ABSTRACT:
A mounted substrate is a TCP of high definition and multi-output used in connection with a liquid crystal display panel of high definition and a great number of pixels. The TCP has a base film in whose aperture an LSI chip is installed. On the back surface of the base film, input and output wiring patterns are provided. A stress-absorbing portion is provided in the neighborhood of the LSI chip on an input-terminal side to be orthogonal to the input wiring patterns. The stress-absorbing portion absorbs a stress which occurs upon connecting a PWB and the input terminal of the TCP by a heating-and-pressurizing connection method. Therefore, it is possible by utilizing the TCP to obtain a thin liquid crystal module of high definition and a great number of pixels and with a high ratio of an available display area.
