus includes a light source and a light guide member. The light guide member includes (i) an interior portion that receives light from the light source and (ii) outer faces that reflect the light repeatedly to permit the light to propagate in the interior portion. The light guide member further includes a viewable portion and a light absorption member serving as a light attenuation portion. The viewable portion reflects a part of the light propagating in the interior portion towards a viewer side so as to appear to be luminous. The light absorption member absorbs a part of light reflected by the outer face.
