The invention relates to a projection device (22), in particular for an instrument panel (26) of a vehicle (20), comprising a projector (30) and a display surface (24). The projector and the display surface are arranged in such a way that light (32) emitted by the projector for a real image representation (36) is guided onto the display surface. The display surface has at least one holographic element (34). Furthermore, the display surface has a first region (40) having a first transparency and a second region (42) having a second transparency, the first region having a lower transparency thanthe second region. The display surface is arranged such that the first region is arranged between an observer (28) of the display surface and the instrument panel and the second region is arranged atleast partially above the instrument panel for the observer of the display surface.

    提出了一种尤其是用于车辆(20)的仪表板(26)的投影设备(22),投影设备具有投影仪(30)和显示面(24),其中,投影仪和显示面如此布置,使得用于真实图像展示(36)的、由投影仪发射的光线(32)被引导到显示面上。显示面具有至少一个全息元件(34)。此外,显示面具有第一区域(40)和第二区域(42),其中,第一区域具有第一透明度,并且,第二区域具有第二透明度,其中,第一区域具有比第二区域更小的透明度。显示面如此布置,使得第一区域布置在显示面的观察者(28)和仪表板之间并且第二区域对于显示面的观察者来说至少部分地布置在仪表板上方。
