Flat type display device and driving method and assembling method therefore

摘要

A display device has a display panel board (222) and a drive LSI (220) for driving the display panel board (222). The drive LSI (220) is mounted on a flexible board (219,233). The output line from each output terminal (221) of the drive LSI (220) is ramified, and is connected to at least two scanning lines of the display panel board (222). A switch (212a, 212b......)is placed in each scanning line, after the point at which the output line from the drive LSI (220) ramifies.
