Abstract: A display device includes a display layer including an active area in which a plurality of pixels is arranged and a peripheral area located adjacent to the active area. The display layer includes a transistor disposed in the active area and including a gate, a source, and a drain, a first crack line disposed in the peripheral area and surrounding a portion of the active area in a plan view, and a second crack line disposed in the peripheral area under the first crack line. The first crack line is insulated from the second crack line.

Abstract: A display device includes: a display panel configured to display an image corresponding to an image signal, and including pads; and a driving chip configured to provide data signals to the pads. The driving chip includes: an analog part configured to convert an input voltage received through an input line into a driving voltage, and convert an image data signal into the data signals; and buffers configured to receive a buffer voltage through a buffer line that is different from the input line, and output the data signals to the pads.

Abstract: Disclosed is a method of manufacturing a display device, the method including manufacturing an electronic component and attaching the electronic component to a display panel using a conductive adhesive member. The manufacturing of the electronic component includes providing a substrate and a conductive layer disposed on the substrate, a primary etching of the conductive layer to form a preliminary bump electrode, and a secondary etching of the preliminary bump electrode to form a bump electrode.
