Liquid crystal display device

Abstract

A display device includes a first conductive layer formed on a substrate, an insulating layer formed on a portion of the first conductive layer and having a flat plane and an edge, and a second conductive layer continuously formed on the flat plane of the insulating layer, on the edge of the insulating layer, and on another portion of the first conductive layer.
