A vehicle light-adjusting window and a vehicle light-adjusting window system capable of clearly projecting a video are provided. A vehicle light-adjusting window includes a transparent plate, a first conductive film, a light-adjusting layer, a second conductive film, and a projection film, which are arranged in this order.

Vehicle light-adjusting window and vehicle light-adjusting window system

A liquid crystal layer as a member of a liquid crystal element is disposed between a first resin film substrate and a second resin film substrate. A first/second conductive film is attached to one side of the first/second resin film substrate. A blade is inserted into the liquid crystal layer. The blade is moved while being inserted in the liquid crystal layer, thus making an incision in the liquid crystal layer. Then, the incision location is widened in the first resin film substrate and in the second resin film substrate, forming an opening in the surface of the liquid crystal layer. This also forms a space inside the liquid crystal layer, allowing the opening to communicate with the space. Part of an electrode is then inserted into the space of the liquid crystal layer and the liquid crystal layer is bonded with part of the electrode.

Method for attaching electrode to liquid crystal element

A liquid crystal display device having a liquid crystal layer made of a cured product formed by irradiating a liquid crystal composition disposed between a pair of substrates provided with electrodes with ultraviolet light from an ultraviolet irradiation apparatus and at least one of the substrates being provided with a liquid crystal alignment film to vertically align liquid crystal, where the liquid crystal composition contains a curable resin, a bifunctional monomer, a compound of the following formula [1-1a], a compound of the following formula [2-1a] and a monomer having at least one polar group selected from a hydroxy group, a carboxy group and a phosphoric acid group, where the liquid crystal alignment film is obtainable from a liquid crystal alignment treating agent containing a polymer having a side chain structure of the following formula [4-1a] or formula [4-2a]    

Liquid crystal display device

A liquid crystal display device, containing: a pair of substrates provided with an electrode and a liquid crystal layer formed by disposing a liquid crystal composition between the pair of substrates and by irradiating and curing the liquid crystal composition with ultraviolet rays using an ultraviolet irradiation apparatus, wherein at least one of the substrates is further provided with a liquid crystal alignment film to vertically align a liquid crystal, the liquid crystal composition contains a liquid crystal, a curable resin, a bifunctional monomer and a monomer having at least one polar group of a hydroxy group, a carboxy group or a phosphoric acid group, and the liquid crystal alignment film is a liquid crystal alignment film obtained from a liquid crystal aligning agent containing a polymer having a specific side chain structure.

Liquid crystal display element

A liquid crystal display device, whereby transparency when no voltage is applied and scattering properties when a voltage is applied, are good, adhesion between a liquid crystal layer and a vertical liquid crystal alignment film is high, and its lifespan is long even in a severe environment. The liquid crystal display device has a liquid crystal layer formed by disposing a liquid crystal composition containing a liquid crystal and a polymerizable compound between a pair of substrates provided with electrodes, and irradiating and curing the composition with ultraviolet rays by an ultraviolet irradiation apparatus, and at least one substrate is provided with a liquid crystal alignment film to vertically align a liquid crystal, wherein the ultraviolet irradiation apparatus is an ultraviolet irradiation apparatus capable of controlling the irradiation light intensity and wavelength of the ultraviolet rays to be irradiated and the surface temperature of the pair of the substrates.

A door () includes a tabular main body (), a liquid crystal device () which is disposed in an aperture portion formed in the main body (), a handheld portion (A) which is attached to the main body (), and a touch sensor () which is attached to the handheld portion (A). Because the touch sensor () is attached to the handheld portion (A), when a person's hand touches the handheld portion (A), the touch sensor () senses the person's hand. The liquid crystal device () is capable of varying between an invisible state and a visible state reversibly, and is made into a visible state in the case where the touch sensor () senses a person's hand.
