Tempered glass and chemically strengthened glass and having a chemical strengthening glass production process, the chemical and the image display device of chemically strengthened glass

Object of the present invention is to provide a chemically strengthened glass, which can be chemically similar to the conventional process, the strength is reinforced Alice conventional soda lime glass is improved compared, and the step can be reduced by chemically strengthening one embodiment song. The present invention provides a chemical strengthening glass, which is based on the mass percentage of the oxide containing, 65% to 72% SiO2,3.6% ~ 8.6% of Al2O3,3.3% ~ 6% of MgO, 6.5% ~ 9% of CaO, 13% ~ 16% of Na2O and K2O 0 to 0.9%, and (Na2O + K2O) / Al2O3 of 2.2 to 5 by a float forming a chemically strengthened glass obtained, wherein the chemical strengthening SnO2 glass plate thickness (t) of 0.1mm or more and 2mm or less, and the bottom surface of the chemical state of the unground glass strengthening of 6.2μg / cm2 or less (0.1mm≤t≤1mm) or (2t + 4.2) μg / cm2 or less (1mm
