Display Device

Abstract

A display device includes a first substrate which constitutes a part of a display panel, the first substrate having a first side and having a terminal formed thereon adjacent to the first side, and a flexible printed circuit board which is connected to the first substrate. The flexible printed circuit board includes a board portion, a wiring layer which is mounted on the board portion, a cover portion which covers the wiring layer, and a connecting portion which is connected to the terminal formed on the first substrate. The connecting portion includes a metal layer, and wherein the cover portion overlaps with the first side and an area between the first side and the terminal.

What is claimed is: 
     
         1 . A display device comprising:
 a first substrate which constitutes a part of a display panel, the first substrate having a first side and having a terminal formed thereon adjacent to the first side; and   a flexible printed circuit board which is connected to the first substrate;   wherein the flexible printed circuit board includes a board portion, a wiring layer which is mounted on the board portion, a cover portion which covers the wiring layer, and a connecting portion which is connected to the terminal formed on the first substrate;   wherein the connecting portion includes a metal layer; and   wherein the cover portion overlaps with the first side and an area between the first side and the terminal.   
     
     
         2 . A display device according to  claim 1 , wherein the cover portion in the vicinity of the connecting portion is fixed to the first substrate using a resin or an adhesive agent. 
     
     
         3 . A display device according to  claim 1 , wherein the cover portion in the vicinity of the connecting portion is fixed to the terminal formed on the first substrate. 
     
     
         4 . A display device according to  claim 1 , wherein a Ni layer is formed on a first-substrate-side surface of the connecting portion, and the Ni layer has a thickness of at least 10 μm. 
     
     
         5 . A display device according to  claim 1 , wherein the display panel is a liquid crystal display panel, the display device includes a backlight which is arranged on a rear surface side of the liquid crystal display panel, the backlight includes a frame-shaped mold, and the flexible printed circuit board is folded and has a portion thereof arranged on a rear surface side of the frame-shaped mold.
