Vehicular display device

Abstract

Provided is a vehicular display device that offers good visibility without causing a passenger to feel uncomfortable. In a bezel that includes a cover portion arranged above a display unit of a vehicular display device and a frame portion enclosing the cover portion, a front-side end portion of the cover portion is arranged at a position lower than a rear-side end portion. As a result, external light is reflected forward. Moreover, a front frame includes a reflecting plate, a semi-transparent output plate covering over the reflecting plate, and a light-collecting portion collecting external light that enters from a front into a space enclosed by the reflecting plate and the output plate. As a result, the front frame is prevented from being darkly reflected onto a front glass.
