A display device and a method for manufacturing a display device are provided. An embodiment of a display device includes a display panel including a pad area including a plurality of pads, a first circuit board disposed to partially overlap the pad area; wherein the first circuit board includes: a first base board; a conductive layer disposed on the first base board and including a plurality of first bumps disposed on one end portion of the first base board, a plurality of second bumps disposed on the opposite end portion of the first base board, and a lead wiring connecting the first bump to the second bump, a passivation layer disposed on the first base board to cover the lead wiring; an adhesive layer disposed on the passivation layer to at least partially cover a top and side surface of one end portion of the display panel.

Display device and method for manufacturing the same

A display device includes a display substrate comprising a plurality of pixels electrically connected to select lines and data lines; first connection pads disposed on an upper surface of the display substrate and electrically connected to the pixels; and second connection pads disposed on a surface of the display substrate that is different from the upper surface and electrically connected to the pixels, wherein the second connection pads are electrically separated from the first connection pads. This allows the area of a surface of a display substrate that can be occupied by a flexible printed circuit board attached thereto to be increased. As a result, the risk of an open-circuit of the wiring can be reduced, and the operational reliability of the device can be improved.
