发明名称 Noise-shield sheet and liquid crystal display device using the same
摘要 There are provided a noise-shield sheet which can easily add a shield layer without complicating the wiring on a circuit board and which can prevent a short-circuiting between the shield layer and the electronic part's lead and connection terminals, and a liquid crystal display device using such a noise-shield sheet. The noise-shield sheet has holes each of which permits an electric component protruding from the surface of the circuit board to be passed through the hole and is mounted on the circuit board to avoid noise. The noise-shield sheet is made up of an insulating base layer and a shield layer of electrically conductive material formed on the insulating layer. Each of the holes has a first hole formed by etching the shield layer and a second hole formed by the insulating layer within the first hole at a position separate from the edge of the shield layer.
