Abstract:
1. A display device comprising: a display device substrate having an external connection terminal and a lower-layer wiring running below the external connection terminal, an external connection component, and a conductive member that electrically connects the display device substrate and the external connection component, wherein the external connection component has a connection portion connected to the external connection terminal via the conductive member; the external connection terminal is in contact with the conductive member; the display device substrate further has an interlayer dielectric formed at a layer below the external connection terminal, a wiring connection portion that is formed at a layer below the interlayer dielectric and that is connected to the external connection terminal by way of a first connection hole in the interlayer dielectric, and a higher-layer wiring that does not overlap the connection portion, in a plan view of the display device substrate; the higher-layer wiring is electrically connected to the external connection terminal via the wiring connection portion, overlaps the external connection component, in a plan view of the display device substrate, includes the same conductive layer as a conductive layer that makes up the external connection terminal, and is connected to the lower-layer wiring by way of a second connection hole in the interlayer dielectric; and the first and second connection holes are disposed outside a region at which the connection portion and the conductive member overlap each other, in a plan view of the display device substrate.
