Claims (14)

1. A method for fixing a printed circuit board on a display panel, comprising:

coupling the display panel with a mold frame, the display panel having the printed circuit board electrically connected to the display panel;

positioning the printed circuit board on a rear surface of the display panel;

attaching a first double-sided tape on a first insulating film;

aligning the first insulating film to cover the outer surface of the printed circuit board; and

attaching the first insulating film to a first portion of the mold frame and the printed circuit board using the first double-sided tape, the first insulating film covering an outer surface of the printed circuit board and one side of the mold frame, wherein the first insulating film has a protruding portion protruding toward another side of the mold frame.

2. The method according to claim 1 , further comprising:

attaching a second double-sided tape on the second insulating film;

aligning the second insulating film to cover the protruding portion of the first insulating film; and

attaching the second insulating film to a second portion of the mold frame and the first insulating film using the second double-sided tape, the second insulating film covering a protruding portion and the other side of the mold frame so that the printed circuit board is fixed to the mold frame.

3. A method for fixing a printed circuit board on a display panel, comprising:

coupling a mold frame with the display panel, the display panel having a printed circuit board positioned at a rear surface of the display panel and electrically connected to a pad portion of the display panel;

attaching a first insulating film to the mold frame and the printed circuit board using a first double-sided tape, the first insulating film covering an outer surface of the printed circuit board and one side of the mold frame, wherein the first insulating film has a protruding portion protruding toward another side of the mold frame; and

attaching a second insulating film to the mold frame and the first insulating film using a second double-sided tape, the second insulating film covering the protruding portion and the other side of the mold frame so that the printed circuit board is fixed to the mold frame.
