Display device

A display device comprising:

• a display section including a first substrate and a second substrate, the display section displaying an image according to an electric signal;
• a terminal pad that electrically connects a conductor provided on the first substrate or the second substrate to a signal source that supplies the electric signal or to a ground node;
• and
• an information code expressing information in an optically readable form, wherein
• the second substrate has a substrate overlapping area and a substrate non-overlapping area, the substrate overlapping area overlaps the first substrate in a plan view and the substrate non-overlapping area does not overlap the first substrate such that one side edge of the second substrate extends out from one side edge of the first substrate,
• at least a part of the terminal pad serves as a light-transmitting portion configured to transmit light, and
• the terminal pad and the information code are disposed in the substrate non-overlapping area on one plate surface of the second substrate, the one plate surface facing the first substrate, such that the terminal pad and the information code overlap each other in a plan view and the light-transmitting portion covers an upper surface of the information code.
