Abstract
A wiring line is provided on a TFT layer, in which the wiring line is formed in the same layer and formed of the same material as those of a reflection electrode. The reflection electrode includes a plurality of metallic conductive layers made up of a low resistance metallic material, an oxide-based lower transparent conductive layer provided on a lower surface side of a lowermost metallic conductive layer constituting a lowermost layer, an oxide-based upper transparent conductive layer having light reflectivity and provided on an upper surface side of an uppermost metallic conductive layer constituting an uppermost layer, and an oxide-based intermediate transparent conductive layer provided between the plurality of metallic conductive layers.
