Abstract:
A curved transparent substrate includes an alkali-free base layer having a curved shape and a compression applying layer compression applying layer which is disposed on a surface of the alkali-free base layer and applies a compression to the alkali-free base layer where an alkali ion content of the compression applying layer is greater than an alkali ion content of the alkali-free base layer.
