摘要： A mother substrate including a plurality of organic light emitting display panels that include pixel circuits having a simple structure, is designed so that a sheet unit test may be performed while preventing or reducing brightness variation during sheet unit test, and a sheet unit test method for the mother substrate. The mother substrate also includes first and second wiring line groups and a compensating unit. The compensating unit is coupled to a coupling line for coupling a wiring line from among the first and second wiring line groups for transmitting a sheet unit test signal to the panels. The compensating unit is also for subtracting a voltage corresponding to a threshold voltage of a driving transistor included in a pixel of the panels from the sheet unit test signal before transmitting the sheet unit test signal to the panels.
