FLEXIBLE PRINTED CIRCUIT

摘要

PURPOSE: A flexible printed circuit is provided to insulate a metal from up and down side using a multi-layer structure in order to minimize electrostatic interference. CONSTITUTION: A flexible printed circuit includes one signal line(10), an upper and a lower dielectric layers, an upper and a lower conduction layer(30,31), and an upper and a lower preservation layers. The signal line(10) transfers electrical signal to a gate and data substrate, respectively. The upper and the lower dielectric layers are attached to the upper and the lower surfaces of the signal line(10). The upper and the lower conduction layer(30,31) are arranged on the upper and lower surfaces of each dielectric layer in order to ground the dielectric layers. The upper and the lower preservation layers are attached to the upper and the lower surfaces of the conduction layers in order to preserve the conduction layers.
