    摘要: A substrate on which a specific type spacer is formed, a substrate comprising an alignment film formed on the spacer, and an optical device using such a substrate are disclosed herein. By controlling the shape of the spacer formed on the substrate, even when the alignment film is formed on the top of the spacer and the orientation treatment is performed, the uniform orientation treatment can be performed without any influence by the step or the like of the spacer, whereby a substrate or the like capable of providing a device having excellent optical performance can be provided.

    摘要: A substrate on which spacers are disposed in a certain arrangement state and an optical device using such a substrate are provided. A plurality of spacers are irregularly disposed on a substrate depending on a predetermined rule, so that overall uniform optical characteristics can be ensured without causing a so-called moire phenomenon or the like, while the spacers maintain the uniform cell gap in the construction of the optical device.

    摘要: A light modulation device is disclosed herein. In some embodiments, a light modulation device includes a first polymer film substrate having a first surface and a second surface, an adhesive layer or pressure-sensitive adhesive layer disposed on the first surface of the first polymer film substrate, a second polymer film substrate having a first surface and a second surface, a liquid crystal alignment film disposed on the first surface of the second polymer film substrate, a −C plate; and a light modulation layer containing a liquid crystal compound. The light modulation device has excellent optical properties including transmittance-variable characteristics through characteristic control and proper arrangement of a compensation film, and being applicable to various uses by controlling inclination angle light leakage in a black mode.
