Claim Text:
1. An organic light emitting diode (OLED) display comprising: a substrate; a scan line formed on the substrate and applying a scan signal; a data line and a driving voltage line intersecting the scan line and respectively applying a data signal and a driving voltage; a switching thin film transistor (TFT) connected to the scan line and the data line; a driving TFT connected to a switching drain electrode of the switching TFT and the driving voltage line; an OLED connected to the driving drain electrode of the driving TFT; a storage capacitor connected between the driving voltage line and the driving gate electrode of the driving TFT; and a boosting capacitor including a first boosting capacitor plate connected to the driving gate electrode of the driving TFT and a second boosting capacitor plate overlapping the first boosting capacitor plate and connected to the scan line, wherein the first boosting capacitor plate has a hammer shape, and the first boosting capacitor plate includes a grip parallel to the driving voltage line and a head formed at the end of the grip, wherein the second boosting capacitor plate is a protrusion protruding upward and downward from the scan line and wherein the protrusion of the second boosting capacitor plate is positioned to entirely overlap inside the head of the first boosting capacitor plate, wherein an area of the first boosting capacitor plate of the boosting capacitor is larger than an area of the second boosting capacitor plate, and wherein a first horizontal interval between a first vertical outer line of the head of the first boosting capacitor plate and a first vertical outer line of the protrusion of the second boosting capacitor plate is in a range of about 1.2 μm to about 2 μm, wherein a second horizontal interval between a second vertical outer line of the head of the first boosting capacitor plate and a second vertical outer line of the protrusion of the second boosting capacitor plate is the same as the first horizontal interval, wherein the second vertical outer line of the head of the first boosting capacitor plate is parallel and opposite to the first vertical outer line of the head of the first boosting capacitor plate, and wherein the second vertical outer line of the protrusion of the second boosting capacitor plate is parallel and opposite to the first vertical outer line of the protrusion of the second boosting capacitor plate.
