WIPO Patent Application WO/2018/190282
Kind Code:
A1
Abstract:
Provided is a light adjusting device capable of adjusting light in a continuum.
A first polarizer (20), a first pattern phase difference film (30a) and a second pattern phase difference film (30b) and a second polarizer (22) are stacked in this order, and the relative positions of the first pattern phase difference film (30a) and the second pattern phase difference film (30b) are moved in a uniaxial direction (t). The first pattern phase difference film (30a) and the second pattern phase difference film (30b) are formed with a stripe-shaped pattern in which two phase difference regions, of which at least one of a phase difference value and a slow axis direction differ from one another, are disposed alternately with the same width, where said width is at least equal to 1 μm and at most equal to 500 μm, wherein a long-side direction of the stripe-shaped pattern has an inclination relative to the uniaxial direction (t) in a range greater than 0° and less than 90°.
