Abstract
A light-emitting device (100) includes a substrate (110), a first electrode (120), an auxiliary electrode (124), an insular conductive layer (126), an insulating layer (170), an organic layer (130), and a second electrode (140). The first electrode (120) is formed over the substrate (110), and is formed using a transparent conductive material. The auxiliary electrode (124) is formed over the first electrode (120). The conductive layer (126) is formed over the first electrode (120), and is formed of the same material as that of the auxiliary electrode (124). The insulating layer (170) is formed over a portion of the first electrode (120), and covers the auxiliary electrode (124) and the conductive layer (126). The organic layer (130) is formed over the first electrode (120), and the second electrode (140) is formed over the organic layer (130).
