ABSTRACT:
The present invention relates to an identification mark portion and fabricating method thereof, more particularly, to an identification mark portion introduced in a liquid crystal display panel and a fabricating method thereof, which minimizes the error in verifying an ID of a pad by preventing at least two insulating layers from overlapping each other over the upper part of the pad. The present invention includes an insulating substrate, an ID mark pad including an ID mark on the insulating substrate, and a first insulating layer and a second insulating layer on the insulating substrate wherein the first and second insulating layers expose the ID mark in the ID mark pad. In another aspect, the present invention includes the steps of forming an ID mark pad including an ID mark on an insulating substrate, and forming a first and a second insulating layer which expose the ID mark in the ID mark pad.
