Method of mounting flexible circuit boards, and display device

Abstract

The present invention is a method of mounting flexible circuit boards including: electrode groups formed on an insulating substrate; terminal groups formed in the vicinity of at least one side of the insulating substrate in such a manner as to be connected to outside at the electrode ends of the electrode groups; and terminals to be connected to the terminal groups; and a plurality of flexible circuit boards equipped with driver circuits for inputting signals to the electrode groups via the terminals, wherein the method includes the step of mounting the flexible circuit boards on the insulating substrate in a manner that the flexible circuit boards share overlap regions with adjacent flexible circuit boards.

1 . Method of mounting flexible circuit boards including: electrode groups formed on an insulating substrate; terminal groups formed in the vicinity of at least one side of the insulating substrate in such a manner as to be connected to outside at the electrode ends of the electrode groups; and terminals to be connected to the terminal groups; and a plurality of flexible circuit boards equipped with driver circuits inputting signals to the electrode groups via the terminals, wherein said method includes the step of mounting the flexible circuit boards on the insulating substrate in such a manner that the flexible circuit boards share overlap regions and have physical contacts in said overlap regions with adjacent flexible circuit boards.
