Anti-dazzling optical laminate

Abstract

There is provided an anti-dazzling laminate which has anti-dazzling properties, has a high level of transparency by virtue of freedom from a milky-white impression caused by light diffusion, and can realize excellent black color reproducibility and scintillation preventive properties. The anti-dazzling laminate is an optical laminate comprising a light transparent base material and an anti-dazzling layer provided on the light transparent base material, wherein the outermost surface of the anti-dazzling layer has a concavoconvex shape, and the optical laminate satisfies the following requirements: Ha is more than 0% and less than 8%, Hi is more than 0% and not more than 6%, and Hi / Ha is not less than 0.013 and less than 0.8, wherein Ha represents the whole haze value of the optical laminate; and Hi represents the internal haze value of the optical laminate.

Description

Anti-glare optical laminate Associate application This application is based on Japanese Patent Application No. 2007-70831 and claims priority under the Paris Treaty. Therefore, the description of this application also includes all the content disclosed in the description of this patent application. technical field The present invention relates to an antiglare optical laminate used for displays such as CRTs, PDPs, and liquid crystal panels. Background technique In an image display device such as a cathode ray tube display device (CRT), a plasma display device (PDP), an organic or inorganic electroluminescent display device (ELD), a field emission display device (FED), or a liquid crystal display device (LCD), it is required to prevent The reflection of external light or the reflection of the image causes a decrease in contrast and a decrease in visibility. Therefore, in order to reduce image reflection or reflectance using the principle of light scattering or optical i...
