Abstract:
1. A substrate of an organic light emitting display device, comprising: a plurality of organic light emitting display panels arranged in a matrix; a first wire group including a plurality of sheet wires located in peripheral regions of the panels and extending in a first direction for concurrently supplying at least one of a test power source or a test signal to the panels arranged in the first direction, and including first sheet wires for supplying a pixel power source from a first side of the substrate to the panels; and a second wire group including a plurality of sheet wires in peripheral regions of the panels and extending in a second direction crossing the first direction for concurrently supplying at least one of a test power source or a test signal to the panels arranged in the second direction, and including second sheet wires for supplying a reference power voltage from a second side of the substrate to the panels, the second sheet wires including a first wire and a second wire, the first wire being closer to the first side than the second wire, wherein voltage levels of the reference power voltage supplied to the second sheet wires at the second side vary in accordance with a position of the second sheet wires on the substrate, the first wire being supplied with a first voltage level at the second side and the second wire being supplied with a second voltage level at the second side, the first voltage level being higher than the second voltage level.
