    • A one sheet test device and a method of testing using the same that can prevent a change of current characteristics due to a failure panel by measuring a current of normal panels except for the failure panel, when testing a one sheet substrate that includes panels, first wires that are arranged in a first direction between and connected to the panels, second wires that are arranged in a second direction different from the first direction between and connected to the panels. The test device includes voltage application units that are connected to the first and second wires, respectively, to apply a selected one of the first voltage and the second voltage to the corresponding wires; and a test unit that controls the voltage application units to measure an on-current and off-current of each of the panels.
