Abstract
A flat panel display having an integrated touch screen panel directly formed on a sealing thin film is disclosed. In the display, sensing lines of the touch screen panel are formed to extend to a substrate of the display panel, on which organic light emitting elements are formed, so that the touch screen panel and the display panel are connected to a flexible printed circuit board, thereby simplifying manufacturing processes and decreasing product cost.
