Patent ID: 8724069

Claim:
A liquid crystal display device comprising: a first flexible circuit board in which a liquid crystal display panel having an image display surface, and a rear surface which is opposite the display surface, a connection terminal for being electrically connected to the liquid crystal display panel, and an external terminal for being electrically connected to the outside are formed; and a second flexible circuit board which includes a mounting portion for mounting light emission components, and an extended portion for being electrically connected to the first flexible circuit board, wherein the mounting portion is arranged in the rear surface side of the liquid crystal display panel by making a surface on which the light emission components are mounted face the rear surface of the liquid crystal display panel, wherein a portion of the first flexible circuit board at which the connection terminal is formed is bonded to an end portion of the display surface side of the liquid crystal display panel, is pulled out from the end portion of the liquid crystal display panel, and is bent and overlapped with a surface opposite the surface on which the light emission components of the mounting portion are mounted with a space, in which the external terminal is arranged in the rear surface, wherein the extended portion is pulled out from the mounting portion, is bent so as to return to the direction of the mounting portion, and is overlapped with the first flexible circuit board on an outer surface of the first flexible circuit board, wherein the first flexible circuit board includes a first bent portion which is convex in the direction away from the end portion of the liquid crystal display panel, and is extended to the rear surface side of the liquid crystal display panel from the connection terminal which is connected to the liquid crystal display panel through the first bent portion, and wherein the extended portion is arranged at the rear surface side rather than the first flexible circuit board which is arranged at the rear surface side of the liquid crystal display panel through a second bent portion which is convex in the direction opposite to the first bent portion from the first flexible circuit board on the rear surface side of the liquid crystal display panel, and is connected to the mounting portion through a third bent portion which is convex in the same direction as the first bent portion.
