Abstract: A display device includes a display area and a non-display area including a first driving pad portion at which a display panel is connected to an integrated circuit chip by a solder bump having a width. The first driving pad portion includes a first pad through which an electrical signal transmits between the first driving pad portion and the integrated circuit chip, and a second pad by which alignment between the first driving pad portion and the integrated circuit chip is determined. The second pad of the first driving pad portion includes a (2-1)-th pad having a width which is the same as the width of the solder bump and a (2-2)-th pad having a width which is larger than the width of the (2-1)-th pad.

Abstract: A display device includes a first substrate, first signal lines, and a first signal pad array. The first signal pads each includes a first pad portion connected to a corresponding first signal line, a second pad portion having a width larger than that of the first pad portion, and a third pad portion connecting the first pad portion with the second pad portion and having a width smaller than the width of the second pad portion. The first signal pads are disposed in a shape symmetrical with respect to an imaginary line. Each first signal pad has an angle between a direction in which the third pad portion is extended and a direction in which the second pad portion is extended. The angle of a first signal pad closer to the imaginary line is smaller than the angle of another first signal pad further away from the imaginary line.
