Abstract: A display device for a vehicle includes: a dial plate having an indicator portion corresponding to vehicle information on a viewing side; an image display panel disposed on a back side of the dial plate opposite to the viewing side to luminescently display an image; and a light transmissive display plate that includes a reflective portion disposed on the viewing side of the dial plate to reflect a light from a light source to the viewing side. A region of the dial plate, which faces the image display panel, is set to have a light transmission property to transmit the image of the image display panel through the region of the dial plate.

Abstract: A display device for a vehicle includes: a display unit; a light guide plate disposed on a viewing side of the display unit and having translucency; and a light source unit that causes a light source light to enter inside of the light guide plate through an outer peripheral portion of the light guide plate. The light guide plate includes a reflecting portion having a plurality of reflecting elements to reflect the light source light from the light source unit to the viewing side. The reflecting element has a reflective curved surface formed in a curved surface shape to face the outer peripheral portion where the light source light is incident.
