     MODE FOR CARRYING OUT THE INVENTION 
     Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. The spirit and scope of the present disclosure, however, shall not be construed as being limited to embodiments provided herein. Rather, it will be apparent that other embodiments that fall within the spirit and scope of the present disclosure may easily be derived through adding, modifying, and deleting elements herein. 
     The meaning of ‘comprises’ and/or ‘comprising’ specifies a property, a region, a fixed number, a step, a process, an element and/or a component but does not exclude other properties, regions, fixed numbers, steps, processes, elements and/or components. 
       FIG. 1  is a partial sectional view illustrating a display apparatus according to an embodiment. 
     Referring to  FIG. 1 , a display panel  20  may include a front plate and a rear plate that are vertically coupled. The display panel  20  may be one of various display panels such as liquid crystal displays (LCDs), plasma display panels (PDPs), electro luminescent displays (ELDs), vacuum fluorescent display (vacuum fluorescent displays). A case  10  encloses the rear side of the display panel  20 . The case  10  may include a cabinet  11  and a back cover  12 . 
     The display apparatus of the current embodiment may include a printed circuit board  30  configured to control operations of the display panel  20 , a heat dissipation plate  40  configured to dissipate heat from the display panel  20  and the printed circuit board  30 , and a front filter  50  disposed at the front side of the display panel  20 . 
     When images are displayed on the display panel  20 , light emitted from the display panel  20  passes through the front filter  50 . For example, the front filter  50  may be formed of a transparent glass material. In addition, the front filter  50  may be formed of a strengthened glass material for satisfying strength requirements of a large display apparatus. However, materials that can be used to form the front filter  50  are not limited thereto. For example, the front filter  50  may be formed of a transparent plastic material. That is, the front filter  50  may be formed of any material that is transparent and has a desired strength. 
     In addition, the front filter  50  may include a plurality of functional layers such as a non-reflection layer, an optical characteristic layer, an electromagnetic interference (EMI) shield layer, and a near infrared (NIR) shield layer. Alternatively, the front filter  50  may be formed of only glass or transparent plastic for transmitting light emitted from the display panel  20  and protecting the display panel  20 . 
     As shown in  FIG. 1 , the display panel  20  and the front filter  50  may be spaced a predetermined distance from each other. For example, an air gap may be formed between the display panel  20  and the front filter  50 . 
     The display apparatus of the current embodiment may include a gasket  13  and a filter support  14  to support the front filter  50  and connect the front filter  50  to the back cover  12 . In addition, the display apparatus may further include a module supporter  15  to support a display module formed by coupling the printed circuit board  30  and the display panel  20 . 
       FIG. 2  is a partial sectional view illustrating the display panel  20  and the front filter  50  of the display apparatus. The display panel  20  and the front filter  50  may be disposed with a predetermined distance (d) therebetween. 
     Referring to  FIG. 2 , light emitted from the display panel  20  reaches a user side through the front filter  50  so that a user can see images displayed on the display panel  20 . 
     At this time, a portion of light emitted from the display panel  20  is reflected from the front filter  50  to the display panel  20  where the portion of the light is re-reflected. The re-reflected portion reaches the user side through the front filter  50 . 
     Due to such reflection of light between the display panel  20  and the front filter  50 , a display image may be seen by a user as a double image (image doubling phenomenon). 
     If a watching angle of a user is θ, a double image distance (D) may be calculated by Formula 1. 
         D= 2 d ·tan θ  [Formula 1]
 
     As the distance (d) between the display panel  20  and the front filter  50  increases, the double image distance (D) increases, and thus a user may see a more serious double image. On the other hand, if the distance (d) between the display panel  20  and the front filter  50  decreases, the double image distance (D) decreases. 
     Table 1 shows results of an experiment carried out to measure user&#39;s perception of image doubling phenomenon with reference to the double image distance (D). While decreasing the double image distance (D) from 10 mm to 0.5 mm, it was counted how many subjects perceive the image doubling phenomenon. Table 1 shows the percentage of subjects who perceived the image doubling phenomenon with respect to the double image distance (D). 
     Since subjects might easily perceive the image doubling phenomenon as they got closer to the display apparatus, the distance between the subjects and the display apparatus was fixed. Users usually watch broadcasting programs at positions spaced apart from display apparatuses by 1 m or more. Therefore, the distance between the subjects and the display apparatus was set to about 1 m.

     Referring to Table 1, most of the subjects perceived the image doubling phenomenon when the double image distance (D) was from 10 mm to 8.5 mm, and the number of subjects perceived the image doubling phenomenon was reduced as the double image distance (D) was reduced from 8.5 mm. When the double image distance (D) was 6.5 mm or smaller, more than 50% of the subjects did not perceive the image doubling phenomenon. 
     Particularly, referring to Table 1 and  FIG. 3  showing a graph plotted using the data of Table 1, when the double image distance (D) was reduced to 6 mm, the percentage of subjects perceived the image doubling phenomenon was steeply reduced to 4%. 
     That is, if the double image distance (D) is 6 mm or smaller, most of users may not perceive the image doubling phenomenon. In other words, if the double image distance (D) is 6 mm or smaller, image quality that users feel may be improved. 
     In addition, since users may watch a broadcasting program through the display panel  20  in a state where they sit or stand at positions spaced apart from the display apparatus by 1 m or more, the angle between the direction of user&#39;s eyes and the display panel  20  may not be greater than 45 degrees. That is, generally, a seeing angle θ is not greater than 45 degrees. Thus, in Formula 1, the minimum value of tan θ may be 0, and the maximum value of tan θ may be 1. 
     If the range of tan θ (0≦tan θ≦1) calculated based on the range of the seeing angle θ is input to Formula 1, the double image distance (D) ranges as follows. 
       0≦ D≦ 2 d   [Formula 2]
 
     Referring to Formula 2, if the distance (d) between the display panel  20  and the front filter  50  is adjusted to 3 mm or smaller, the double image distance (D) can be 6 mm or smaller to make a user perceive no image doubling phenomenon as described with reference to Table 1. 
     That is, it may be necessary to keep the distance (d) between the display panel  20  and the front filter  50  equal to or smaller than 3 mm so as to make a user watch a broadcasting program without perceiving image doubling phenomenon and image quality deterioration when the user watch the broadcasting in front of the display panel  20 . 
     However, as shown in  FIG. 1 , the distance (d) between the display panel  20  and the front filter  50  may be required to greater than the thickness of the filter support  14  when the filter support  14  is disposed between the display panel and the front filter  50  and is grounded to the rear surface of the front filter  50 . 
       FIG. 4  is a perspective view illustrating a display apparatus according to another embodiment. In the following description of the display apparatus of  FIG. 4 , the same elements as those shown in  FIGS. 1 to 3  will not be described again. 
     Referring to  FIG. 4 , in the current embodiment, a display module is not protected by an additional front cabinet. Instead, a front filter  100  forms the entire front side of the display apparatus. 
     In the case, the horizontal and vertical lengths of the front filter  100  may be equal to or greater than the horizontal and vertical lengths of a back cover  200 . 
       FIG. 5  is a partial sectional view illustrating the display apparatus of  FIG. 4 , according to a first embodiment. The structure of the display apparatus of the first embodiment will now be described in detail with reference to  FIG. 5 . 
     As shown in  FIG. 5 , the back cover  200  encloses the rear side of a display module  140  including a display panel in which a front plate and a rear plate are coupled to each other. The display module  40  may be coupled to a frame  400  fixed to the rear side of the front filter  10 . 
     The frame  400  may be fixed to the rear side of the front filter  100  by using an adhesive member (not shown) or an adhesive. A double-sided adhesive tape may be used as the adhesive member. After the frame  400  is fixed to the rear side of the front filter  100 , the frame  400  is located inward from the outer edge of the front filter  100  by a predetermined length so that the frame  400  may not seen when viewed from the front of the display apparatus. 
     The back cover  200  may include a body part  210  and an extension  220 . The body part  210  forms the exterior of the back cover  200 , and the extension  220  extends from the body part  210  and is grounded to a supporter  300 . The back cover  200  may be coupled to the frame  400  using coupling members  170 . For this, coupling holes may be formed in the extension  220  for the coupling members  170 . As described above, an end of the supporter  300  is fixed to and grounded to the rear side of the front filter  100 , and the other end of the supporter  300  is grounded to the extension  220  of the back cover  200 . Therefore, the rear side of the front filter  100  can be electrically connected to the back cover  200  through the supporter  300 . In detail, a ground part of an EMI shield layer disposed on the rear side of the front filter  100  can be electrically connected to the back cover  200  through the supporter  300 . 
     According to the embodiments shown in  FIGS. 4 and 5 , since the front filter  100  formed of a glass material forms the entire front side of the display apparatus, the front side of the display apparatus can be aesthetically improved and may look bigger. 
     In the embodiment shown in  FIG. 4 , it may be necessary to keep the distance (d) between the front filter  100  and the display panel included in the display module  140  equal to or smaller than 3 mm, so as to prevent the image doubling phenomenon and resulting image quality deterioration as described above. In this case, however, it may not be easy to dispose the supporter  300  between the display panel and the front filter  100 . 
     Therefore, as shown in  FIG. 6 , the supporter  300  may not be disposed between the front filter  100  and the display panel of the display module  140 . Instead, the supporter  300  may be fixed to the rear side of the front filter  100  at an outer region of the display panel. 
       FIG. 7  is a rear view illustrating a display module according to an embodiment. A printed circuit board  30  may be disposed at a rear side  31  of the display module. The printed circuit board  30  includes circuits for operating a display panel  20 . 
     Referring to  FIG. 7 , horizontal and vertical frames  32  and  33  and a module driving unit  34  may be disposed on the rear side  31  of the display module. The vertical frames  32  and  33  support the display module in horizontal and vertical directions. The module driving unit  34  sends driving signals to the display panel  20 . 
     In addition, an input/out board  35  may be disposed on the rear side  31  of the display module  30 . The input/output board  35  includes input terminals to receive audio and video signals from external devices, and output terminals to output audio and video signals to external devices. The input/output board  35  may be fixed to the rear side  31  of the display module  30  using a connection member  36 . 
     The module driving unit  34  may include a plurality of driver integrated circuits (ICs) for supplying driving signals to electrodes of the display panel  20 . 
     A heat sink  39  may be disposed at a position close to the driver ICs for dissipating heat from the driver ICs. For example, the heat sink  39  may be fixed to a lower side of the display module for dissipating heat from a data driver IC (not shown) used to supply data signals to the display panel  20 . 
     As shown in  FIG. 7 , the heat sink  39  may be disposed on the lower side of the display module around a data driver IC (not shown) to dissipate heat from the data driver IC packed in a tape carrier package (TCP) for preventing the data driver IC from being damaged by overheat. 
     The heat sink  39  may be formed of an aluminum material because aluminum has high thermal conductivity and can be easily shaped through an extrusion process. 
       FIG. 8  is a sectional view illustrating the display apparatus of  FIG. 4 , according to a third embodiment. In detail,  FIG. 8  is a sectional view taken along line B-B of  FIG. 4  to show a lower structure of the display apparatus. In the following description, the same elements as those described with reference to  FIGS. 1 to 7  will not be described again. 
     Referring to  FIG. 8 , a driver IC  144  is disposed on a TCP film  145  connected to a display panel  141  for supplying driving signals to electrodes of the display panel  141  through the TCP film  145 . 
     In an embodiment, a rear plate  143  of the display panel  141  may be electrically connected to a data driver board (not shown) through the TCP film  145  and the driver IC  144  so that data signals can be supplied to address electrodes of the rear plate  143  of the display panel  141 . 
     A heat dissipation plate (not shown) may be attached to the rear side of the rear plate  143  of the display panel  141 , and a TCP support frame (not shown) may be disposed on the rear side of the rear plate  143  of the display panel  141  for supporting the TCP film  145 . In this case, the driver IC  144  may be disposed at the TCP support frame (not shown). 
     A heat sink  146  may surround at least portions of the driver IC  144  and the TCP film  145  for dissipating heat from the driver IC  144  to surrounding air. The heat sink  146  may be attached to the driver IC  144  using a thermal tape (not shown). 
     As shown in  FIG. 8 , the heat sink  146  of the display apparatus of the embodiment may extend close to the front filter  100 , and a front end  147  of the heat sink  146  close to the front filter  100  may be bent in a direction parallel with the front filter  100 . For example, the front end part  147  of the heat sink  146  may be bent toward the display panel  141  in a direction parallel with the front filter  100  for efficient use of the inside space of the display apparatus. For example, if the front filter  100  of the display apparatus is impacted, the display panel  141  may be damaged, or the distance (d) between the front filter  100  and the display panel  141  may be changed to vary the optical characteristics of the display apparatus and deteriorate the image quality of the display apparatus. 
     In addition, if the distance (d) between the display panel  141  and the front filter  100  is decreased to, for example, 3 mm or smaller, an external impact may be directly transmitted to the display panel  141 . In this case, the display panel  141  may be largely damaged or image quality may be largely decreased. 
     Therefore, as shown in  FIG. 8 , the front end part  147  of the heat sink  146  is disposed close to the front filter  100  to protect the display panel  141  from an external impact or prevent variation of the distance (d) between the front filter  100  and the display panel  141 . 
     In addition, since the front end part  147  of the heat sink  146  is bent, deflection of the heat sink  146  can be prevented, and thus the stiffness of the display module  140  can be increased for resisting against external impacts. 
       FIG. 9  is an enlarged sectional view illustrating a portion indicated by a dot-and-chain line in  FIG. 8 , according to an embodiment. 
     Referring to  FIG. 9 , a distance (c) between the front end part  147  of the heat sink  146  and the front filter  100  may be smaller than the distance (d) between the display panel  141  and the front filter  100 . Therefore, although the front filter  100  or the display module including the display panel  141  is impacted, the front filter  100  and the display panel  141  may not collide with each other. Thus, the front filter  100  or the display panel  141  can be protected, and the distance (d) between the display panel  141  and the front filter  100  can be kept constant. 
     When the distance (d) between the display panel  141  and the front filter  100  is adjusted to 3 mm or smaller for making a user perceive no image doubling phenomenon, the distance (c) between the front end part  147  of the heat sink  146  and the front filter  100  may be adjusted to 1.5 mm or smaller for protecting the display panel  141  or other parts and keep the distance (d) constant. 
     In addition, if the heat sink  146  is close to the front filter  100  as described above, a distance (a) between the front end part  147  of the heat sink  146  and the supporter  300  is very small, and thus heat can be dissipated through the heat sink  146  more effectively. 
     Thus, the distance (a) between the front end part  147  of the heat sink  146  and the supporter  300  may be smaller than a distance (b) between the display panel  141  and the support part  300 . When the thickness (e) of the support part  300  is considered, the distance (a) may be adjusted to 0.9 mm or smaller so as to prevent damage of the display panel  141 , keep the distance (d) constant, and facilitate heat dissipation. 
     Referring to  FIG. 10 , an adhesive layer  148  is disposed between the front end part  147  of the heat sink  146  and the support part  300  for fixing the heat sink  146  to the support part  300 . In this case, the display panel  141  may be protected more surely, and the distance (d) can be kept constant more surely. 
     In addition, if the adhesive layer  148  is formed of an elastic material capable of absorbing shock, the display panel  141  or the front filter  100  may be less damaged because the adhesive layer  148  absorbs an impact. 
     For example, the adhesive layer  148  disposed between the front end part  147  of the heat sink  146  and the support part  300  is a thermally conductive tape. In this case, the heat dissipating effect of the heat sink  146  may largely be improved, and the display apparatus may be less impacted owing the adhesive layer  148 . 
     Alternatively, the front end part  147  of the heat sink  146  may make contact with the support part  300  for protecting the display panel  141  or the front filter  100  and facilitating heat dissipation as described above. 
       FIG. 11  is a perspective view illustrating the heat sink  146  according to an embodiment. Referring to  FIG. 11 , the heat sink  146  may have a U-shaped. That is, the front end part  147  of the heat sink  146  may be bent toward the display panel  141  as described with reference to  FIGS. 8 to 10 , and a rear end of the heat sink  146  may be coupled to the rear side of the display module after being bent one or more times in parallel with the front end part  147 . 
       FIG. 12  is a perspective view illustrating horizontal and vertical frames disposed at the rear side of the display module according to an embodiment. 
     Referring to  FIG. 12 , a main frame  500  is provided for coupling with the rear side of a display panel. The main frame  500  includes one or more horizontal frames  510  and  520  and a vertical frame  530 . 
     The horizontal frames  510  and  520  extend horizontally on the main frame  500  for improving the rigidity of the display module by horizontally supporting the display module. The vertical frame  530  extends vertically on the main frame  500  for improving the rigidity of the display module by vertically supporting the display module. As shown in  FIG. 12 , two vertically frames  510  and  520  may be disposed at upper and lower positions of the main frame  500 , and a vertical frame  530  may be disposed at one of left and right positions of the main frame  500 . In addition, the vertical frame  530  may be fixed to the main frame  500  using at least one coupling members  535 . 
     In the case of the display apparatus of the embodiment, the horizontal frame  530  disposed at the upper position of the main frame  500  may be close to the upper end of the main frame  500  so as to prevent the display module from deflecting downward from the horizontal frame  530 . In this case, the rigidity of the display module can be improved. 
     For example, in the case where the distance between the display module and the front filter is adjusted to 3 mm or smaller so as to make a user perceive no image doubling phenomenon as described above, the display module may easily broken by an impact. That is, if the display module is bent by an impact, since the distance between the display module and the front filter is small, the front filter or the display panel may be broken by collision. 
     Therefore, as shown in  FIG. 12 , the rigidity of the display module can be increased by adjusting a distance (a 1 ) between the horizontal frame  510  and the upper end of the main frame  500  to be smaller than a distance (a 2 ) between the horizontal frame  520  and the lower end of the main frame  500 , so as to protect the display module from impacts even when the distance between the display module and the front filter is 3 mm or smaller. 
       FIG. 13  is a view illustrating packing members for a display apparatus according to an embodiment. As shown in  FIG. 13 , a plurality of packing members  600 ,  610 ,  620 ,  630 ,  640 , and  650  may be used, which accommodate portions of a display apparatus, respectively. 
     Referring to  FIG. 13 , a display apparatus package may include: an upper packing member  600  to accommodate an upper center part of the display apparatus including a back cover  550 ; a lower packing member  610  to accommodate a lower center part of the display apparatus; two left packing members  620  and  630  to accommodate left corners of the display apparatus, respectively; and two right packing members  640  and  650  to accommodate right corners of the display apparatus, respectively. 
     Each of the packing members  600 ,  610 ,  620 ,  630 ,  640 , and  650  includes an insertion recess to receive a part of the display apparatus and is formed of an elastic material capable of absorbing shock. For example, the packing members  600 ,  610 ,  620 ,  630 ,  640 , and  650  may be formed of an elastic material such as Styrofoam or rubber for absorbing shocks so that the display apparatus can be less impacted. 
       FIG. 14  is a sectional view taken along line B-B of  FIG. 13  for illustrating the display apparatus and the packing members according to an embodiment. 
     Referring to  FIG. 14 , as described above, since the (upper) horizontal frame  510  is disposed close to the upper end of the main frame  500 . Therefore, when the upper center part of the display apparatus is accommodated in the upper packing member  500 , at least a portion of the horizontal frame  510  is overlapped with the upper packing member  500 . 
     As described above, since the upper horizontal frame  510  is close to the upper end of the main frame  500  so that the horizontal frame  510  can be overlapped with the upper packing member  500 , when the display apparatus is accommodated in the packing members  600 ,  610 ,  620 ,  630 ,  640 , and  650 , at least a portion of the horizontal frame  510  can be inserted in the insertion recess of the upper packing member  500 . 
     Therefore, when the display apparatus is carried or processed in a state where the display apparatus is accommodated in the packing members  600 ,  610 ,  620 ,  630 ,  640 , and  650 , a display module of the display apparatus can be stably supported and impacts can be absorbed although the display apparatus is impacted. Thus, the rigidity of the display apparatus can be improved. 
     Referring to  FIG. 15 , the horizontal frame  510  may extend to regions of the packing members  620  and  640  that accommodate upper left and right parts of the display apparatus. Therefore, when the display apparatus is accommodated in the packing members  600 ,  610 ,  620 ,  630 ,  640 , and  650 , both ends of the horizontal frame  510  can be inserted in the insertion recesses of the packing members  620  and  640 . 
     Therefore, when the display apparatus is carried or processed in a state where the display apparatus is accommodated in the packing members  600 ,  610 ,  620 ,  630 ,  640 , and  650 , the display module of the display apparatus can be stably supported and impacts can be absorbed although the display apparatus is impacted. 
     In addition, as shown in  FIG. 15 , vertical frames  530  and  540  may be vertically disposed at left and right positions of the main frame  500 , respectively. 
       FIGS. 16 and 17  are schematic sectional views illustrating front filter structures including an EMI shield layer according to embodiments. A front filter  100  includes a glass  110  and an EMI shield layer  120  disposed on a rear surface of the front filter  100 . 
     Referring to  FIG. 16 , the EMI shield layer  120  may be a mesh EMI shield layer formed by patterning a metal layer in a mesh shape to shield electromagnetic waves. 
     As described above, if the distance (d) between the front filter  100  and a display panel of a display module  140  is very small at about 3 mm or smaller, the EMI shield layer  120  may be brought into contact with the display module  140  (in detail, the display panel of the display module  140 ) due to an impact applied to the display apparatus, and thus mesh patterns of the EMI shield layer  120  may be worn down. 
     In this case, the image quality and EMI shielding of the display apparatus can be deteriorated due to particles generated by abrasion of the mesh patterns of the EMI shield layer  120 . 
     Therefore, as shown in  FIG. 17 , a protective layer  121  is disposed between the display module  140  and the EMI shield layer  120  of the front filter  100  to prevent abrasion of the mesh patterns of the EMI shield layer  120 . 
     The protective layer  121  may be formed of polyethylene terephthalate (PET). An adhesive layer (not shown) may be disposed on the EMI shield layer  120  so that the protective layer  121  can be bonded to the EMI shield layer  120 . 
     As the distance (d) between the front filter  100  and the display panel of the display module  140  is reduced, light reflected from the display module  140  may interfere with light reflected from the front filter  100 . Such interference includes destructive interference and constructive interference. If destructive interference occurs, light phases cancel each other and thus it looks dark, and if constructive interference occurs, light phases are added together and thus it looks bright. Due to the above-described light interference, circular rings known as Newton&#39;s ring may appear on a screen as shown in  FIG. 18 . The brightness uniformity of a display image may be deteriorated due to such Newton&#39; rings, and thus the image quality may be decreased. 
     Table 2 below shows results of measurement carried out to check generation of the image doubling phenomenon according to the distance (d) between the front filter  100  and the display panel of the display module  140 .

     Referring to Table 2, if the distance (d) between the front filter  100  and the display panel of the display module  140  is very small at 1.4 mm or smaller, Newton&#39;s rings may occur by interference between reflected light rays. 
       FIGS. 19 to 22  are schematic sectional views illustrating display apparatus structures including anti glare layers according to embodiments. Concave-convex structures may be formed on the anti glare layers to scatter or irregularly reflect incident light. 
     Referring to  FIG. 19 , an anti glare layer  122  scatters or irregularly reflect light coming from a front filter  100  so that interference between light reflected from the front filter  100  and light reflected from a display module  140  can be prevented. 
     Therefore, although the distance (d) between the front filter  100  and a display panel of the display module  140  is 1.4 mm or smaller, Newton&#39;s rings may not appear owing to the anti glare layer  122  disposed on the front filter  100  (in detail, a glass  100  of the front filter  100 ). 
     That is, according to the embodiment, image quality deterioration caused by the image doubling phenomenon can be prevented by adjusting the distance (d) between the front filter  100  and the display panel of the display module  140  to 3 mm or smaller, and although the distance (d) is 1.4 mm or smaller, Newton&#39;s ring may not appear owing to the anti glare layer  122 . 
     Referring to  FIG. 20 , an anti glare layer  141  may be disposed on the front side of a display module  140 . In detail, the anti glare layer  141  may be disposed on a front plate of a display panel. In this case, the anti glare layer  141  scatters or irregularly reflects light incident on the display module  140  so that interference between light reflected from a front filter  100  and light reflected from the display module  140  can be reduced. 
     Referring to  FIG. 21 , an EMI shied layer  120  may be disposed on the rear side of a glass  110  of a front filter  100 , and an anti glare layer  122  may be disposed on the rear side of the EMI shied layer  120 . 
     Referring to  FIG. 22 , an EMI shied layer  120 , a protective layer  121  formed of a PET film, and an anti glare layer  122  may be stacked on the rear side of a glass  110  of a front filter  100 . 
       FIG. 23  is a sectional view illustrating a display apparatus according to another embodiment. 
     Referring to  FIG. 23 , the display apparatus of the current embodiment may include a front filter  41 , a back cover  42 , and a frame  46  disposed between the front filter  41  and the back cover  42 . The frame  46  forms a portion of the lateral side of the display apparatus. 
     A plurality of panel supporter  43  may be fixed to the front filter  41  and a shield part  411 . A module receiving part  412  may be disposed on the shield part  411  to receive a portion of a display module  44 . 
     A first fixing hole  431  may be formed in the panel supporter  43  for fixing the display module  44  and a connection member  45 , and a second fixing hole  432  may be formed in the panel supporter  43  to fix the back cover  42 . 
     The connection member  44  may include: a fixed part  451  fixed to the panel supporter  43 ; and a module supporter  452  bent from the cap plate  451  to support an edge of the display module  44 . 
     The fixing part  451  may include: a first fixing hole  453  through which a coupling member  471  is inserted; a second fixing hole  454  through which a coupling member  427  is inserted to fix the back cover  42  to the panel supporter  43 . 
     The frame  46  may include: first and second fixing holes  461  and  462  aligned with the first and second fixing holes  431  and  432  of the panel supporter  43 ; and an insertion hole  463  in which the panel supporter  43  is inserted. 
     An edge part  422  extending outward from a body part  421  of the back cover  42  is connected to the frame  46 , and fixing holes  423  formed in the edge part  422  are aligned with the second fixing holes  432 ,  462 , and  454 . The coupling member  472  coupled to the second fixing hole  432  of the panel supporter  43  may be inserted through the fixing holes  432 ,  462 , and  454 . 
     In the case of the display apparatus shown in  FIG. 23 , the distance (d) between a panel  441  and the front filter  41  may be adjusted to 3 mm or smaller for preventing the image doubling phenomenon and resulting image quality deterioration as described with reference to  FIGS. 2 and 3 . 
     In addition, if the distance (d) between the panel  441  and front filter  41  is 1.4 mm or smaller, an anti glare layer such as the anti glare layers  122  shown in  FIGS. 19 to 22  may be used to prevent generation of Newton&#39;s rings and resulting image quality deterioration. 
     Although embodiments have been described with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure. More particularly, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims. In addition to variations and modifications in the component parts and/or arrangements, alternative uses will also be apparent to those skilled in the art.
