Touch screen panel

In a method of manufacturing a display device, a first insulating layer is formed on a semiconductor pattern. Ions of a first concentration are injected into source and drain domains of the semiconductor pattern and a lower electrode of the semiconductor pattern by using a mask pattern that selectively overlaps a channel domain of the semiconductor pattern and is positioned on the top of the first insulating layer. The mask pattern is removed. An ion injection process of injecting ions of a second concentration lower than the first concentration into the semiconductor pattern of the channel domain is directly performed in the first insulating layer. A gate electrode that overlaps the channel domain is formed on the top of the first insulating layer. An upper electrode that overlaps the lower electrode is formed on the top of the first insulating layer.
