Display device and inter-substrate conducting structure

A display device comprising:

• a first substrate comprising a first basement and a first conductive layer, the first basement including a first end surface;
• a second substrate comprising a second basement and a second conductive layer and opposed to the first substrate, the second basement including a second end surface;
• and
• a display function layer located between the first substrate and the second substrate,
• wherein
• the second end surface includes a flat portion located in a same plane as the first end surface, and a first concave portion formed toward an inside of the second basement with respect to the flat portion, and
• a connecting material which electrically connects the first conductive layer and the second conductive layer is provided in the first concave portion.
