Abstract

A vehicle display device includes an indicator that luminously displays a display image on its screen by lighting and stops the luminous display of the display image by extinction, and a display panel that includes a light shielding part on a rear surface of the display panel. The light shielding part light-shields a surrounding part of a transmitting window, through which an image light of the display image is transmitted to be capable of being visually recognized from a front side. A transmission region of a front surface of the display panel that is located at least on the front side of the transmitting window is occupied by a planar part that is formed in a flat surface shape along the screen, and a plurality of projecting surface parts that project from the planar part into a curved projecting surface shape. An area occupancy of the planar part at the transmission region is adjusted to be equal to or larger than an area occupancy of all the plurality of projecting surface parts at the transmission region.
