摘要： An epoxy optical sheet comprising a hardened sheet of an epoxy resin and another resin layer formed on one side thereof. The sheet has a retardation of 5 nm or less, an average thickness of 500 &mgr;m or less, a thickness accuracy of ±10% or less, a glass transition temperature of 170° C. or above, and a smooth surface. The epoxy optical sheet is made by a continuous process which comprises: successively forming a strippable resin layer on a support having a smooth surface; successively spreading an epoxy resin coating solution comprising an epoxy resin, a hardener, a hardening accelerator, and a leveling agent, on the resin layer in the form of a sheet; followed by a hardening treatment, thereby forming a hardened sheet adhering to the resin layer; and, at the same time, recovering the hardened sheet together with the resin layer from the support.

摘要： A resin sheet that is unlikely to be affected by heat and allows prevention of the occurrence of a crack is provided. A glass fiber cloth-like material is dipped into an epoxy resin solution and subjected to curing, thereby obtaining an epoxy resin-based sheet including the glass fiber cloth-like material. The resin sheet has a haze value of 10% or lower, and preferably, has a light transmittance of 88% or higher, an in-plane retardation of not more than 2 nm, a retardation in a thickness direction of 40 nm, and a surface roughness of not more than 2 μm.

摘要： A resin sheet which comprises a base layer containing particles dispersed therein and hence has excellent dimensional stability; a resin sheet which comprises a base layer containing particles dispersed therein and hence has excellent light diffusion properties; resin sheets which comprise either of those resin sheets containing dispersed particles and a reflecting layer, inorganic gas barrier layer, and color filter layer respectively superposed thereon; and a liquid crystal display using any of these resin sheets containing dispersed particles. Some of the resin sheets containing dispersed particles comprise a base layer comprising a thermoplastic resin or thermoset resin and dispersed therein an inorganic oxide having an average particle diameter of 1 to 100 nm, the amount of the inorganic oxide being 0.1 to 23% by weight based on the weight of the base layer.

摘要： Resin sheets which are thin and lightweight and have an antiglare function for preventing the so-called ghost phenomenon in which an illuminating light, such as fluorescent light or sunlight, or part of the surrounding objects, e.g., the keyboarder, is reflected on the display and/or a light-diffusing function for preventing the glittering attributable to an illuminating light or to the built-in backlight in the liquid crystal display; processes for producing the resin sheets; and liquid crystal displays using the resin sheets. One of the resin sheets comprises a gas barrier layer, a base layer, and two hard coat layers respectively as the outermost layers, wherein one of the hard coat layers has recesses and protrusions on the outer surface thereof and at least one of the hard coat layers contains transparent particles.
