An optical device is disclosed herein. In some embodiments, an optical device includes an active liquid crystal element, wherein the active liquid crystal element comprises two base layers, an active liquid crystal layer disposed between the two base layers, wherein the active liquid crystal layer includes a liquid crystal compound and is capable of switching between first and second oriented states, and a hard coating layer formed on one of the base layers, wherein the hard coating layer is formed on an active liquid crystal layer-facing surface or an opposite surface of the base layer, and wherein the hard coating layer having a thickness of 2 &#x3bc;m or more. The optical device is capable of varying transmittance, and can be used for various applications such as eyewear, for example, sunglasses or AR (augmented reality) or VR (virtual reality) eyewear, an outer wall of a building or a vehicle sunroof.

Optical device

A gas barrier film with a protective layer including inorganic particles is provided. A gas barrier effect of the gas barrier film is improved by including inorganic nanoparticles in a protective layer when a protective coating is performed to protect a gas barrier layer.

Gas barrier film with protective coating layer containing inorganic particles

The present application relates to gas barrier film having excellent adhesive strength and a method of manufacturing the same. Particularly, the present application is directed to providing a gas barrier film having excellent adhesion performance between an inorganic layer and a protective coating layer under harsh conditions by protective coating layer including inorganic nano particles surface-modified with organic silane on the inorganic layer.

Gas-barrier film and method of manufacturing the same

The present invention relates to a transparent electrically-conductive film comprising a substrate having a refractive index of n1, a first coating layer having a refractive index of n2, a second coating layer having a refractive index of n3, and an electrically-conductive oxide layer having a refractive index of n4 in a sequentially laminated form, wherein said refractive index of each layer complies with n1&#x2266;n3&#x3c;n2&#x3c;n4, and a method of preparing the same. The transparent electrically-conductive film according to the present invention has especially excellent color feeling and mechanical property as well as excellent transmittance.

Multilayer structured transparent electrically-conductive film and method of manufacturing the same

Disclosed are a negative C-type compensation film and a method of preparing the same. The negative C-type compensation film includes a) a base layer, and b) a polymer layer comprising polyarylate prepared by a method comprising the step of copolymerizing divalent phenols, divalent aromatic carboxylic acid halides, and allyl bisphenol derivatives, the base layer and the polymer layer being sequentially layered. The compensation film is capable of being used for the negative C-type compensation film without a stretching process, significantly reduces the thickness of the compensation film, and has significantly improved interlayer adhesion force in a multilayer structure.
