ABSTRACT:
A thin film EL device is disclosed which includes a hole-injecting electrode, an electron-injecting electrode paired with the hole-injecting electrode, and a functional layer provided between the hole-injecting electrode and the electron-injecting electrode and emitting light by application of an electric field produced by the electrodes. The electron-injecting electrode contains at least two or more different metals having different work functions and a capturing substance for capturing a low work function metal, which is a metal other than a highest work function metal among the above-described metals, in its ionic state. This configuration prevents deterioration of the low work function metal, increasing the luminance and lifetime of the device.
