Abstract

Provided is a liquid crystal module with which the additional miniaturization of liquid crystal display devices is possible. The liquid crystal module is composed of at least the two liquid crystal display devices 1 and 2 constituted to be separated from each other, a first flexible substrate 3a mounted with a semiconductor chip for driving the liquid crystal display devices 1 and 2 and a second flexible substrate 7a formed with wiring for signal connection. The one liquid crystal display device 1 and the first flexible substrate 3a are electrically connected and the other liquid crystal display device 2 and the second flexible substrate 7a are electrically connected. The first flexible substrate 3a and the second flexible substrate 7a are electrically connected.

Description

technical field [0001] The present invention relates to a structure of a flexible substrate (also referred to as a tape carrier) on which semiconductor chips and passive components for driving a liquid crystal display device are mounted, and a liquid crystal module including the liquid crystal display device. Background technique [0002] With the rapid spread of today's cellular phones, high added value has been generated and rapid progress has been made in their functions. Remarkable progress has been made not only in software such as animation playback functions and network connection functions, but also in hardware functions such as photography functions. Among them, not only the main liquid crystal display device when the conventional telephone function and network function are mainly used, but also the sub liquid crystal used for auxiliary purposes such as mail and telephone incoming call display, communication status display, battery remaining display, etc. Mobile ph...
