Abstract: In an LED lamp, a copper film is first formed on a substrate by plating. A resist is then bonded onto the copper film so that shaped like a ring viewed from the whole of the LED lamp. A nickel and a gold film are formed on a portion of the copper film where the resist is not bonded. Next, an adhesive agent is applied onto a bottom of the lamp house so that the lamp house is bonded onto the substrate through the adhesive agent. A transparent epoxy resin is packed in the frame of the lamp house and hardened by heating to perform resin sealing. Since the resist is bonded onto the surface of copper having a large number of fine irregularities sufficient to ensure a large contact area and excellent in adhesion, separation can be prevented from being caused by thermal stress.

Abstract: On a first substrate provided on a display surface of a plasma display panel, bus electrodes (12a, 14a) in X and Y electrode lines (12, 14) forming a pair of display electrode lines are formed with an Ag material containing a black additive (RuO2, etc.) by a screen printing. This prevents external light from being reflected at the surfaces of the bus electrodes (12a, 14a) on the display side of an FP substrate (10) to improve the display contrast. The bus electrodes (12a, 14a) may be formed as a multi-layer structure. In this case, for example, the lower-layer bus electrodes are formed with a black metal material and the upper-layer bus electrodes are formed with a light-reflecting material layer, which improves light utilization efficiency and further improves the contrast.
