Abstract:
Deterioration of the whole electroluminescence layer which is caused by moisture penetration through the electroluminescence layer because of a pinhole in an electrode is prevented. A plurality of island-shaped electroluminescence layers are provided. That is, an electroluminescence layer is divided into plural layers. In addition, the plurality of island-shaped electroluminescence layers are interposed between a pair of common electrodes. Accordingly, even when moisture penetrates into one of the island-shaped electroluminescence layers, moisture does not penetrate into another of the island-shaped electroluminescence layers.
