The present invention relates to a glass plate which is provided with a first main surface, and a second main surface which faces the first main surface. An antiglare portion and a non-antiglare portion are provided to the first main surface. The average lengths (RSm) of elements of roughness curves of the antiglare portion and the non-antiglare portion are respectively 1 &#x3bc;m or higher. The difference between the RSm of the antiglare portion and the RSm of the non-antiglare portion is 100 &#x3bc;m or lower.

Glass plate

A glass sheet composite includes a first glass sheet; a second glass sheet; and a liquid layer sandwiched between the first glass sheet and the second glass sheet. The glass sheet composite has a loss coefficient greater than or equal to 1&#xd7;10at 25&#xb0; C., and an acoustic velocity of longitudinal wave greater than or equal to 5.0&#xd7;10m/s in a sheet thickness direction at 25&#xb0; C. The liquid layer has a viscous coefficient of 1&#xd7;10-1&#xd7;10Pa&#xb7;s at 25&#xb0; C., and a surface tension of 15-80 mN/m at 25&#xb0; C. The liquid layer contains particles whose mean particle diameter is 0.3-1 &#x3bc;m.

Glass sheet composite, diaphragm using the same, and image projection structure

The present invention provides a substrate with an antireflection layer not only which is excellent in the antireflection properties but also which has high water repellency and oil repellency and favorable oil and fat stain removability, and a display device provided with a substrate with an antireflection layer. A substrate with an antireflection layer, which comprises an antireflection layer on at least one surface of the substrate,

Substrate with antireflection layer

Hollow fine particles containing SiOas the main component and containing another metal. The amount of the other metal (calculated as oxide) is 0.2 to 8 parts by mass based on 100 parts by mass of SiO. A coating composition containing the hollow fine particles and a dispersion medium. An article having a coating film including the coating composition formed on a substrate. A process for producing hollow fine particles, which includes (a) precipitating a shell containing SiOas the main component and containing another metal on the surface of core fine particles, to obtain core/shell particles, and (b) dissolving or decomposing the core fine particles of the core/shell fine particles.
