• first reflecting means for reflecting light of a displayed image toward a first reflective area of said final reflecting means;
• second reflecting means for transmitting a part of light of the displayed image and reflecting the remainder of the light toward a second reflective area of said final reflecting means, said second reflecting means being located between said first reflecting means and said displaying means, said second reflective area being adjacent to said first reflective area, and said second reflecting means being translucent;
• first shutter means for controlling transmission/non-transmission of the light of the displayed image reflected by said first reflecting means;
• and
• second shutter means for controlling transmission/non-transmission of the light of the displayed image reflected by said second reflecting means, wherein
• one of said first shutter means and second shutter means is opened and the other thereof is closed according to each image selectively displayed by said displaying means, and the displayed image transmitted by the first shutter means or the second shutter means is reflected by said first reflective area or said second reflective area so that a driver can visually recognize the displayed image as a virtual image ahead of a windshield.
