Abstract
A hole injection layer and a second electrode are both formed to be continuous above a first electrode and above an auxiliary wiring. The hole injection layer contains a tungsten oxide. An UPS spectrum, obtained from a UPS measurement, has a protrusion appearing near a Fermi surface and within a region corresponding to a binding energy range lower than a top of a valence band, and the tungsten oxide satisfies a condition, determined from an XPS measurement, that a ratio in a number density of atoms other than tungsten atoms and oxygen atoms to the tungsten atoms does not exceed 0.83.
