Display device and electronic device including the same

A display device comprising:

• a display panel comprising a display region in which pixels are disposed and a non-display region in which a plurality of pad electrodes are disposed;
• and
• a driving unit disposed on the display panel and comprising a plurality of bump electrodes, each of the plurality of bump electrodes connecting to a corresponding pad electrode among the plurality of pad electrodes,
• wherein the plurality of bump electrodes comprise:
• a plurality of first bump electrodes arranged along a first direction;
• and
• a plurality of second bump electrodes arranged along the first direction,
• wherein the plurality of first bump electrodes are spaced apart from the display region with the plurality of second bump electrodes interposed between the plurality of first bump electrodes and the display region,
• wherein each of the plurality of first bump electrodes and the plurality of second bump electrodes comprises:
• a plurality of protruding members protruding to be adjacent to the display panel;
• and
• a bonding layer covering the plurality of protruding members, the bonding layer of each of the plurality of first bump electrodes partially in contact with a first pad electrode among the plurality of pad electrodes and the bonding layer of each of the plurality of second bump electrodes partially in contact with a second pad electrode among the plurality of pad electrodes,
• wherein a first area of each of the plurality of first bump electrodes is different from a second area of each of the plurality of second bump electrodes, and
• wherein a first contact area between the bonding layer of each of the plurality of first bump electrodes and the first pad electrode is different from a second contact area between the bonding layer of each of the plurality of second bump electrodes and the second pad electrode.
