Circuit board connection structure and method, and liquid crystal device including the connection structure

摘要

A circuit board connection structure is formed by a first substrate having a first electrode pattern, a second substrate having a second electrode pattern, and a film circuit member electrically connecting the first and second electrode patterns. The film circuit member includes lead electrodes having an exposed portion partly connected to the first electrode pattern at a part of the exposed portion closer to an edge of the film circuit member. The film circuit member may further includes lead electrodes having an exposed portion partly connected to the second electrode pattern at a part of the exposed portion closer to an edge of the film circuit member. The circuit board connection structure may be incorporated in various electronic devices, including a liquid crystal display device.
