         [0022]      FIG. 1  shows a top plan view of a display device according to an exemplary embodiment of the present invention.  FIG. 2  shows a top plan view of a rear side of a display device of  FIG. 1 . 
         [0023]    Referring to  FIG. 1  and  FIG. 2 , the display device  1000  includes a display panel  100  for displaying an image, and a first printed circuit board (PCB)  200  and a second printed circuit board (PCB)  300  for applying a driving signal to the display panel  100 . 
         [0024]    The display panel  100  may include two thin substrates that face each other and are formed with an insulating material, such as glass or plastic, and a liquid crystal layer disposed between the substrates. A thin film, which may include a plurality of thin film transistors, a plurality of data lines, a plurality of gate lines, and a plurality of pixel electrodes may be disposed on one of the substrates. Another thin film, which may include a color filter and a common electrode, may be disposed on the other substrate. 
         [0025]    Further, the display panel  100  may include a liquid crystal layer disposed between the substrates. The display panel  100  may include an insulating material made of a transparent material. A thin film, which may include a plurality of thin film transistors, a plurality of data lines, a plurality of gate lines, and a plurality of pixel electrodes disposed on one of the substrates. A common electrode, and a color filter may be further disposed on one of the substrates. Here, the liquid crystal layer may be provided in a space between the pixel electrode and the common electrode to which a common voltage is applied. 
         [0026]    The display panel  100  may include a substrate formed with an insulating material, such as transparent glass or plastic, and may include a plurality of organic light emitting diodes. A thin film, including a plurality of thin film transistors, a plurality of gate lines, and a plurality of data lines may be disposed on the substrate. The display panel  100  may also include an encapsulation substrate that is disposed on the thin film, which is combined by a substrate and a sealant, and operates as a sealing substrate. 
         [0027]    Referring back to  FIGS. 1 and 2 , the first PCB  200  is attached to a rear side of the display panel  100 , and is connected to the second PCB  300  through a first connecting film  400 . The second PCB  300  is connected to the display panel  100  through a plurality of second connecting films  500 . The first connecting film  400  is disposed between the second connecting films  500 . 
         [0028]    The first PCB  200  may receive an image signal from an external device and transmit a driving signal for driving the display panel  100  to the second PCB  300 . The second PCB  300  may apply the driving signal provided by the first PCB  200  to the display panel  100 . 
         [0029]    The first connecting film  400  and the second connecting films  500  may be flexible and may include wires. The first connecting film  400  is longer than the second connecting films  500 . 
         [0030]    The second connecting films  500  are attached to the rear side of the display panel  100  by an adhesive film  150 . 
         [0031]    A method for manufacturing a display device according to an exemplary embodiment of the present invention will now be described with reference to  FIG. 2  to  FIG. 7   
         [0032]      FIG. 3  and  FIG. 4  show a method for manufacturing a display device according to an exemplary embodiment of the present invention.  FIG. 5  shows a perspective view of a manufacturing method shown in  FIG. 4 .  FIG. 6  shows a fixing member according to an exemplary embodiment of the present invention.  FIG. 7  shows a cross-sectional view with respect to a line VII-VII of  FIG. 5 . 
         [0033]    Referring to  FIG. 3 , the display panel  100 , the first PCB  200 , and the second PCB  300  are provided, and the first PCB  200  is connected to the second PCB  300 . The first PCB  200  and the second PCB  300  are connected by the first connecting film  400 . 
         [0034]    Referring to  FIG. 4  to  FIG. 7 , the second PCB  300  is connected to the display panel  100 . Here, the second PCB  300  is connected to the display panel  100  by a plurality of second connecting films  500 . 
         [0035]    The first PCB  200  and the first connecting film  400  are fixed by a fixing member  600 . The plurality of second connecting films  500  are attached to the rear side of the display panel  100  by the adhesive film  150 . 
         [0036]    The first PCB  200  is connected to the second PCB  300  by the first connecting film  400 . The first connecting film  400  is longer than the second connecting film  500 . In this configuration, attachment of the second connecting film  500  to the rear side of the display panel  100  is interfered with by the first connecting film  400 , because of flexibility of the first connecting film  400 . 
         [0037]    Therefore, the second connecting films  500  are attached to the rear side of the display panel  100  after the first PCB  200  and the first connecting film  400  are fixed, so that they do not overlap the display panel  100 . 
         [0038]    The first connecting film  400  may be fixed in a folded position using an adhesive film, so that it does not overlap the display panel  100 . However, when the adhesive film is removed, an adhesive material of the adhesive film remains on the first connecting film  400 . 
         [0039]    In the present exemplary embodiment, however, the fixing member  600  is used to fix the first PCB  200  and the first connecting film  400  so they do not overlap with the display panel  100 , and the second connecting films  500  are then attached to the rear side of the display panel  100 . 
         [0040]    The fixing member  600  includes a first settler  610 , a second settler  620 , and a connector  630  connecting the first settler  610  and the second settler  620 . 
         [0041]    The first settler  610  and the second settler  620  are U-shaped and may be flexible. The first settler  610  is bigger than the second settler  620 . Further, an extended line on an upper side of the first settler  610  and an extended line on an upper side of the second settler  620  are provided on a same line. That is, the upper surfaces of the first and second settlers are on the same horizontal plane as one another. 
         [0042]    When the first PCB  200  and the first connecting film  400  are fixed by the fixing member  600 , the PCB  200  is held by the first settler  610 , and the second PCB  300  is held by the second settler  620 . The first connecting film  400  is provided on the fixing member  600 . 
         [0043]    Therefore, the first PCB  200  and the first connecting film  400  do not overlap the display panel  100 . When the second connecting films  500  are attached to the rear side of the display panel  100 , the first connecting film  400  does not cause any interference with the process. 
         [0044]    Since the first settler  610  and the second settler  620  may be flexible, it is easy to dispose the first PCB  200  and second PCB  300  in the first settler  610  and the second settler  620 . 
         [0045]    Referring back to  FIG. 2 , the fixing member  600  is removed and the first PCB  200  is attached to the rear side of the display panel  100 . 
         [0046]    Accordingly, the second PCB  300  is connected to the display panel  100  by the second connecting films  500 , the fixing member  600  is used to fix the first PCB  200  and the first connecting film  400  to the display panel  100 , and the second connecting films  500  are attached to the display panel  100 . Accordingly, in an exemplary embodiment of the present invention, the first connecting film  400  is held in position so as not to interfere with the attachment of the second connecting films  500  to the display panel  100 . 
         [0047]    While this invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
