Abstract
Abstract There is provided a highly reliable panel assembly structure capable of performing fine-pitch high-density assembling at a high yield and a low cost. A flexible wiring board has a film-like substrate with flexibility, and an IC chip is mounted in an area. In the area is provided a through hole that has plane dimensions smaller than plane dimensions of the chip and penetrates the substrate. Portions that belong respectively to an output side wiring line and an input side wiring line provided on a substrate surface and are connected respectively to an output side electrode and an input side electrode of the chip via second connection materials and are supported by the substrate surface. An output terminal of the flexible wiring board is connected to an electrode terminal formed at a peripheral portion of a panel via a first connection material, while an input terminal of the flexible wiring board is connected to an electrode terminal of a circuit board via a third connection material.
