Head-up display device

A head-up display device comprising:

• a display unit disposed in a vehicle and configured to reflect display light reflected off a reflecting member toward an eye point side to display a virtual image in a display region on the reflecting member, the display light being emitted toward the reflecting member, the reflecting member being capable of transmitting light;
• a housing equipped with the display unit and including an opening disposed facing the reflecting member, the housing being configured to allow the display light to pass through the opening, the display light traveling from the display unit to the reflecting member;
• a transparent cover configured to close the opening and to transmit the display light traveling to the reflecting member;
• and
• a display controller configured to control the display unit, wherein
• the display unit includes a display device accommodated inside the housing and configured to be controlled by the display controller to emit the display light,
• the transparent cover is arranged at the opening in such a manner that, as the display light emitted by the display device and incident on the transparent cover is closer to the eye point, an incident angle of the display light incident on the transparent cover is greater,
• the display region is divided into a first divided region and a second divided region differing from the first divided region, the second divided region being disposed above the first divided region in a vertical direction, and
• when displaying a design image displayed by the display light in the second divided region by controlling the display device, the display controller is configured to perform blurring processing of displaying at least an upper side of the design image in the vertical direction in a blurred manner.
