A head mounted display device which generates an image using a single image generating unit of a small display device and is capable of simulating a large screen, and an optical system for use in the HMD are provided. The head mounted display device includes a light source for generating and irradiating light, an image generator for generating an image from light irradiated from the light source, an image forming lens unit for primarily forming the image generated by the image generator, a first light branching portion for transmitting and reflecting the image generated by the image generator and branching the image, a first light path converter for converting the traveling path of the image reflected from the first light branching portion, a first reflecting mirror on which the image received from the first light path converter is reflected toward an eye of a user, a second light branching portion, disposed on the light path between the first light path converter and the first reflecting mirror, for changing the traveling path of the incident image, a second light path converter for converting the traveling path of the image having passed through the first light branching portion, a second reflecting mirror on which the image received from the second light path converter is reflected toward the other eye of a user, and a third light branching portion, disposed along the light path between the second light path converter and the second reflecting mirror, for changing the traveling path of the incident image.
