Abstract: A display device includes a substrate including a first surface, a side surface, and a second surface opposite to the first surface, a display on the first surface, an electrode pad on the second surface and electrically connected to the display, an external connection terminal on the second surface, a first wire on the second surface and electrically connecting the electrode pad and the external connection terminal, and an inspection pad on the second surface and electrically connected to the electrode pad. At least a central portion of the inspection pad does not overlap the first wire.

Abstract: A first controller included in a data recorder automatically starts transmission of data in response to contactless communication being enabled between a first communication module included in the data recorder and a second communication module included in a communication device. First control A3 includes automatically starting transmission of the data in response to contactless communication being enabled between the first communication module and the second communication module.
