摘要 |
Disclosed is a thin film EL panel having a high reliability. The thin film EL panel is thin, light, and low cost. The present invention provides in a thin film electroluminescent (EL) panel comprising a light permeable base plate, a thin film EL element formed on the base plate and a moisture-proof sheet covered thereon, an improvement residing in that a moisture-absorption sheet is placed between said thin film EL element, and said moisture-proof sheet and said moisture-absorption sheet comprises an organic polymer sheet and silica gel powder dispersed therein in a certain surface density. The present invention also provides in a thin film electroluminescent (EL) panel comprising a light permeable base plate, a thin film EL element formed on the base plate and a moisture-proof sheet covered thereon, an improvement residing in that a moisture-absorption layer is formed on the inside surface of the moisture proof sheet by coating powder having moisture absorption properties. |
