Abstract
An organic light emitting diode display device includes a substrate, a pixel structure, a first circuit transistor, a first lower electrode, a first upper electrode, and a planarization layer. The substrate has a display area and a peripheral area including a first circuit area, a second circuit area, and a blocking area positioned between the first and second circuit areas. The pixel structure is in the display area on the substrate. The first circuit transistor is in the first circuit area on the substrate. The first lower electrode is in the blocking area on the substrate. The first upper electrode is on the first lower electrode, and the first upper electrode and the first lower electrode constitute a first capacitor. The planarization layer is on the substrate, and has a first opening that overlaps the first capacitor in the blocking area.
