摘要

PROBLEM TO BE SOLVED: To provide an electrophoresis display device or the like capable of directly measuring a resistance value of a contact resistance of a common electrode. A method of measuring a contact resistance value of the common electrode in an electronic device having a common electrode, wherein a first substrate provided with the common electrode, a pixel electrode and a plurality of terminals are provided, and two different conductors are provided. The unit provides an electrical display device comprising a second substrate that electrically connects two of the plurality of terminals to different points of the common electrode, and provides a power supply and a current meter. A method of measuring the current between the two terminals. [Selection diagram] FIG. 7
