Abstract

The invention provides a display device. The display device includes: a substrate including a display area and a pad area; a pixel structure disposed in the display area on the substrate; a pixel insulating layer disposed on the pad region on the substrate and having a first opening; and a pad electrode structure including a signal electrode disposed on the first opening on the substrate, a connection electrode disposed on the signal electrode, and a pad electrode disposed on the connection electrode, in which an upper surface and a side surface of the signal electrode are in direct contact with a bottom surface of the connection electrode, the upper surface and the side surface of the connection electrode are in direct contact with the bottom surface of the pad electrode.

Description

technical field [0001] The present invention relates to a display device. In more detail, the present invention relates to a display device including a pad region. Background technique [0002] Display devices used for computer displays or TVs, cellular phones, and the like include organic light emitting display devices (OLED: organic light emitting display), etc., which emit light, and liquid crystal display devices (LCD: liquid crystal display), which require a separate light source, and the like. [0003] In addition, a pad electrode structure electrically connected to an external device may be arranged in the pad area of ​​the display device. For example, the pad electrode structure may have a structure in which metal layers are stacked. Also, in order to prevent the corrosion phenomenon that may occur on the side surfaces of each of the metal layers, the side surfaces of each of the metal layers may be covered with an organic insulating layer or an inorganic insulatin...
