PACKAGE FILM FOR EL PANEL, ITS MANUFACTURE, AND EL PANEL AND LCD MODULE EMPLOYING THE FILM

摘要

An El panel package film which is, for instance, a PCTFE film or a PET film having a moisture-proof layer. At least one side of the EL panel package film is roughened. The arithmetic mean roughness (Ra) and maximun height (Ry), which are specified by JIS G 0601, are not less than 3 mu m and not less than 10 mu m respectively. The EL panel package film is used as at least the package film on the light-emitting side of an EL panel. Vibration which is caused by the inversion of the polarity of the AC voltage applied to the EL panel is absorbed and diffused by the protrusions of the package film surface. A LCD module has such EL panel as a back light. The noises from the surfaces of LCD cells can be reduced.
