Vehicular display device

A vehicular display device for use with a vehicle that has an instrument panel, the vehicular display device comprising:

• a display unit that displays visible information;
• a light projection unit that includes a reflection member which reflects light containing the visible information displayed on the display unit and projects the reflected light to a predetermined observation region to display the visible information as a virtual image;
• a light path adjustment mechanism that switches an imaging position of the virtual image visually recognizable at the observation region between at least two positions arranged in an upward and downward direction;
• an illuminance detection unit that detects an intensity of external light affecting visibility of the virtual image;
• and
• an imaging position control unit that controls the light path adjustment mechanism to change the imaging position of the virtual image to a first position that overlaps with a portion of the instrument panel, at which the virtual image is less influenced by the external light, or to a second position that is spaced away from the instrument panel, at which the virtual image is easily influenced by the external light, depending upon a magnitude of the illuminance detected by the illuminance detection unit.
