Abstract
Compressible interconnection is removably provided between a liquid crystal panel and a circuit board or a semiconductor chip to provide exchangeability for the liquid crystal panel from the viewpoint of the limited operating life inherent in liquid crystal composites. A desired number of electrodes for electrical connection are provided on both the liquid crystal panel and the circuit board to confront each other. The compressible interconnection means comprises a stack including a multiplicity of compressible and resilient conductive regions made of, for example, conductive rubber and a multiplicity of compressible, resilient non-conductive regions made of, for example, rubber in alternate fashion. The conductive regions connect the electrodes provided on the liquid crystal panel with the electrodes provided on the circuit board. The section of the conductive region is selected smaller than the distance provided between two adjacent electrodes on the liquid crystal panel and the circuit board, and the distance between two adjacent conductive regions is selected shorter than the width of the electrodes provided on the liquid crystal panel and the circuit board, thereby facilitating the installation and exchanging of the liquid crystal panel.
