Abstract: To provide an optical laminate that can sufficiently exhibit the function of a functional material such as an antistatic agent or fine particles in the obtained laminate without using a binder material for fixing the functional material to the substrate, as well as a method for manufacturing the same, there is obtained the optical laminate by step (A1) in which the substrate is coated with a composition (a) containing a solvent capable of swelling or dissolving the substrate and the functional material, step (A2) of drying, and step (A3) of forming a resin layer on the coated substrate.

Abstract: An antistatic laminate is provided that simplifies the production of a polarizing plate and, at the same time, can satisfactorily meets requirements of IPS and VA modes. The antistatic laminate is adapted for use in polarizing plates and comprises a light transparent base material and an antistatic layer provided on the light transparent base material. The antistatic layer is located between the polarizing element of the polarizing plate and a light transparent display site while using a polarizing plate.

Abstract: A vibration control unit in which a rolling element having a first curved surface that is a convex surface is interposed between a first and second members, and the rolling element is allowed rolling with respect to the first member in the first curved surface thereof. The rolling element has a second curved surface that faces the first curved surface and is formed of a curved surface center different from that of the first curved surface. As the rolling element, resulting from an additional force applied on the first and second curved surfaces, rolls with respect to the first member, the second member vibrates with a restoring force determined based on an average curvature radius of the first and second curved surfaces of the rolling element and a distance between curved surface centers of the first and second curved surfaces.
