MISALIGNMENT DETECTION METHOD, MISALIGNMENT DETECTION DEVICE, AND DISPLAY DEVICE

摘要

To precisely detect, by a simple method, misalignment between an electrical connection of a semiconductor element and an electrical connection of a device that is electrically connected to an electrical connection of the semiconductor element.SOLUTION: Misalignment between an electrode pad 2 and an electrode 5 is detected based on a conduction state between the electrode pad 2 of a semiconductor element and the electrode 5 of a device. The electrode pad 2 is divided into a plurality of portions, and includes a first pad 21 to a fourth pad 24 which are uniformly arranged. A misalignment detection section determines that there is no misalignment when the electrode pad 2 is conducted to the electrode 5, and determines that there is misalignment when the electrode pad 2 is not conducted to the electrode 5.SELECTED DRAWING: Figure 1
