Organic light emitting display apparatus and method of inspecting patterns of the organic light emitting display apparatus

An organic light emitting display apparatus comprising:

• a substrate comprising a major surface, wherein a display area and a non-display area are defined over the major surface;
• an array of pixels formed in the display area, each pixel comprising a first electrode and an organic emissive layer, the first electrode being made of a first conductive material;
• a second electrode disposed over the array of pixels;
• and
• a plurality of discrete patterns formed in the non-display area, each discrete pattern comprising a first conductive layer and a second conductive layer formed over the first conductive layer, the first conductive layer made of the first conductive material, each discrete pattern comprising an extension elongated in a direction between two end points that do not further extend into the display area,
• the apparatus further comprising two electrically conductive pads,
• wherein the plurality of discrete patterns are disposed between the two electrically conductive pads, and wherein two of the discrete patterns adjacent to the electrically conductive pads are electrically connected to the electrically conductive pads, respectively.
