IMAGE DISPLAY AND METHOD FOR EVALUATING GLASS SUBSTRATE TO BE USED IN SAME

摘要

An image display which can display a good image by preventing yellowing of a glass substrate is disclosed. A method for evaluating a glass substrate to be used in such an image display is also disclosed. The image display is constituted using a glass plate having a reflectance of 5 % or less at a wavelength of 220 nm. In the method for evaluating a glass substrate to be used in the image display, the amount of Sn<++> in the glass substrate is analyzed using the reflectance of the glass substrate at the wavelength of 220 nm.
