Abstract
A display device includes a substrate having a first side surface adjacent to an upper surface, a second side surface adjacent to a lower surface, and an opening surrounded by the second side surface, a pad clad surrounded by the first side surface of the substrate and including a pad contact hole, a pad disposed on the pad clad and inserted into the pad contact hole, a fan-out line disposed on the pad and electrically connected to the pad, a transistor electrically connected to the fan-out line, and a flexible film disposed under the substrate and including a lead electrode inserted into the opening of the substrate and in contact with the pad.
Claims20
A display device comprising:
- a substrate which includes a first side surface adjacent to an upper surface and a second side surface adjacent to a lower surface, and in which an opening surrounded by the second side surface is defined;
- a pad clad surrounded by the first side surface of the substrate and including a pad contact hole;
- a pad disposed on the pad clad and inserted into the pad contact hole;
- a fan-out line disposed on the pad and electrically connected to the pad;
- a transistor electrically connected to the fan-out line;
- and
- a flexible film disposed under the substrate and including a lead electrode inserted into the opening of the substrate and in contact with the pad.
A method of fabricating a display device, the method comprising:
- providing a substrate;
- defining a groove in the substrate by performing a first etching process on an upper surface of the substrate;
- forming a pad clad which is accommodated in the groove and includes a pad contact hole;
- forming a pad disposed on the pad clad and inserted into the pad contact hole;
- forming a transistor on the pad and forming a fan-out line electrically connecting the pad with the transistor;
- defining an opening exposing the pad by performing a secondary etching process on a lower surface of the substrate;
- and
- inserting one side of a flexible film into the opening to bring a lead electrode of the flexible film in contact with the pad.
