Abstract
The present invention relates to an organic light emitting diode display capable of suppressing voltage distribution inhomogeneity on a display panel so as to realize a brightness homogeneity of a display screen. The organic light emitting diode display comprises a substrate, an active region disposed on the substrate, and an annular wiring similarly formed on the substrate and surrounding the periphery of the active region to form a closed pattern, the supply voltage supplied to the active region is applied to the annular wiring.
