Abstract: A display device includes a substrate that includes a display area and a non-display area, a display element layer disposed on the display area of the substrate, an opposing substrate that faces the substrate and the display element layer, a sealing member disposed on the non-display area and that couples the substrate and the opposing substrate, and a filler disposed between the substrate and the opposing substrate. A thickness of the filler varies in the range of 60% to 400% of a thickness of the sealing member.

Abstract: A structure is provided by a welding method of connecting a connection terminal piece to lead wires extending from a deflection yoke coil for deflecting electron beams. The lead wires are led out from a winding body and consist of one or more conductive cores each of which has a coating layer of a self fusing layer and a high thermal-resistance insulation layer therearound. The welding method includes the steps of burning and eliminating said self fusing layer and said high thermal-resistance insulation layer of said lead wires from said conductive cores by heating through a burning method, and fusing and solidifying a filler metal wherein said filler metal is disposed between said connection terminal piece and said lead wires and has conductive and adhesive properties. The burnt materials of said self fusing layer and said high thermal-resistance insulation layer are extracted out of said lead wires during said burning and eliminating step.
