Title:
IMAGE DISPLAY DEVICE, IMAGE GENERATING DEVICE, AND TRANSPARENT SPATIAL LIGHT MODULATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/109115
Kind Code:
A1
Abstract:
An image display device (100) is provided with (A) an image generating device (111) provided with a light source (160) and a transparent spatial light modulating device (150) formed by disposition of pixels (152) in a two-dimensional matrix shape, and (B) a light guiding means (120) that guides light from the light generating device (111) so as to output the light toward the eyes (21) of an observer (20). The transparent spatial light modulating device (150) is provided with a microlens array (170) having microlenses on the light output side that correspond to each of the pixels. Letting ωin be the solid angle of incidence of light incident to the pixels from the light source (160) and ωout be the solid output angle of light passing through the pixels and output by the microlenses corresponding to the pixels, ωout > ωin is satisfied.
