DISPLAY DEVICE

A display device is provided in which distortion of a displayed image is suppressed easily. A display device 1 includes a light source 2, a mirror 3, a screen 5, and an optical element 6. A normal line N1 of the optical element 6 at a position where a main light beam X3 is incident is positioned on a side to a light beam F4 at a one-side end of an intermediate image, with respect to the main light beam X3. A normal line N2 of a reflection surface of the mirror 3 is positioned on a side to a light beam F1 at other-side end of the intermediate image, with respect to a main light beam X2 outgoing from the mirror 3. A light outgoing surface P3 of the screen is tilted with respect to a plane P4 vertical to the main light beam X3, in such a direction that an optical path of the light beam F4 at the one-side end of the intermediate image, between the screen 5 and the optical element 6, is shortened.
