A structure to prevent lines of the device from being damaged or scratched by outside objects or to prevent short circuits from occurring is disclosed. The structure may be utilized in light emitting displays such as an organic electroluminescent panel. The structure includes a cell section, data lines, and scan lines. The cell section includes a plurality of pixels formed in luminescent area that are intersection areas of anode electrode layers and cathode electrode layers. The data lines each are connected to the anode electrode layers. The scan lines each are connected to cathode electrode layers. Here, insulating layers are formed to protect a subset of the data lines and/or a subset of the scan lines. Some of the lines are left uncovered so that inspection process may be carried out.
