Abstract:
A display device having a display surface, comprising:a multi-layered structure comprising first, second and third successively stacked insulating layers, a first conductive layer disposed between said first and second insulating layers, and a second conductive layer disposed between said second and third insulating layers, said display surface being provided by one of opposing major surfaces of said multi-layered structure, said first insulating layer being located closest to said display surface; and a plurality of light-emitting devices mounted on said display surface; each of said first, second and third insulating layers and each of said first and second conductive layers being formed of such materials that a hole can be formed in said that layer by sticking a needle in that layer; at least one of said first and second conductive layers being divided into a plurality of separate regions of any desired shapes; each of said light-emitting devices having longer and shorter leads in pair, said pairs of leads being stuck into said multi-layered structure through said display surface substantially at any desired locations; each of said longer leads, when stuck into said multi-layered structure through said display surface, extending through said first and second insulating layers and said first conductive layer at least into said second conductive layer to contact said second conductive layer, each of said longer leads having an insulating covering on such a portion thereof as to insulate that longer lead from said first conductive layer; each of said shorter leads, when stuck into said multi-layered structure through said display surface, extending through said first conductive layer at least into said first conductive layer to contact said first conductive layer; said first conductive layer being divided into a first plurality of separate regions, said second conductive layer being divided into a second plurality of separate regions, one of regions of one of said first and second conductive layers overlapping at least two regions of the other of said first and second conductive layers.
