Thin film transistor array panel and manufacturing method thereof

摘要

The present invention relates to a thin film transistor array panel and a manufacturing method thereof, and a thin film transistor array panel according to an exemplary embodiment of the present invention includes: a substrate; a first conductive layer disposed on the substrate; a second conductive layer overlapping at least a portion of the edge of the first conductive layer on the first conductive layer and including a first portion overlapping the first conductive layer and a second portion not overlapping the first conductive layer; a first insulating layer disposed on the second conductive layer and having a contact hole exposing at least a portion of a boundary between the first portion and the second portion; and a third conductive layer disposed on the first insulating layer and simultaneously contacting the first portion and the second portion that are exposed through the contact hole.
