| http://www.w3.org/ns/prov#value | - Alkaline metals such as sodium are contained in an EL layer formed on the final TFT. In other words, the first passivation film 41 works as a protecting layer so that these alkaline metals (mobile ions) do not penetrate into the TFT. Note that alkaline metals and alkaline-earth metals are contained in the term ???alkaline metal??? throughout this specification.
