Problems solved by technology

[0008] However, when a glass fiber cloth is embedded in a cured resin layer to produce a resin sheet for a substrate, since the cured resin layer is composed of two components, glass and resin, there is a possibility of light transmission due to light diffusion. Transient adverse effects
[0009] In addition, in the resin sheet of the above-mentioned structure, irregularities are likely to occur on the surface of the resin sheet due to the shape of the glass fiber cloth, which may adversely affect the light transmittance.

Embodiment 1

[0082] Silica particles (average particle diameter: 15 nm) as inorganic particles are used in such a way that the amount of epoxy resin is 24.6 parts (parts by weight, the same below), which is represented by chemical formula (3) and is uniformly dispersed by sol-gel reaction. 3,4-epoxycyclohexylmethyl-3,4-epoxycyclohexanecarboxylate (trade name "NANOPOX XP22 / 0316", manufactured by Hanse Chemie Co.), stirred and mixed with the following chemical formula (4) Dicyclopentadiene type epoxy resin (trade name "EXA-7230" (epoxy equivalent 259), manufactured by Dainippon Ink Chemical Industry Co., Ltd.) 6.9 parts, 36.2 parts of methyl norbornene dianhydride as a curing agent, as 0.72 parts of tetra-n-butylphosphonium o, o-diethylphosphoric acid dithioester represented by the following chemical formula (5) of the curing accelerator, prepared a ring with a content of silica particles in the cured resin layer of 31.5% by weight.

Abstract

A resin sheet having an excellent light-transmitting property for not lowering the display quality of a display or the like is disclosed The resin sheet is characterized by comprising a resin curing layer wherein a fabric-like body made of glass fibers and inorganic particles are contained in a resin, and by having a haze value of not more than 10%.Resin sheet is reduced in weight and thickness, improved in impact resistance, and suppressed in thermal shrinkage / expansion. Also disclosed are a substrate for displays, display, and substrate for solar cells comprising such a resin sheet.

Description

technical field [0001] The present invention relates to a resin sheet mainly used in a display device, a substrate for a display device having the resin sheet, a display device, and a substrate for a solar cell. Background technique [0002] In liquid crystal display devices, electroluminescence display devices, and the like, it has been proposed to use plastic substrates instead of conventional glass substrates from the viewpoint of weight reduction and thinning of displays and improvement of impact resistance. However, such a substrate is required to have a low coefficient of thermal expansion, and when the linear expansion coefficient is higher than that of glass like a plastic substrate, there are places where shrinkage and expansion due to heat occur, for example, when electrodes are formed or color filters are formed. Offset and other issues. [0003] In particular, in recent years, in liquid crystal display devices, since the display quality of the active matrix driv...
