Display device

An electronic apparatus comprising:

• a first base portion including a display area including a plurality of pixels connected to corresponding signal lines and a non-display area positioned around the display area and having a pad area;
• and
• a printed circuit film attached to the pad area of the first base portion,
• wherein a plurality of pad electrodes arranged on the first base portion in a first direction and a first panel alignment mark positioned on one side of the plurality of pad electrodes in the first direction are disposed in the pad area,
• a first protective layer is disposed on the pad electrodes, a plurality of first open portions each of which exposes a portion of an upper surface of each pad electrode is defined in the first protective layer,
• the printed circuit film includes a third base portion and a plurality of lead electrodes disposed on a lower surface of the third base portion and electrically connected to the plurality of pad electrodes, respectively,
• the first panel alignment mark includes a first panel alignment metal portion, and a first panel alignment insulating portion disposed on the first panel alignment metal portion and positioned on a same layer as the first protective layer, and a second open portion penetrating the first panel alignment metal portion in a thickness direction and surrounded by the first panel alignment metal portion on a plane,
• the first panel alignment mark and the pad electrode are positioned on a same layer,
• the first panel alignment insulating portion is spaced apart from the first protective layer, and
• the first panel alignment metal portion defines a closed loop surrounding the second open portion,
• wherein each of the plurality of pad electrodes comprises a first pad portion and a second pad portion disposed on the first pad portion without any insulating layer therebetween, and the first pad portion is physically connected to one of the corresponding signal lines,
• wherein each of the plurality of lead electrodes in the printed circuit film is electrically connected to the second pad portion,
• wherein the second pad portion includes a first surface facing an upper surface of the first pad portion and a second surface opposite to the first surface, and an entirety of the first surface of the second pad portion is in direct contact with an entirety of the upper surface of the first pad portion, and
• wherein the second surface of the second pad portion is in direct contact with a conductive material through which the lead electrode is electrically connected to the second pad portion.
