Title:
OPTICAL DEVICE AND DISPLAY DEVICE PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2015/098184
Kind Code:
A1
Abstract:
An optical device (100) is provided with: a first substrate (10) and a second substrate (20) provided so as to face each other; an optical layer (30) provided between the first substrate and the second substrate; and a first electrode (11) and a second electrode (12) that can be given different potentials from each other. The optical layer includes a medium (31) and shape anisotropic particles (32) having shape anisotropy. The shape anisotropic particles change direction of orientation according to voltage applied to the optical layer. The voltage applied to the optical layer is an oscillating voltage having a first period with a relatively large absolute value and a second period with a relatively small absolute value that alternate.
