Method of manufacturing semiconductor device

摘要

In the steps of manufacturing a liquid crystal display, a step of reducing the electrostatic destruction of switching elements is provided. An electrostatic destruction preventing short-circuiting ring is left on an active matrix substrate until the execution of a short-circuiting bar-carrying FPC fixing step is finished. This enables the electrostatic destruction of the switching elements, which occurs due to the operations in a chamfering step to a FPC fixing step, to be reduced.
