    摘要： An object of the present invention is to provide a photo-alignable polymer which has excellent coating properties, is capable of suppressing film thickness unevenness, and has excellent upper layer coating properties and good liquid crystal alignment properties after being formed as a layer; a binder composition; a binder layer; an optical laminate; a method for producing an optical laminate; and an image display device. The photo-alignable polymer of an embodiment of the present invention is a photo-alignable polymer having a repeating unit A including a cleavage group capable of decomposing by an action of at least one selected from the group consisting of light, heat, an acid, and a base to generate a polar group, in which the repeating unit A has the cleavage group in a side chain, has a fluorine atom or a silicon atom on a side closer to a terminal than the cleavage group in the side chain, and the photo-alignable polymer satisfies Condition 1 or Condition 2 shown below.
    Condition 1: The photo-alignable polymer further has a repeating unit B including a photo-alignable group, in addition to the repeating unit A.
    Condition 2: The repeating unit A includes a photo-alignable group on a side closer to the main chain than the cleavage group in the side chain.

    摘要： A liquid crystal display device, which includes a first substrate and a second substrate disposed to face each other with a liquid crystal sandwiched therebetween. The first substrate is an electrode-provided substrate having a first electrode and a plurality of second electrodes overlaid on the first electrode via an insulating film, formed on a pixel region on a surface on the liquid crystal side, where one of the first electrode and the second electrodes is a pixel electrode and the other is a counter electrode, having a first liquid crystal alignment film formed on the surface on the liquid crystal side of the first substrate covered with the second electrodes. The second substrate is a substrate having a second liquid crystal alignment film formed on a surface on the liquid crystal side, the second liquid crystal alignment film containing a photosensitive side chain type polymer which develops liquid crystallinity.

    摘要： A fiber-reinforced molding material includes: as essential raw materials, a vinyl ester (A) which is a reaction product of an epoxy resin (a1) having an epoxy equivalent in the range of 180 to 500 and a (meth)acrylic acid (a2); an unsaturated monomer (B) having a flash point of 100° C. or higher; a thermoplastic resin (C); a polyisocyanate (D); a polymerization initiator (E); and carbon fibers (F) having a fiber length of 2.5 to 50 mm. The mass ratio ((A)/(B)) of the vinyl ester (A) to the unsaturated monomer (B) is in the range of 40/60 to 85/15. The molar ratio (NCO/OH) of the isocyanate group (NCO) of the polyisocyanate (D) to the hydroxy group (OH) of the vinyl ester (A) is in the range of 0.25 to 0.85.
