Abstract:
1. An organic light emitting display panel comprising: a display unit at crossing regions of scan lines and data lines, the display unit comprising a plurality of pixels configured to display different colors, the pixels being arranged in a pattern; a test circuit at a first side of the panel, the first side being opposite to a side of the panel having a data driver, the test circuit being coupled to one end of the data lines and to a plurality of test signal lines; and an auxiliary line adjacent to the plurality of test signal lines and coupled to at least one of the plurality of test signal lines, wherein the auxiliary line comprises: a first auxiliary line that extends along the test signal lines at a second side of the panel, the second side being a left side of the panel, and is coupled to one of the test signal lines at a central part of the first side of the panel, at a non-display portion; and a second auxiliary line that extends along the test signal lines at a third side of the panel, the third side being a right side of the panel, and is coupled to another one of the test signal lines at a central part of the first side of the panel, at a non-display portion, wherein a first test signal for light emission of first pixels and a second test signal for light emission of second pixels are alternately provided to one data line coupled to a pixel column, wherein the first pixels for displaying a first color and the second pixels for displaying a second color are alternately arranged, wherein the first auxiliary line is directly coupled to a first test signal line for supplying the first test signal from among the test signal lines, and wherein the second auxiliary line is directly coupled to a second test signal line for supplying the second test signal, from among the test signal lines.
