To provide a head-mount display device that can form a virtual image in which luminance unevenness of the virtual image to be observed is restrained.

The head-mount display device 100 includes a light source 14 including a plurality of light-emitting diodes 22; a flat panel display 11 that forms an image on a flat panel; an emission mechanism 10 having a cylindrical case 15; and an eyepiece optical system 13. The flat panel display 11 is fixed inside the case 15 so that the direction of normal line of the flat panel does not coincide with the direction of the center of a pupil and is set inclined. The light source 14 is fixed inside the case 15 so that the emission directions in which light beams are emitted from respective light-emitting diodes 22 coincide with the center direction of the pupil and the distances of respective light-emitting diodes 22 from the flat panel are equal to one another, and a reflecting plate 16 for reflecting the light emitted from the light source 14 is formed in an inner periphery of the case 15 arranged between the light source 14 and the flat panel display 11.
