Patent ID: 7285727

Claim:
An electric component assembly, comprising: a liquid crystal panel having at least one patterned electrode on one side of a substrate, a flexible wiring board for double-side connection bonded to the liquid crystal panel with anisotropic conductive adhesive, the flexible wiring board comprising: a film-shaped insulating substrate comprising a through-hole at a given location; and a first and second electrode, wherein the first and second electrodes are provided at the through-hole closed by at least one of the first and second electrodes on opposite sides of the film-shaped insulating substrate from each other and are electrically connected to one another, the first electrode is made of a plating layer formed on a copper foil layer, and the patterned electrode of the liquid crystal panel is in a straddling position over the opening of the through-hole of the flexible wiring board for double-side connection and connected electrically to the plating layer of the first electrode by conductive particles of the anisotropic conductive adhesive in such a manner that prevents the anisotropic conductive adhesive from flowing through the patterned electrode; and a circuit board mounting an electric component, wherein the circuit board is bonded to the flexible wiring board with the anisotropic conductive adhesive and an electrode of the circuit board is electrically connected to the second electrode of the flexible wiring board by the conductive particles of the anisotropic conductive adhesive.
