Abstract:
A flexible printed circuit film connects a substrate with a printed circuit board. The flexible printed circuit film includes a first area configured to be attached to the substrate; a second area configured to be connected with the printed circuit board; and a third area between the first area and the second area. Each of the first area and the third area has a trapezoid shape with a width that gradually decreases in a direction toward the second area, and the second area has a rectangular shape.
