Abstract
An EL display device capable of reducing an average film resistance of an anode in an EL device as well as displaying an image with high definition, and electrical equipment including such an EL display device are provided. A light-shielding metal film 109 is provided on an anode 108 so as to conceal gaps between the pixels. Thus, an average film resistance of the anode 108 in the EL device is reduced. Furthermore, light leakage from the gaps between the pixels can be prevented, resulting in an image display with high definition.
