ABSTRACT:
The present invention reduces a connection failure between two conductive layers which are connected with each other via a through hole in a display device and reduces a defect of an orientation film formed on a TFT substrate side in a liquid crystal display device. A display device includes a display panel in which a first conductive layer formed on a surface of a substrate, and a second conductive layer which is formed over the first conductive layer as viewed from a surface of the substrate by way of a thin film layer formed of one insulation film or two or more stacked thin films including one insulation film are electrically connected with each other in an opening portion formed in the thin film layer. Out of opening ends of the opening portion of the thin film layer, an outer periphery of the opening end remote from the surface of the substrate changes a distance from the surface of the substrate one time or more during one turn of the outer periphery.
