Title:
OPTICAL ELEMENT AND LIGHT POLARIZING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/066429
Kind Code:
A1
Abstract:
This optical element and light polarizing device are provided with a plurality of optical anisotropic layers in the thickness direction. Each of the optical anisotropic layers is derived from a liquid crystal compound and has an in-plane orientation pattern in which the orientation of the optical axis changes while continuously rotating along at least one in-plane direction. The optical anisotropic layers have regions having different lengths in the one direction until the orientation of the optical axis rotates 180º. At least one of the plurality of optical anisotropic layers has a plurality of pairs of bright lines and dark lines, derived from the orientation of the optical axis, along one direction in a cross-sectional image of a cross-section, cut in the thickness direction along one direction, observed using a scanning electron microscope. The optical anisotropic layers have regions in which the pairs of bright lines and dark lines are inclined at different angles with respect to the normal line of the interface between the optical anisotropic layers.
