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.

Abstract: A display device may includes: a substrate including a pixel area and a peripheral area; pixels provided in the pixel area of the substrate, each of the pixels including a light-emitting element provided with a pixel electrode; scan lines and data lines coupled to the pixels; a power line configured to supply driving power to the light-emitting elements, and extending in one direction; and an initialization power line configured to supply initialization power to the light-emitting elements. The power line and the initialization power line may be provided on different layers. The initialization power line may include: first conductive lines extending in a direction oblique to the scan lines and the data lines; and conductive lines intersecting the first conductive lines. The first and second conductive lines may be disposed in areas between the pixel electrodes of adjacent light-emitting elements.
