Organic light emitting display and mother substrate thereof

摘要

A substrate of a plurality of organic light emitting displays. The substrate includes a first wiring line group extending in a first direction to be coupled to organic light emitting displays in a same column among the plurality of organic light emitting displays, and a second wiring line group extending in a second direction to be coupled to organic light emitting displays in the same row among the plurality of organic light emitting displays. The first and second wiring line groups are arranged on the substrate to allow testing of the plurality of organic light emitting displays as a unit sheet.
