Abstract

An organic light emitting diode display panel includes data lines arranged in a first direction; gate lines arranged in a second direction to cross the data lines; a driving voltage line arranged in the first direction; a reference voltage line arranged in the first direction; data pads respectively at ends of corresponding ones of the data lines; a driving voltage pad at an end of the driving voltage line; and a reference voltage pad at an end of the reference voltage line. A first distance is defined between the driving voltage pad and an adjacent data pad, a second distance is defined between adjacent ones of the data pads, and a third distance is defined between the reference voltage pad and an adjacent data pad. At least two of the first distance, the second distance, and the third distance are different from each other.
