1. An organic light emitting display device comprising:

  • a plurality of data lines positioned in one direction;

    a plurality of gate lines positioned in another direction intersecting with the plurality of data lines;

    a plurality of pixels connected with the plurality of data lines and the plurality of gate lines; and

    a reference voltage line positioned in the one direction and configured to supply a reference voltage to the pixels,wherein each of the plurality of pixels includes;

    an organic light emitting diode, a driving transistor configured to drive the organic light emitting diode, a first transistor controlled by a first scan signal from the gate lines and connected between the reference voltage line and a first node of the driving transistor, and a second transistor controlled by a second scan signal supplied from the gate lines and connected between the data lines and a second node of the driving transistor,wherein each first transistor has a first source/drain node and a second source/drain node, wherein the first source/drain nodes of the first transistors of two or more pixels are configured as a shared node formed integrally with the reference voltage line, and the second source/drain nodes of the first transistors of said two or more pixels are configured as respective nodes separate from each other, and each of said respective nodes is connected with the first node of the driving transistor of a respective pixel directly or through a connection pattern.
