Abstract

PURPOSE:To observe a display plane in the distortion-less state even when an enlarging lens has distortion by forming the display plane so as to cancel the distortion of the enlarging lens. CONSTITUTION:A magnifying display device 4 is provided with a housing 6 with built-in instruments 5 and a cover 8 protecting an enlarging lens 7 located at the front side of the instruments 5 and mounted on the housing 6. The instruments 5 are provided with an instrument 9 having a display surface 9a for displaying information such as a speed and the rotating speed of an engine and back lights 10, 10 provided on the rear side of the instrument 9 and illuminating the display surface 9a by transmission. When the enlarging lens has pincushion type D or barrel type distortion E, e.g. if the distortion of the enlarging lens is the pincushion type D, the display surface 9a is set so as to give the barrel type distortion E and if the distortion of the enlarging lens is the barrel type E, the display surface 9a is set so as to give the pincushion type distortion D.
