Abstract: 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 μm or higher. The difference between the RSm of the antiglare portion and the RSm of the non-antiglare portion is 100 μm or lower.

Abstract: 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 1×10−2 at 25° C., and an acoustic velocity of longitudinal wave greater than or equal to 5.0×103 m/s in a sheet thickness direction at 25° C. The liquid layer has a viscous coefficient of 1×10−4-1×103 Pa·s at 25° C., and a surface tension of 15-80 mN/m at 25° C. The liquid layer contains particles whose mean particle diameter is 0.3-1 μm.

Abstract: 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, wherein the antireflection layer contains a silica porous film having fluorinated organic groups, and the surface of the antireflection layer on the opposite side from the substrate has an element number ratio F/Si of at least 1 as obtained from the peak height of F1s and the peak height of Si2p in surface analysis by scanning X-ray photoelectron spectroscopy (ESCA) and has an arithmetic mean roughness (Sa) of at most 3.0 nm.
