Claim:
1. An organic light-emitting display apparatus comprising: a plurality of crossing lines including crossing pairs each crossing at least at a respective one crossing point and having an insulating layer portion interposed therebetween where a short circuit defect in the interposed insulating layer portion may occur at the respective one crossing point thereby shorting the corresponding crossing pair of lines one to the other at the respective one crossing point; a plurality of pixel units each including a respective pixel circuit that is electrically coupled to respective ones the crossing lines and each including a respective pixel light-emitting device that is coupled to and driven by the respective pixel circuit, each pixel unit being disposed to correspond to at least a respective one of the crossing points, the pixel light-emitting device comprises a pixel electrode, a pixel intermediate layer that comprises an organic emissive layer, and an opposite electrode; and a plurality of test light-emitting devices each respectively disposed to correspond to an at least respective one crossing point of a respective one of the pixel units, the respective light-emitting device being electrically coupled to a subset of the plurality of the respective crossing lines of the respective pixel unit and being configured to emit light when a short circuit is present at the respective crossing point of that test light-emitting device, the test light-emitting device comprising a lower electrode that is formed of the same material and on the same layer as the pixel electrode, and an upper electrode that is formed of the same material and on the same layer as the opposite electrode.
