A wiring method for checking wirings of an organic electroluminescent display, in which a plurality of organic electroluminescent displays are arranged and encapsulated on a large piece of glass substrate, a power contact block with a main checking wiring is arranged at one side of the glass substrate, the cathode and the anode of the display which is at the centre are connected to said main checking wirings through an electrically conductive cathode checking wiring and an electrically conductive anode checking wiring, respectively. The main checking wirings connect the plurality of displays to the power contact block in series or parallel at a side of the glass substrate, wherein said cathode checking wiring may be connected to the cathode from any side of the display, then be wired and extended out, said anode checking wiring may be wired and extended out from other one side other than the anode end side which is connected to the integrate circuit for the display, and the anode checking wiring is only is connected to other end of the anode.
