PROBLEM TO BE SOLVED: To provide an display unit for vehicles in which a sufficient display luminance can be obtained with a relatively small-scale light source by reducing the loss of the light emitted by the light source, a relatively inexpensive optical system can be used, without having to use a prismatic mirror as an optical system for scanning the light emitted by the light source, signal processing can be performed inexpensively, and degradation in the display quality due to vibration can be suppressed. SOLUTION: The display unit for vehicles is equipped with an LED array 1, a prism body 2 consisting of a transparent body, a motor 6 for rotating the prism body 2, a lighting pattern which corresponds to the lighting signal of the LED array 1 and is disposed on a timing plate 7, a photointerruptor 8, which reads the lighting pattern and converts the lighting pattern to a lighting timing signal, a timing signal generating section 41, and a display image control circuit 43 which controls lighting/non-lighting of light-emitting elements, made to synchronize with the lighting timing of the prism body 2 by the image information to be displayed.
