ABSTRACT:
An Organic Electro Luminescence Display (OELD) to perform a sheet unit test includes a pixel unit including: a plurality of pixels to receive a first power supply voltage (ELVDD), a second power supply voltage (ELVSS) and scanning signals to emit light; a scan driving unit to supply the scanning signals to the pixel unit; and a test unit to test whether or not a defect in the pixel unit is present, and further includes a first wire group arranged in a first direction and having a floated end; and a second wire group arranged in a second direction and having a floated end. This allows the sheet unit test to be conducted without scribing each OELD, by supplying the power supply voltages and the signals for their tests into a plurality of the OELDs formed on a motherboard.
