Abstract
A substrate (100) has optical transparency, and a light-emitting unit (140) is formed on the substrate (100). The light-emitting unit (140) includes a first electrode (110), an organic layer (120), and a second electrode (130). The organic layer (120) is located between the first electrode (110) and the second electrode (130). The second electrode (130) extends outside the light-emitting unit (140). At least an end of a portion of the second electrode (130) which is located outside the light-emitting unit (140) is oxidized.
