LIGHT-EMITTING DEVICE, MANUFACTURING METHOD OF THE SAME, ILLUMINATING DEVICE AND DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a highly reliable light-emitting device which inhibits potential drop due to resistance of an upper electrode; to provide a highly reliable light-emitting device capable of forming an EL layer and an upper electrode without using a metal mask; and to provide an illuminating device and a display device to which such light-emitting device is applied.

SOLUTION: A configuration in which auxiliary wiring for assisting conductivity of an upper electrode is provided on a substrate side is focused. The conductive auxiliary wiring included in a light-emitting device is provided on the substrate, and formed such that a part of a side face protrudes in a horizontal direction with respect to the substrate. Further, an EL layer formed in a region including a lower electrode layer and the auxiliary wiring is physically divided by the auxiliary wiring. An upper electrode layer similarly formed may be electrically connected with at least the part of the side face of the auxiliary wiring. Still further, such auxiliary wiring may be applied to an illuminating device and a display device.
