Abstract: A display device includes: a display panel having a display region in which a pixel is disposed and a non-display region in which a pad electrode is disposed; a driving part disposed on the display panel and having a bump electrode disposed to correspond to the pad electrode; and an adhesive layer in contact with the pad electrode and the bump electrode. The pad electrode includes: a first connection pattern containing a conductive material; an auxiliary pattern disposed on the first connection pattern, protruding toward the bump electrode, and containing an insulating material; and a second connection pattern, which contains a conductive material, of which a portion is disposed on the auxiliary pattern, and in which an opening that exposes a portion of the auxiliary pattern is defined, and the auxiliary pattern includes a tip portion more protruding toward the opening than the first connection pattern.

Abstract: A display device includes a pixel, a signal line electrically connected to the pixel, and a signal pad connected to the signal line. The signal pad includes a first conductive pattern disposed on the pad part, a second conductive pattern disposed on the first conductive pattern, and an insulating pattern, which, in a cross-section, is disposed between the pad part of the signal line and the second conductive pattern, and in a plan view, overlaps the second conductive pattern. The insulating pattern passes through the first conductive pattern via an upper reinforcement hole defined in the first conductive pattern.
