Beschreibung
Zusammenfassung:	An electroluminescent (EL) dial 7 for an analog timepiece comprising a flexible transparent substrate 23, an inner layer 24 comprising electrically conductive material adhered to the substrate 23, an EL layer 25 comprising a mixture of electroluminescent material in a binder adhered to the inner layer 24, and an outer layer 27 covering the electroluminescent layer 25 comprising electrically conductive material, the substrate 23 and the layers 24 - 27 comprising a single flexible laminated assembly and having a hole (not shown) therethrough for accommodating the rotatable stem (not shown), and includes a tab portion 28 comprising the substrate 23 and the inner layer 24 extending beyond the EL and outer layers 25 and 26, 27. A dial support member 22 comprising a rigid plate substantially the size and shape of the electroluminescent dial 7 supports the dial on one side of the frame (not shown). An electrical circuit (not shown) causes illumination of the EL layer. A modified form (not shown) utilises a shorter tab and elastomeric connectors for both first and second connectors.
