Organic electroluminescent display device, substrate of the same and method of cutting the substrate

A substrate of an organic EL device, comprising:

• a single transparent base panel;
• organic light emitting portions formed on the base panel at a predetermined interval;
• encapsulation caps which encapsulate the respective organic light emitting portions;
• and
• first groups and second groups of electrodes which drive the respective organic light emitting portions, wherein each pair of first group and second group of electrodes includes:
• first and second electrode terminals, respectively, which are drawn out from one or more edges of a corresponding one of the encapsulation caps, and
• first and second dummy electrodes, respectively, which extend from the first and second electrode terminals to a dead space between the corresponding encapsulation cap and one or more adjacent encapsulation caps, wherein ends of the first and second dummy electrodes are patterned to be connected to one or more adjacent organic light emitting portions so as to inspect the substrate in terms of a unit substrate whether the first and second electrode terminal s are short-circuited or disconnected.

• fixing encapsulation caps to encapsulate the organic light emitting portions onto the base panel, and
• patterning first and second groups of electrodes including first and second electrode terminals drawn out from one or more edges of each of the encapsulation caps to drive the organic light emitting portions, and first and second dummy electrodes extending from the first and second electrode terminals into dead space areas between the encapsulation caps and adjacent encapsulation caps;
• and
• cutting a portion between each of the encapsulation caps so as to partition the organic EL devices into a plurality of unit organic EL devices.

A substrate of an organic EL device comprising:

• a single base panel;
• organic EL devices formed on the base panel at a predetermined interval so as to be partitioned into two or more areas;
• and
• first groups and second groups of electrodes which drive the respective organic EL devices and include first and second electrode terminals which are drawn out from the respective organic EL devices in a matrix type so as to sequentially and electrically connect the first group and second group of electrodes provided at each of the organic EL devices in each area to first groups and second groups of electrodes of adjacent organic EL devices, thereby allowing an inspection by the first and second groups of electrodes of the outermost organic EL devices in each area whether the first and second groups of electrodes are short-circuited or disconnected.
