Flexible printed circuit board, display device, electronic device, and method for manufacturing a display device

A method for manufacturing a display device, comprising:

• preparing a display panel comprising panel pads arranged along a first direction;
• preparing a flexible printed circuit board comprising a base portion, a first protrusion, a second protrusion, first connection pads, and second connection pads, wherein the first protrusion protrudes in a second direction intersecting the first direction from one side of the base portion extending in the first direction, the second protrusion protrudes in the second direction from the one side of the base portion and spaced apart from the first protrusion in the first direction, the first connection pads are disposed on the first protrusion, and the second connection pads are disposed on the second protrusion;
• aligning the flexible printed circuit board on the display panel by adjusting a position of the first protrusion using a first alignment head and adjusting a position of the second protrusion using a second alignment head;
• preliminarily pressing the display panel and the flexible printed circuit board;
• and
• finally pressing the display panel and the flexible printed circuit board.

A flexible printed circuit board comprising:

• a base portion extending in a first direction;
• a first protrusion protruding in a second direction intersecting the first direction from one side of the base portion;
• a second protrusion protruding in the second direction from the one side of the base portion and spaced apart from the first protrusion in the first direction;
• first connection pads disposed on the first protrusion;
• and
• second connection pads disposed on the second protrusion,
• wherein at least some of the first connection pads extend in a direction inclined with respect to the first direction and the second direction, and
• wherein at least some of the second connection pads extend in a direction inclined with respect to the first direction and the second direction.
