The invention provides an input/output-integrated display device equipped with a means for inputting information through handwriting comprising a protective glass plate arranged as an outermost layer on the observation side of the device, leaving a space between the protective glass plate and a part of the device facing the same. The protective glass plate is a chemically reinforced glass plate prepared by immersing, in a molten salt bath, a glass plate produced according to the floating technique and has a Young's modulus of 71 to 74 GPa and a Poisson's ratio of 0.22 to 0.24 to thus chemically reinforce the same; the protective glass plate has the side serving as the top face upon the production of the glass plate according to the floating technique and the bottom face side opposite to the top face side; the surface compression stress on the top face side is 200 to 650 MPa; the protective glass plate is arranged such that the top face faces the space; and the protective glass plate is deflected towards the bottom face side at a warpage.

Input/output-integrated display device and protective glass plate used therein

The invention relates to a glass plate including (a) a glass substrate having a major surface divided into a central major portion and a peripheral portion surrounding the central major portion; and (b) an oxide film formed on the central major portion by baking a precursory film. The oxide film is not formed on the peripheral portion such that the peripheral portion is free from shrinkage force caused by the baking.

Glass plate with oxide film and process for producing same

The invention relates to an article having a substrate and photocatalytic film covering the substrate. This film contains (1) a film-forming component including ZrO and SiO and (2) TiO crystals dispersed in the film-forming component. These ZrO , SiO and TiO crystals respectively are in amounts of 25-60 wt %, 15-50 wt % and 25-45 wt %, based on the weight of the film. The article is improved in photocatalytic activity, abrasion resistance and chemical resistance by the provision of the film.
