PURPOSE:To test accurately and easily a display element wherein electrode terminals are packaged to extremely high density by drawing out the electrode terminals periodically and connecting test terminals thereto. CONSTITUTION:A substrate where electrode terminals 4a of liquid-crystal display elements 4 are formed are drawn out, and test terminals 4'a are provided to the substrate drawn parts 4'. The terminals 4'a are different in length periodically. Rubber connectors 5a-5c are connected to the test terminals a1,a2...an-c1,c2... cn. A test signal is supplied to the connector 5a firstly to turn on only the element connected thereto. Then, the test signal is sent to the connectors 5a and 5b and the elements are turned on similarly to make a check. Further, the test signal is supplied to the connectors 5b and 5c to make a decision. Thus, the test is taken, and then the substrate drawn parts 4' are separated from the liquid- crystal display elements. |
