Display device and method for manufacturing the same

A display device comprising:

• a first substrate comprising a top surface, a bottom surface, and a plurality of side surfaces connecting the top surface and the bottom surface;
• a second substrate facing the top surface of the first substrate;
• a signal line disposed on the top surface;
• a sidewall electrode disposed on a side surface of the second substrate which is aligned with a first side surface of the side surfaces of the first substrate;
• a sealing member disposed between the first substrate and the second substrate and electrically connecting the sidewall electrode to the signal line;
• a circuit board comprising a driving pad and facing the first side surface and the side surface of the second substrate;
• a connection electrode in electrical contact with the sidewall electrode and disposed on the first side surface and the side surface of the second substrate;
• and
• an adhesive member electrically adhering the driving pad to the connection electrode.

A method for manufacturing a display device, the method comprising:

• forming a first portion of a pad electrode on a top surface of a substrate, the pad electrode comprising the first portion extending in one direction;
• and a second portion extending from the first portion;
• forming the second portion on a side surface of the substrate by grinding the second portion using a grinder;
• forming a connection electrode on the side surface of the substrate such that the connection electrode is in electrical contact with the second portion;
• and
• electrically connecting the connection electrode to a driving pad of a circuit board facing the side surface of the substrate by using a conductive adhesive member.
