Title:
TRANSMISSION TYPE POLARIZING ELEMENT, AND COMPLEX POLARIZING PLATE USING THE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2008/018247
Kind Code:
A1
Abstract:
Provided is a transmission type polarizing element (1), which is constituted
to comprise a dielectric substrate (3) having such a structure on the surface
of its one side that a plurality of ridges (2) of an angular section are arranged
in parallel, a thin film (4) made of an optically absorptive substance and formed
on the surface of the angularly sectional ridges (2), and a first dielectric substance
layer (5) for covering such a surface of the thin film (4) made of the optically
absorptive substance as is located on the opposite side of the dielectric substrate
(3). This transmission type polarizing element (1) transmits such a TM polarizing
component of the light normally incident on the dielectric substrate (3) that
the vibration direction of a magnetic field is identical to the longitudinal
direction of the ridges (2), but absorbs a TM polarizing component having the
same vibration direction of the magnetic field as the longitudinal direction
of the ridges (2). By the convenient constitution, therefore, it is possible
to provide the transmission type polarizing element, which can be used as the
polarizing plate having little return light but an excellent durability.
