Abstract
A display device includes a self-light-emitting image display that has pixels arranged two-dimensionally, micro light-emitting points that correspond to each pixel of the image display and exist in a part of the pixel, and a micro optical element that guides irradiated light from each of the micro light-emitting points arranged two-dimensionally. Optical axes connecting each of the micro light-emitting points and the micro optical element corresponding to the micro light-emitting point substantially intersect in a predetermined point closer than a near point of an eye, and the micro optical element is arranged so as to focus a virtual image of the micro light-emitting point corresponding to the micro optical element in a position that is a least distance of distinct vision or more apart from the predetermined point.
