Abstract: An organic light emitting display device and a testing method thereof for detecting a failure occurring in a cutting process of a protective film attached to an upper end of a panel. The organic light emitting display device includes a first substrate on which a pixel unit and a tester are formed. The pixel unit includes a plurality of pixels positioned at intersection portions of scan lines and data lines, and the tester includes a plurality of transistors coupled to the respective data lines so as to supply test signals to the data lines. The transistors are divided into at least two groups, so that transistors of one group are turned on/off by a first test control line, and transistors of another group are turned on/off by a second test control line, the first and second test control lines being disposed on opposite sides of the substrate.
