Display device, organic light emitting diode display, and manufacturing method of sealing substrate

An organic light emitting diode display comprising:

• a substrate;
• a display unit formed over the substrate and comprising a common power line and a common electrode;
• a sealing substrate secured to the substrate by a bonding layer, and comprising a composite member and an insulating member;
• a first conductive wire member and a second conductive wire member, each of which consecutively pass through at least two points of the insulating member, and are secured to the insulating member;
• a first conductor formed over the inner and outer surfaces of the sealing substrate, and keeping in an electrically conductive state through the first conductive wire member such that a first electrical signal is applied to the common power line through the first conductor;
• and
• a second conductor formed over the inner and outer surfaces of the sealing substrate, and keeping in an electrically conductive state through the second conductive wire member such that a second electrical signal is applied to the common electrode through the second conductor.

A manufacturing method of a sealing substrate, the method comprising:

• providing a lamination structure including a composite member and an insulating member, wherein the lamination structure comprises a first surface and a second surface facing away from the first surface;
• disposing a first metal layer over the first surface of the lamination structure and a second metal layer over the second surface of the lamination structure;
• and
• providing electrical conduction of the first metal layer and the second metal layer by passing a conductive wire member through the first metal layer, the unfinished insulating member, and the second metal layer.
