  • Publication number: 20220073425
    Abstract: The present invention relates to a chemically strengthened glass with a film, including: a chemically strengthened glass having a pair of main surfaces opposing each other; and a film formed on at least one of the main surfaces of the chemically strengthened glass, in which the chemically strengthened glass has two or less interference fringes observed under stress measurement utilizing surface propagation light having a wavelength of 365 nm, and the film has a refractive index lower than a refractive index of the chemically strengthened glass.

  • Publication number: 20210371330
    Abstract: An antifouling layer-attached glass substrate includes a glass substrate having a pair of main surfaces facing each other, and an antifouling layer formed on or above at least one main surface of the glass substrate. At the time of measuring an absorbance inside the antifouling layer-attached glass substrate by a Fourier transform infrared spectrophotometer according to ATR method (Attenuated Total Reflection) from a surface on a side where the antifouling layer is formed, in the case where an absorbance value at 3,955 cm?1 is set to 0.10, a value (H2O absorbance) obtained by subtracting, as a base, the absorbance value at 3,955 cm?1 from a peak value of an absorbance peak which appears around 3,400 cm?1 is 0.010 or more.

  • Publication number: 20200290917
    Abstract: A 3D cover glass, having a polygonal shape in a plan view which corner part may comprise a rounded portion, and containing a central part being flat plane, and curved parts each with a three-dimensional curved surface having a curvature radius of 100 mm or less on peripheries of at least two of the sides of the polygonal shape, wherein the 3D cover glass shows the maximum value of retardation per 1 mm thickness being 16 nm/mm or less when measured by irradiating a light having a wavelength of 543 nm onto the central part orthogonally.

  • Publication number: 20200239360
    Abstract: The present invention relate to a transparent substrate laminate (10) having a transparent substrate (12), an antireflection layer (14) and an antifouling layer (16) in this order, the antireflection layer (14) contains a low-refractive index layer (142) and a high-refractive index layer (144) laminating alternately, the antifouling layer (16) contains a fluorine-containing organic compound, and when washing with ethanol and washing with a fluorine solvent under specific conditions are carried out on the antifouling layer (16) in this order, the antifouling layer (16) satisfies a ratio (i)/(ii) being more than 1 in which (i) represents a fluorine amount after the washing with ethanol and (ii) represents a fluorine amount after the washing with the fluorine solvent, and in which the fluorine amount (F amount) is measured by using an X-ray fluorescence instrument (XRF).
