[ 20. An organic light-emitting diode (OLED) display, comprising:
a plurality of pixels, wherein each of the pixels are connected to a corresponding data line of a plurality of data lines and a corresponding scan line of a plurality of scan lines,
wherein each of the pixels includes:
a storage capacitor configured to store a data voltage;
a compensation transistor having one end electrically connected to a current path of the storage capacitor;
an organic light emitting layer;
a first electrode of an OLED formed below the organic light emitting layer; and
a driving transistor configured to adjust an amount of current flowing in the OLED, and
wherein an electrode extension of the first electrode blocks at least a portion of the compensation transistor from light to prevent an occurrence of a light leakage current on a current leakage path of the storage capacitor,
wherein the compensation transistor has a first end electrically connected to a gate electrode of the driving transistor and a first end of the storage capacitor, and a second end electrically connected to a first end of the driving transistor, wherein the electrode extension of the first electrode of a first one of the pixels overlaps the compensation transistor of a second other one of the pixels adjacent the first pixel, and
wherein no portion of the compensation transistor overlaps the organic light emitting layer of the OLED display.]
