Abstract:
1. A display device comprising: a first flexible printed circuit board having a group of interface terminals; a second flexible printed circuit board which is joined to the first flexible printed circuit board and is electrically connected to at least one terminal of the group of interface terminals; a display panel which is electrically connected and joined to the first flexible printed circuit board; and a sub panel which is arranged on an upper surface of the display panel in an overlapping manner, and is electrically connected and joined to the second flexible printed circuit board, wherein the first flexible printed circuit board extends sideward from an end portion of the display panel, is bent in a return direction toward the display panel, and extends to an area below a lower surface of the display panel, and the second flexible printed circuit board includes: an upper end portion which extends sideward from an end portion of the sub panel above the first flexible printed circuit board; an outward bent portion which is bent from the upper end portion in a return direction toward the display panel; an intermediate portion which extends from the outward bent portion in such a manner that the intermediate portion passes an electrically connecting portion with the first flexible printed circuit board below the first flexible printed circuit board; an inward bent portion which is bent from the intermediate portion in a return direction toward the outward bent portion and toward the electrically connecting portion; and a lower end portion which extends from the inward bent portion and reaches the electrically connecting portion.
