ABSTRACT:
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.
