Abstract
A display device includes: a substrate including a pad area; a plurality of first conductive pads disposed in a matrix form in the pad area in a first direction and in a second direction intersecting the first direction; protrusions disposed on the plurality of first conductive pads; and a plurality of second conductive pads disposed on the plurality of first conductive pads and the protrusions. The plurality of second conductive pads include: contact portions in contact with the first conductive pads; and raised portions configured to extend from the contact portions, to cover the protrusions, and to have heights greater than that of the contact portions. The plurality of second conductive pads include an ultrasonic bondable material.
