Display device and electronic device including the same

An electronic device comprising:

• a housing;
• and
• a display device mounted in the housing,
• wherein the display device comprises:
• a display panel which includes a non-bonding area formed at an end portion thereof and defining a first side portion and a second side portion of the end portion the display panel;
• a first substrate which has a first end portion connected with the end portion of the display panel and a notch formed therein to correspond to the non-bonding area, and includes a driving element configured to control driving of the display panel;
• and
• a second substrate connected with a second end portion of the first substrate,
• wherein the display panel comprises a first-1 test pad disposed at the first side portion of the display panel and a first-2 test pad disposed at the second side portion of the display panel,
• the first substrate comprises a first-1 connection pad bonded with the first-1 test pad, a first-2 connection pad bonded with the first-2 test pad, a second-1 connection pad connected with the first-1 connection pad through a first line, and a second-2 connection pad connected with the first-2 connection pad through a second line,
• the second substrate comprises a second-1 test pad bonded with the second-1 connection pad, a second-2 test pad bonded with the second-2 connection pad, a first test point connected with the second-1 test pad, and a second test point connected with the second-2 test pad, and
• a portion of the first line and a portion of the second line are overlapped with the driving element.
