    Patent number: 6657381
    Abstract: A display device (1) includes a multi-layered structure (10) and a plurality of light-emitting devices (31) mounted on a display surface of the multi-layered structure. The multi-layered structure includes successively stacked first, second and third insulating layers (11, 12, 13) with the first layer on the display surface side, a first conductive layer (21) sandwiched between the first and second insulating layers, and a second conductive layer (2) sandwiched between the second and third insulating layers. Each of the first, second and third insulating layers is formed of such a material that a needle or the like can be stuck into it. Also, each of the first and second conductive layers is a layer of fibers, into which a needle or the like can be stuck.
