Title:
DISPAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/132289
Kind Code:
A1
Abstract:
A display device (1) comprises: a light source (101) which outputs a laser beam; an illumination optical assembly (102) which emits the laser beam as an illumination light; a spatial modulation element (103) which diffracts the illumination light by displaying a diffraction pattern; and a mounting unit (111) for mounting on a user's head. When the mounting unit (111) is in a state of being mounted on the user's head, a location relation between the spatial modulation element (103) and an eyeball assumed location (191a) which is assumed as a location of an eyeball (190) of the user is fixed. The diffraction light being diffracted by the diffraction pattern thus reaching the eyeball assumed location (191a), the spatial modulation element (103) displays a diffraction pattern as a diffraction pattern such that a virtual image is displayed to the user.
