    Abstract: A driving chip includes a body portion including a circuit. A first bump is electrically connected to the body portion. A second bump is disposed on the first bump. The second bump has a planar area less than a planar area of the first bump on a plane defined along a first direction parallel to an upper surface of the body portion. The first bump has a length of about 60 μm or more in the first direction, a side surface of the second bump is aligned with a side surface of the first bump along a second direction orthogonal to the first direction.

    Abstract: A display device includes: a display panel including a display region and a non-display region; a window member on the display panel; and an adhesive member between the display panel and the window member. The adhesive member includes: a first adhesion portion overlapping the display region, and a second adhesion portion extending from the first adhesion portion and overlapping the non-display region. The display panel includes: a substrate, a display element layer on the substrate and overlapping the display region, a driving chip on the substrate and overlapping the non-display region, and an encapsulation member on the display element layer. The driving chip is configured to provide a driving signal to the display element layer. The first adhesion portion connects the window member to the encapsulation member. The second adhesion portion connects the window member to the substrate and encloses the driving chip, but does not overlap the driving chip.
