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.

Abstract: There are provide a liquid composition for forming a silicon oxide-based cured coating film by the sol-gel method, the liquid composition having excellent storage stability and being capable of forming a coating film excellent in durability, in particular, alkali resistance even after long-term storage. A liquid composition applied on a surface of a substrate and cured by heating to form a coating film, contains: a matrix component containing a hydrolyzable silicon compound whose content is 20 to 60 mass % as a SiO2 content when silicon atoms contained in the matrix component are converted into SiO2 to the total solid content amount in the liquid composition; a functional component containing an ultraviolet absorbent and an infrared absorbent; water; and an acid thermally decomposing at 80° C. or higher and a temperature of the heating or lower, wherein a pH increases between before and after the thermal decomposition of the acid.
