The apparatus for fabricating an organic electroluminescent device which can distribute stress applied to the mask uniformly to form precise and reliable light emitting layers is disclosed. The apparatus for fabricating an electroluminescent device according to the present invention comprises a plurality of grippers disposed in a zigzag state at a periphery of a mask for clamping the mask, a plurality of jaws formed on each gripper and contacting with the mask, and power supplying units for supplying power to the grippers to stretch the mask. Each of the grippers is divided into a connecting section connected to the power supplying unit and a head section integrated into the connecting section, and a plurality of jaws are formed on the head section of each gripper, and odd (or even)-numbered grippers disposed at each side of the mask are disposed in a more forward position than even (or odd)-numbered grippers. Accordingly, the head section of each even (or odd)-numbered gripper is placed between the connection sections of two adjacent odd (or even)-numbered grippers. The head sections of even-numbered grippers and the head sections of odd-numbered grippers are arranged alternatively in two different imaginary lines. Also, the jaws are arranged in a line on the head section of each gripper or are arranged in a zigzag state on the head section of each gripper. At this time, the jaws are arranged by equal distance from each other.
