Problems solved by technology

[0010] exist Figure 5 , in the liquid crystal display device of the conventional structure shown in FIG. In terms of narrow borders, it is a structure with poor configuration efficiency
[0011] Additionally, even with Figure 7 In the structure shown, when the ACF films 111, 112 are pasted on the substrate 102, an intersection of about ±0.3 mm will inevitably occur. The area with a minimum width of about 0.6 mm is also a useless area that cannot be ignored for miniaturized electronic devices such as mobile phones.

Abstract

The invention relates the wiring connecting structure and liquid crystal display device. Crossing the element connecting area and FPC wiring area there is ACF film composed by conducting particles in resin binder, the connecting terminal and elements on ACF film are connected with the wiring, and FPC film is connected with the FPC by wiring. The invention makes the wiring structure simple and common, and improves the dependability of connection.

Description

technical field [0001] The present invention relates to a connection structure suitable for a wiring portion of a liquid crystal display device, etc., and particularly relates to a technology capable of connecting elements such as a driver IC card mounted on a substrate and a flexible printed circuit board without gaps. Background technique [0002] A liquid crystal display device is generally composed of a liquid crystal panel in which liquid crystal is sealed between upper and lower lens substrates, its drive circuit, and a circuit board electrically connected to an image signal processing device. The driving circuit is configured by mounting a driving IC, power supply components, etc. on a film substrate on which a predetermined wiring pattern is formed, and is generally configured as a flexible connection substrate that connects a liquid crystal panel and a circuit substrate. [0003] As the connection method between the flexible connection board and the circuit board, i...
