Abstract: A resin sheet which has a base layer containing particles dispersed therein, is thin and lightweight, and has excellent mechanical strength and light-diffusing properties; a resin sheet containing dispersed particles which is obtained by superposing a reflecting layer or an inorganic gas barrier layer on that resin sheet; a resin sheet containing dispersed particles which is obtained by superposing a color filter layer on that resin sheet; processes for producing the resin sheet having a color filer layer; and liquid crystal displays employing those resin sheets. One of those resin sheets has a hard coat layer, an epoxy resin layer containing, per 100 parts by weight of the resin, up to 200 parts by weight of a diffuser having a refractive index different from that of the epoxy resin and having an average particle diameter of from 0.

Abstract: An epoxy optical sheet having a thickness of 500 &mgr;m or less, a high thickness accuracy, a small retardation and an excellent heat resistance; and a process by which the optical sheet can be efficiently produced.

Abstract: 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.

Abstract: A liquid crystal display device having a resin substrate wherein a transparent resin plate has at least a conductive layer via a transparent layer with a lower refractive index than the resin plate, and a liquid crystal display panel including at least a liquid crystal cell with a liquid crystal carried between a visible side substrate and a back side substrate that are disposed with electrodes on their substrates opposed to one another. One or both of the visible side substrate and the back side substrate is or are the resin substrate.

Abstract: A cured resin plate which is reduced in undulation and has excellent flatness even when having a thickness of 100 &mgr;m or larger or a size exceeding 2 inches; and a process for efficiently mass-producing the resin plate. The process comprises spreading a resinous coating fluid A on a support (5) having a smooth surface to form an unsolidified or solidified coating layer, spreading thereon a resinous coating fluid B which is the same as or different from the coating fluid A to form two or more superposed layers of the coating fluid B, and solidifying the layers (12, 22, and 42) separately or simultaneously to thereby form superposed resin layers (1, 2, and 4) adhered to each other which comprise two or more adjacent cured resin layers (1 and 2). The multilayered resin plate comprises superposed layers adhered to each other which are composed of a thermoset epoxy resin layer and superposed thereon a thermoset epoxy resin layer having a smaller thickness than that layer.

Abstract: A resin substrate for optical use is described, which comprises a multilayer structure (5, 6, 7) having a surface roughness Ra of 0.8 nm or lower on at least one side and having an average thickness of from 100 to 800 &mgr;m.
