     BACKGROUND 
     Field of the Invention 
     The present invention relates to a display device, and more particularly, to a display device with a minimized thickness and an enhanced aesthetic appearance. 
     Discussion of the Related Art 
     As society advances to the information-oriented society, display devices that display a massive amount of information are rapidly advancing. In particular, liquid crystal display (LCD) devices or organic light emitting display devices (which are flat panel display devices having excellent performance in terms of thinning, lightening, and low power consumption) are being practically applied. 
     In the LCD devices, active matrix LCD devices include an array substrate including a thin film transistor (TFT) that is a switching element for adjusting turn-on/off of a voltage for each pixel, and have an excellent ability to realize a resolution and a moving image. Therefore, the active matrix LCD devices are attracting much attention. 
     Moreover, the organic light emitting display devices are self-emitting devices that has a characteristic in which luminance is high and an operating voltage is low, and self-emits light. The organic light emitting display devices have a high contrast ratio (C/R), a thin thickness, low-temperature stability, and a low driving voltage, and have a response time of microsecond (μs), thereby easily displaying a moving image. Also, a driving circuit for the organic light emitting display devices is easily manufactured and designed. Therefore, the organic light emitting display devices are attracting much attention as flat panel display devices. 
     Various remedies are being needed in order for display devices to appeal to more consumers. Particularly, a thickness of a display device is minimized, and research is increasingly conducted on a design with an enhanced aesthetic appearance that can induce consumers to buy by appealing to the consumers&#39; sense of beauty. 
       FIG. 1  is a schematic cross-sectional view of a general display device. 
     As illustrated in  FIG. 1 , the general display device includes a display panel  10  including a lower substrate  12  and an upper substrate  14 , a panel driver  20 , and a top case  30 . 
     The lower substrate  12  includes a plurality of gate lines and a plurality of data lines which intersect with each other to define a plurality of pixel areas, a TFT formed in each of the plurality of pixel areas, and a pixel electrode connected to the TFT. 
     The upper substrate  14  includes a color filter, and is facing-coupled to the lower substrate  12 . A portion of the lower substrate  12  is exposed to the outside for applying signals to the gate lines and the data lines which are formed on the lower substrate  12 . To this end, a partial area of the lower substrate  12  is not coupled to the upper substrate  14 . The panel driver  20  is connected to a pad part formed at an edge of the lower substrate  12  which is not coupled to the upper substrate  14 , and transfer the signals to the gate lines and the data lines through the pad part. 
     The top case  30  is provided to cover a front edge and each side of the display panel  10 . The top case  30  is applied for preventing the panel driver  20 , connected to the pad part of the lower substrate  12 , from being exposed to the outside. 
     Since the top case  30  is provided to cover the front edge of the display panel  10  so as to prevent the panel driver  20  from being exposed, the general display device has the following problems. 
     First, since the top case  30  is provided on the upper substrate  14 , a thickness of the display device increases, and due to a step height between the top case  30  and the display panel  10 , a stepped portion is formed at a front surface of the display device. For this reason, a sense of beauty in design is reduced. 
     Second, a bezel width of the display device increases due to a front width of the top case  30  that prevents the panel driver  20  from being exposed, causing a reduction in a sense of beauty in design.

     Hereinafter, a display device according to embodiments of the present invention will be described in detail with reference to the accompanying drawings. 
       FIG. 2  is a view illustrating a display device according to a first embodiment of the present invention.  FIG. 3  is a cross-sectional view taken along line I-I′ of  FIG. 2 .  FIG. 4  is a cross-sectional view taken along line II-II′. 
     Referring to  FIGS. 2 to 4 , the display device according to the first embodiment of the present invention includes: a display panel  100  that includes a display area AA and a non-display area NA surrounding the display area AA; a backlight unit  200  that irradiates light onto the display panel  100 ; a panel driver  300  that is connected to the display panel  100  in the non-display area NA of the display panel  100 ; and a panel supporting part  400  that accommodates the backlight unit  200  and the panel driver  300 , and surrounds a rear surface and four sides of the display panel  100  without protruding to a front surface of the display panel  100 . 
     The display panel  100  includes an outer substrate  110 , an inner substrate  120 , a reflection reduction member  130 , an upper polarization member  140 , and a lower polarization member  150 . 
     The outer substrate  110  is a thin film transistor (TFT) array substrate, and includes the display area AA and the non-display area NA surrounding the display area AA. 
     The display area AA of the outer substrate  110  includes a plurality of pixels which are respectively formed in a plurality of pixel areas provided by intersections between a plurality of gate lines (not shown) and a plurality of data lines (not shown). Each of the plurality of pixels includes a TFT connected to a gate line and a data line, a pixel electrode connected to the TFT, and a common electrode that is formed adjacent to the pixel electrode and receives a common voltage. The common electrode may be formed on the inner substrate  120  instead of the outer substrate  110  depending on a driving mode of a liquid crystal layer. The outer substrate  110  generates an electric field corresponding to a difference voltage between the common voltage and a data voltage applied to each pixel to adjust a light transmittance of the liquid crystal layer. 
     The non-display area NA of the outer substrate  110  may be defined as an edge area of the outer substrate  110  which surrounds upper, lower, left, and right sides of the display area AA, and may include a pad part PP and a gate driving circuit (not shown). 
     The pad part may be provided at one side edge of the outer substrate  110 , and may include a plurality of pads that are connected to a plurality of signal lines, for example, a plurality of data lines, a plurality of gate control signal lines, and a plurality of power lines. 
     The gate driving circuit is provided at one side of short side or both non-display areas NA of the outer substrate  110  at the same time with a process of manufacturing the TFT of each pixel, connected to the plurality of gate lines formed in the display area AA, and connected to the pad part PP through the gate control signal lines. The gate driving circuit generates a gate signal (or a scan signal) according to a gate control signal which is supplied from the panel driver  300  through the pad part PP and the gate control signal line, and supplies the gate signal to a corresponding gate line. 
     The inner substrate  120  is a color filter array substrate, and is formed to have a relatively smaller area than that of the outer substrate  110 . The inner substrate  120  is facing-coupled to a bottom of the outer substrate  110  except the pad part PP of the outer substrate with the liquid crystal layer (not shown) therebetween by a substrate coupling member ( 115  in  FIG. 6 ). 
     The inner substrate  120  includes a light blocking layer (not shown), which is formed at an edge of the inner substrate  120  and defines a pixel area corresponding to each pixel formed on the outer substrate  110 , and a color filter layer (not shown) that is formed in each pixel. The light blocking layer may be formed on the inner substrate  120  so as to define the pixel area. However, a function of the light blocking may be performed by the reflection reduction member  130  formed on the outer substrate  110 , and thus, the light blocking layer may not be provided. The color filter layer filters light, which is incident from the backlight unit through the inner substrate  120  and the liquid crystal layer, to color light. 
     The reflection reduction member  130  reduces a reflectivity of external light by a metal line formed at an inner surface of the outer substrate  110 , and removes static electricity applied from the outside, thereby enhancing visual characteristic shown in the display panel  100  and preventing a quality of an image from being degraded due to the static electricity. For example, the reflection reduction member  130  may include a non-reflection conductive pattern that is formed of a conductive material on the outer substrate  110 , and overlaps at least one selected from a gate line and a data line so as to be connected to each other. For example, the non-reflection conductive pattern may be formed in a grid pattern form, in which the non-reflection conductive pattern overlaps the gate line, or a lattice pattern form in which the non-reflection conductive pattern overlaps the gate line and the data line. 
     The upper polarization member  140  is adhered to the outer substrate  110  so as to cover the reflection reduction member  130 . The upper polarization member  140  according to an embodiment may include a polarizing film which is adhered to a top of the outer substrate  110 , and polarizes light passing through the pixel area of the outer substrate  110 . The upper polarization member  140  according to another embodiment may include an upper polarizing film, which is adhered to the top of the outer substrate  110  and polarizes the light passing through the pixel area of the outer substrate  110 , and a retarder film which is adhered to the upper polarizing film, and separates a three-dimensional (3D) image (i.e., a left image and a right image), displayed by the display panel  100 , into different polarization states. 
     The lower polarizing member  150  may include a lower polarizing film that polarizes a light which is incident from the backlight unit  200  onto the inner substrate  120 . 
     The backlight unit  200  is accommodated in the panel supporting part  400 , and irradiates light onto the display panel  100 . To this end, the backlight unit  200  includes a light guide panel  210 , a light source  220 , a reflective sheet  230 , and an optical sheet member  240 . 
     The light guide panel  210  is formed in a flat (or wedge) shape, and travels light, which is incident through a light incident surface from the light source  220 , to the display panel  100 . 
     The light source  220  is disposed to face the light incident surface that is provided on at least one side of the light guide panel  210 , and irradiates the light onto the light guide panel  210 . In this case, the light source  220  may include a fluorescent lamp or a light emitting diode (LED). 
     The reflective sheet  230  is disposed at a bottom of the light guide panel  210 , and reflects the light, which is incident from the light guide panel  210 , to the display panel  100 . The reflective sheet  230  may be disposed to support the bottom of the light guide panel  210 , or may support the bottom of the light guide panel  210  and surround sides other than the light incident surface of the light guide panel  210 . 
     The optical sheet member  240  is disposed on the light guide panel  210 , and enhances a luminance characteristic of the light which travels from the light guide panel  210  to the display panel  100 . To this end, the optical sheet member  240  may include at least one diffusive sheet, which diffuses the light, and at least one prism sheet that collects the diffused light, or may include a complex functional sheet that simultaneously diffuses and collects the light. 
     The panel driver  300  is connected to the pad part PP which is provided on the outer substrate  110  of the display panel  100 , and allows a two-dimensional (2D) image based on a 2D display mode and a 3D image based on a 3D display mode to be displayed in the display area AA of the display panel  100 . For example, the panel driver  300  includes a plurality of flexible circuit films  310  connected to the pad part PP, a data driving integrated circuit (IC) mounted on each of the plurality of flexible circuit films  310 , a printed circuit board (PCB)  330  connected to the plurality of flexible circuit films  310 , and a driving circuit unit  340  mounted on the PCB  330 . 
     Each of the plurality of flexible circuit films  310  is adhered to the pad part PP and the PCB  330 , and may include a tape carrier package (TCP) or a chip on flexible board (or a chin on film (COF). Each of the plurality of flexible circuit films  310  is bent from the pad part PP, is accommodated in the panel supporting part  400 , and is not exposed to a front surface and sides of the pad part PP. In this case, each of the plurality of flexible circuit films  310  may be connected to the pad part PP by a reverse bonding process, for preventing the bent flexible circuit film  310  from protruding in a side direction of the outer substrate  110  or from contacting a side wall of the panel supporting part  400 . Here, according to the reverse bonding process, an end of the flexible circuit film  310  adhered to the pad part PP is adhered more adjacent to a side of the outer substrate  110  than a side of the inner substrate  120 , and a bending area of the flexible circuit film  310  is adhered more adjacent to the side of the inner substrate  120  than the side of the outer substrate  110 , whereby the flexible circuit film  310  is disposed apart from the outer substrate  110  in a direction from the side to the inside of the outer substrate  110 . In order to prevent a connection failure of the flexible circuit film  310  caused by penetration of water and foreign materials, an end of the flexible circuit film  310  adjacent to the side of the outer substrate  110  may be protected by a resin thin film  350 . 
     A first and/or last flexible circuit film(s)  310  of the plurality of flexible circuit films  310  supplies/supply the gate control signal, input from the driving circuit unit  340 , to corresponding pads of the pad part PP. 
     A data driving IC  320  is mounted on each of the plurality of flexible circuit films  310 . The data driving IC  320  converts digital image data, which is input through the PCB  330  from the driving circuit  340 , into a data voltage, and supplies the data voltage to a corresponding data line through the pad part PP. 
     The PCB  330  is electrically connected to other side of each of the plurality of flexible circuit films  310 , and transfers a signal, which is necessary for driving of the display panel  100 , to a corresponding flexible circuit film  310 . 
     The driving circuit part  340  is mounted on the PCB  330 , and drives the data driving IC  320  and the gate driving circuit. For example, the driving circuit unit  340  includes a timing controller (not shown) that controls driving of the data driving IC  320  and the gate driving circuit and supplies external digital image data to a corresponding data driving IC  320 , various power circuits (not shown), and a memory (not shown). 
     The panel supporting part  400  accommodates the backlight unit  200  and the panel driver  300 , and is coupled to a rear edge of the display panel  100  in order for an entire front surface of the display panel  100  to be exposed to the outside. To this end, the panel supporting part  400  includes a guide frame  410 , a panel coupling member  420 , a supporting case  430 , and an external cover  440 . 
     The guide frame  410  is formed in a tetragonal frame shape so as to support the rear edge of the display panel  100 , and is coupled to the rear edge of the display panel  100  by the panel coupling member  420 . For example, the guide frame  410  may include a panel coupling part  412  and a guide side wall  414 . The panel coupling part  412  is coupled to the rear edge of the display panel  110  by the panel coupling member  420 . The guide side wall  414  is vertically formed at an outer edge of the panel coupling part  412  so as to have a certain height, and supports the panel coupling part  412 . 
     The guide frame  410  may be divided into four or more sub-frames, and for example, may be configured with a plurality of sub-frames which are coupled to the display panel by the panel coupling member  420 . 
     The panel coupling member  420  is provided at the panel coupling part  412  of the guide frame  410 , and connects the display panel  100  to the guide frame  410 . In this case, the panel coupling member  420  may be coupled to the inner substrate  120  of the display panel  100  in consideration of a coupling force and thicknesses of the guide frame  410  and the display panel  100 , but is not limited thereto. For example, the panel coupling member  420  may be coupled to the lower polarization member  150 . The panel coupling member  420  may be formed of a double-sided tape, a heat-hardening adhesive, or a photocurable adhesive. 
     The supporting case  430  is formed in a U-shape to have an accommodating space. The supporting case  430  supports (or accommodates) the backlight unit  200 , and supports the guide frame  410 . For example, the supporting case  430  may include a supporting plate  432  and a supporting side wall  434 . The supporting plate  432  is formed in a flat shape so as to cover a rear surface of the display panel  100 , and supports the backlight unit  200 . The supporting side wall  434  is vertically formed at an edge of the supporting plate  432 , allows an accommodating space to be provided on the supporting plate  432 , and supports the panel coupling part  412  of the guide frame  410 . Optionally, the supporting case  430  may not be provided for designing, lightening, and slimming of the display device. 
     The external cover  440  accommodates the supporting case  430 , and surrounds the guide frame  410  and the side of the display panel  100  in order for the entire front surface of the display panel  100  to be exposed. The external cover  440  may be formed of a plastic material or a metal material, but may be formed of a metal material for enhancing an aesthetic appearance of a manufactured display device and/or a discharging path of static electricity applied to the display panel  100 . For example, the external cover  440  includes a rear cover  442  and a side cover  444 . 
     The rear cover  442  configures the outermost rear surface of the manufactured display device, and supports the supporting case  430 . For example, the rear cover  442  may be coupled to the supporting case  430  by a coupling (or bonding) method using a screw. Optionally, when the supporting case  430  is not provided, the rear cover  442  supports the backlight unit  200 . 
     The side cover  444  configures the outermost side of the manufactured display device, and is formed vertically from an edge of the rear cover  442  to surround the guide frame  410  and the side of the display panel  100 . In this case, a height of the side cover  444  is set so that a top of the side cover  444  does not protrude onto the display panel, and more particularly, a front surface of the upper polarization member  140 . The side cover  444  may be coupled to a guide side wall  414  of the guide frame  410  by a coupling (or bonding) method using a hook, a screw, or a rail using a groove and a projection. 
     The display device according to the first embodiment of the present invention may further include an edge sealing member  500  that protects each side of the display panel  100 , and discharges static electricity, applied to the display panel  100 , to the panel supporting part  400 . 
     The edge sealing member  500  is provided at each side of the display panel  100 . For example, the edge sealing member  500  is provided at sides other than a lower side of the display panel  100  (in which the pad part PP is provided) so as to cover a portion of a side of the upper polarization member  140 , a portion of a side of the inner substrate  120 , an entire side of the outer substrate  110 , and an entire side of the reflection reduction member  130 . In addition, the edge sealing member  500  is provided at the lower side of the display panel  100  (in which the pad part PP is provided) so as to cover a portion of the side of the upper polarization member  140 , an entire side of the reflection reduction member  130 , and a portion of the side of the outer substrate  110 . 
     An upper corner of each side of the outer substrate  110  and each side of the reflection reduction member  130  have a first inclined plane IP 1  having a first slope, for increasing an adhesive area between the edge sealing member  500  and the display panel  100  and preventing the edge sealing member  500  from being stripped. Each side of the upper polarization member  140  has a second inclined plane IP 2 , which is separated by a certain distance from the first inclined plane IP 1  and has a second slope which is the same as or different from the first slope, for exposing a top edge of the reflection reduction member  130  so as to increase an electrical connection area between the edge sealing member  500  and the reflection reduction member  130  and to prevent the upper polarization member  140  from being stripped. Here, a light blocking material may be formed at the first inclined plane IP 1 , for preventing a side light leakage of the display panel  100  caused by the total internal reflection of the inner substrate  120 . 
     The edge sealing member  500 , as illustrated in  FIG. 5 , is electrically connected to a top edge (i.e., a portion between the first and second inclined planes) of the reflection reduction member  130  (which is not covered by the upper polarization member  140 ) and an entire side of the reflection reduction member  130 , and electrically and physically contacts the side cover  444  of the external cover  440 , thereby discharging static electricity SE, applied to the reflection reduction member  130 , to the panel supporting part  400  (more particularly, the side cover  444  of the external cover  440 ). 
     The edge sealing member  500  may be formed of a mixing material of a conductive member and an adhesive material such as a silicon-based or ultraviolet (UV)-hardening sealant (or a resin). For example, the conductive member may be a conductive ball, a particle, or a nanowire, and may be formed of a conductive material such as gold (Au), silver (Ag), or copper (Cu). Also, the edge sealing member  500  may include a colored resin or a light blocking resin, for preventing a side light leakage of the display panel  100  caused by the total internal reflection of the inner substrate  120 . 
       FIG. 6  is a cross-sectional view for describing the reflection reduction member of  FIGS. 3 and 4 . 
     Referring to  FIG. 6 , the reflection reduction member  130  according to an embodiment of the present invention includes a non-reflective conductive pattern  132  which is formed at a top of the outer substrate  110  so as to overlap a metal line ML formed at the inner surface of the outer substrate  110 . 
     The non-reflective conductive pattern  132  may be formed of a conductive metal material, and particularly, may be formed in a stacked structure having two or more layers including an oxide layer  132   a  and a metal layer  132   b , for reducing reflectivity. For example, the non-reflective conductive pattern  132  may be formed in a two-layer structure having the oxide layer  132   a  and the metal layer  132   b . As another example, the non-reflective conductive pattern  132  may be formed in a three-layer structure having a first metal layer, an oxide layer, and a second metal layer, in which case the first and second metal layers may be formed of the same material or different materials. As another example, the non-reflective conductive pattern  132  may be formed in a three-layer structure having a first oxide layer, a metal layer, and a second oxide layer, in which case the first and second oxide layers may be formed of the same material or different materials. In the non-reflective conductive layer  132 , the oxide layer  132   a  may include Zn, In, or Sn-based oxide, and the metal layer  132   b  may include one selected from Cu, Mo, Ti, Mo/Ti, and Cr. 
     The non-reflective conductive pattern  132  may have black or a chromatic color depending on a metal material and a stacked structure. For example, when the non-reflective conductive pattern  132  is formed in a two-layer structure having the metal layer of Mo/Ti and the oxide layer  132   a  of indium tin oxide (ITO), the non-reflective conductive pattern  132  may have deep blue. As another example, when the non-reflective conductive pattern  132  has a three-layer structure including a first metal layer of Cu, an oxide layer of ITO, and a second metal layer of Mo/Ti, the non-reflective conductive pattern  132  may have black. As described above, when the non-reflective conductive pattern  132  has a color, an entire edge of the display device has a specific color, thereby enhancing an aesthetic design of the display device. 
     Each of four sides of the non-reflective conductive pattern  132  may be formed to have the same third inclined plane IP 3  as the first inclined plane IP 1  by using a chamfer process of forming the first inclined plane IP 1  at a top corner of the outer substrate  110 . 
     The non-reflective conductive pattern  132  according to an embodiment, as illustrated in  FIG. 7A , may be formed at a top of the outer substrate  110  so as to overlap with a gate line which is formed at the inner surface of the outer substrate  110 . That is, the non-reflective conductive pattern  132  according to an embodiment includes: first to fourth conductive border patterns  132 _E 1 ,  132 _E 2 ,  132 _E 3  and  132 _E 4  which are formed in a tetragonal frame shape so as to respectively overlap upper, lower, left, and right non-display areas corresponding to an edge of the outer substrate  110 ; and a plurality of conductive line patterns  132 _L which are formed in a grid pattern form in a display area except a pixel area PA so as to overlap with the gate line. In this case, each of the plurality of conductive line patterns  132 _L is connected, in a grid pattern form, between the first and second conductive border patterns  132 _E 1  and  132 _E 2  (which are parallel to each other) with the display area therebetween. 
     The non-reflective conductive pattern  132  according to another embodiment, as illustrated in  FIG. 7B , may be formed at the top of the outer substrate  110  so as to overlap a gate line and a data line which are formed at the inner surface of the outer substrate  110 . That is, the non-reflective conductive pattern  132  according to an embodiment includes: first to fourth conductive border patterns  132 _E 1 ,  132 _E 2 ,  132 _E 3  and  132 _E 4  which are formed in a tetragonal frame shape so as to respectively overlap the upper, lower, left, and right non-display areas corresponding to the edge of the outer substrate  110 ; and a plurality of conductive lattice patterns  132 _G which are formed in a lattice pattern form in the display area except the pixel area PA so as to overlap the gate line and the data line. In this case, each of the plurality of conductive lattice patterns  132 _G is connected, in a lattice pattern form, to the first to fourth conductive border patterns  132 _E 1 ,  132 _E 2 ,  132 _E 3  and  132 _E 4  which surround the display area. 
     In the non-reflective conductive pattern  132  according to an embodiment and the non-reflective conductive pattern  132  according to another embodiment, the first conductive border pattern  132 _E 1  may overlap an upper non-display area of the outer substrate  110 , the second conductive border pattern  132 _E 2  may overlap a lower non-display area of the outer substrate  110 , the third conductive border pattern  132 _E 3  may overlap a left non-display area of the outer substrate  110 , and the fourth conductive border pattern  132 _E 4  may overlap a right non-display area of the outer substrate  110 . In this case, the second conductive border pattern  132 _E 2  may overlap the pad part PP which is provided on the outer substrate  110 , and the third and fourth conductive border patterns  132 _E 3  and  132 _E 4  may overlap the gate driving circuit which is provided on the outer substrate  110 . 
     The reflection reduction member  130  according to an embodiment of the present invention may further include a protective layer  134  that is formed on the outer substrate  110  to protect the non-reflective conductive pattern  132 . 
     The protective layer  134  prevents the non-reflective conductive pattern  132  from being damaged by a substrate manufacturing process that forms a TFT array (or a pixel array), connected to a gate line and a data line, on a bottom of the outer substrate  110 . That is, when the TFT array is formed on the bottom of the outer substrate  110  and then the reflection reduction member  130  is formed on a top of the outer substrate  110 , the TFT array can be damaged by a manufacturing process of forming the reflection reduction member  130 . In order to prevent the TFT array from being damaged, the reflection reduction member  130  is first formed on the top of the outer substrate  110 , and then, the TFT array is formed on the bottom of the outer substrate  110 . Therefore, in a TFT array manufacturing process, the reflection reduction member  130  contacts a substrate transferring member or a substrate supporting member in a process of transferring or supporting the outer substrate  110 , and thus, the protective layer  134  is applied for preventing the reflection reduction member  130  from being damaged due to the contact. 
     The protective layer  134  according to an embodiment may be formed of a material having hardness of 9H or more. For example, the protective layer  134  may be formed of SiNx. 
     Four sides of the protective layer  134  may be formed to be separated from the first inclined IP 1  by a certain distance in order for a top edge of the reflection reduction member  130  to be coupled to the edge sealing member  500 . Furthermore, the upper polarization member  140  is adhered to an entire front surface of the protective layer  134 . In this case, the four sides of the protective layer  134  may be separated from the first inclined plane IP 1  by a certain distance using a cutting process (for example, a laser cutting process) of forming the second inclined plane IP 2  at four sides of the upper polarization member  140 , and may have a fourth inclined plane IP 4  having a fourth slope that is the same as or different from the second slope. 
     In the display device according to the first embodiment of the present invention, since the entire front surface of the outer substrate  110  is exposed to the outside, and the panel driver  400  is adhered to the bottom of the outer substrate  110  and exposed to the outside, a separate external cover for covering the panel driver  400  is not needed. Therefore, according to an embodiment of the present invention, a thickness of the display device, and a front step height of the display device is removed, thereby obtaining an aesthetic design effect in which the front surface of the display device is recognized as one structure. Furthermore, according to an embodiment of the present invention, a bezel configuring a border of the display device can be fully removed, or even when the bezel is formed an aesthetic appearance of the display device can be enhanced compared to a related art display device since the width of the bezel is very small. 
     Moreover, according to an embodiment of the present invention, since the reflection reduction member  130  is formed of a conductive material on the outer substrate  110  so as to be connected to each other, a reflectivity of external light by the metal line formed on the outer substrate  110  is reduced, and static electricity applied from the outside is removed. Accordingly, visual characteristic which is shown in the display panel can be enhanced, and a quality of an image can be prevented from being degraded due to an inflow of static electricity. 
       FIG. 8  is a cross-sectional view illustrating a display panel in a display device according to a second embodiment of the present invention, and illustrates that an electricity removing layer is additionally formed on an outer substrate. In describing the second embodiment of the present invention, the same elements as those of the display device according to the first embodiment are not described. Hereinafter, only the electricity removing layer will be described. 
     An electricity removing layer  640  according to an embodiment may be formed of a material, having high heat resistance, transparency, corrosion resistance which does not react with an etchant of a metal line, and stiffness, on the outer substrate  110  so as to cover the reflection reduction member  130  formed at the top of the outer substrate  110 , for removing static electricity applied from the outside to the inside of the display panel  100 . The electricity removing layer  640  according to an embodiment may have electrical conductivity of 10 9  Ω/sq or less, for easily removal of static electricity, and as described above, the electricity removing layer  640  may have hardness of 8H or more, for preventing the reflection reduction member  130  from being damaged by a physical contact which occurs in a process of manufacturing a TFT array. For example, the electricity removing layer  640  may be formed of a transparent metal oxide material, a transparent organic conductive material, or indium gallium zinc oxide (IGZO). Here, examples of the electricity removing layer formed of a transparent organic conductive material may include a graphene-polymer composite layer, a graphene-metal particle layer, or an organic transparent conductive layer. 
     The reflection reduction member  130  may include the non-reflective conductive pattern  132 , or include the non-reflective conductive pattern  132  and the protective layer  134 . Therefore, the electricity removing layer  640  according to an embodiment may be formed on the outer substrate  110  so as to cover the reflection reduction member  130  including only the non-reflective conductive pattern  132 , or may be formed on the outer substrate  110  so as to cover the protective layer  134  of the reflection reduction member  130 . 
     The electricity removing layer  640  according to another embodiment, as illustrated in  FIG. 9 , may be formed on the outer substrate  110  so as to cover the reflection reduction member  130  formed on the top of the outer substrate  110 , and may be formed of a multilayer including a transparent conductive layer  642  and a protective layer  644 . 
     The transparent conductive layer  642  may be formed on the outer substrate  110  so as to cover the reflection reduction member  130  including only the non-reflective conductive pattern  132 , and may be formed of Zn, In, or Sn-based oxide. The transparent conductive layer  642  may protect the non-reflective conductive pattern  132 , and remove static electricity applied from the outside to the outer substrate  110 . 
     The protective layer  644  may be formed on the outer substrate so as to cover the transparent conductive layer  642 , and as described above, the protective layer  644  may have hardness of 8H or more, for protecting the transparent conductive layer  642  and preventing the reflection reduction member  130  from being damaged by a physical contact which occurs in a process of manufacturing a TFT array. For example, the protective layer  644  may be formed of SiNx. 
     Four sides of the electricity removing layer  640  according to an embodiment and another embodiment may be formed to be separated from the first inclined IP 1  or the third inclined IP 3  by a certain distance in order for a top edge of the reflection reduction member  130  to be coupled to the edge sealing member  500 . Furthermore, the upper polarization member  140  is adhered to an entire front surface of the electricity removing layer  640 . In this case, the four sides of the electricity removing layer  640  may be separated from the first inclined plane IP 1  by a certain distance in a cutting process (for example, a laser cutting process) of forming the second inclined plane IP 2  at four sides of the upper polarization member  140 , and may have the fourth inclined plane IP 4  having a fourth slope that is the same as or different from the second slope. 
     The electricity removing layer  640  according to an embodiment is formed on the outer substrate  110  so as to cover the reflection reduction member  130 , is electrically and directly connected to the edge sealing member  500 , and is electrically connected to the edge sealing member  500  through the top edge of the reflection reduction member  130 , thereby discharging static electricity, applied from the outside, to the panel supporting part  400  through the edge sealing member  500 . Accordingly, a quality of an image can be prevented from being degraded due to static electricity. 
       FIG. 10  is a cross-sectional view illustrating a display panel in a display device according to a third embodiment of the present invention, and illustrates that unlike the display device according to the second embodiment of the present invention, a reflection reduction member  730  is formed on the inner surface of the outer substrate  110 , and an electricity removing layer  740  is formed on the top of the outer substrate  110 . In describing the third embodiment of the present invention, the same elements as those of the display device according to the preceding embodiments are not described. Hereinafter, only the reflection reduction member  730  and the electricity removing layer  740  will be described. 
     The reflection reduction member  730  according to an embodiment includes a non-conductive pattern which is formed between a gate line GL and the inner surface of the outer substrate, and minimizes or prevents reflection of external light (which passes through the outer substrate  110 ) by the gate line GL. In this case, the non-conductive pattern may be formed of a non-conductive material. For example, the non-conductive material may be a black material, polyamide, or a light-absorbing material. Here, the light-absorbing material may contain amorphous silicon (a-Si). Generally, since a-Si has high light absorptivity, a-Si is used to convert solar energy into electrical energy, and has about 100 times higher light absorptivity than that of crystalline silicon. 
     The reflection reduction member  730  according to an embodiment may be additionally formed between a data line DL and the inner surface of the outer substrate  110 , for minimizing or preventing reflection of external light by the data line DL. In this case, a gate insulating layer  113  is formed between the reflection reduction member  730  and the data line. 
     The electricity removing layer  740  may be formed of a transparent metal oxide material, a transparent organic conductive material, or indium gallium zinc oxide (IGZO) on the entire front surface of the outer substrate  110 , or may be formed of a multilayer including a transparent conductive layer and a protective layer. Here, an example of a material forming the electricity removing layer  740  may include a black pigment or a colored pigment. 
     Four sides of the electricity removing layer  740  may be formed to have a fifth inclined plane IP 5  having a fifth slope, which is the same as and different from the first slope, by using a chamfer process of forming the first inclined plane IP 1  at each of upper corners of the outer substrate  110 . Furthermore, the upper polarization member  140  is adhered to an entire front surface of the electricity removing layer  740 . In this case, in order to prevent the upper polarization member  140  from being stripped, the four sides of the upper polarization member  140  may be separated from the first inclined plane IP 1  by a certain distance in a cutting process (for example, a laser cutting process) of forming the second inclined plane IP 2  at the four sides of the upper polarization member  140 . Therefore, an upper edge of the electricity removing layer  740  is exposed to the outside by the fifth inclined plane IP 5  of the upper polarization member  140  which is separated from the first inclined plane IP 1  of the outer substrate  110 , and covered by the edge sealing member  500 , and thus, the four sides and upper edge of the electricity removing layer  740  are electrically connected to the edge sealing member  500 . 
     The display device according to the third embodiment of the present invention can obtain the same aesthetic design effect as that of the display devices according to the first and second embodiments of the present invention. According to the third embodiment, the reflection reduction member  730  is formed between the outer substrate  110  and the metal line, and the electricity removing layer  740  is formed on the front surface of the outer substrate  110 . Therefore, a reflectivity of external light by the metal line formed on the outer substrate  110  is reduced, and static electricity applied from the outside is removed. Accordingly, visual characteristic shown in the display panel  100  can be enhanced, and a quality of an image can be prevented from being degraded due to an inflow of static electricity. 
       FIG. 11  is a cross-sectional view illustrating a display panel in a display device according to a fourth embodiment of the present invention, and illustrates that unlike the display device according to the third embodiment of the present invention, a reflection reduction member  830  is formed of a low-reflection metal material, and a blocking layer  111  is additionally formed between a gate line GL and the reflection reduction member  830  formed of the low-reflection metal material. In describing the fourth embodiment of the present invention, the elements same as those of the display device according to the third embodiment are not described. Hereinafter, only the reflection reduction member  830  and the blocking layer  111  will be described. 
     The reflection reduction member  830  includes a conductive pattern. In this case, the conductive pattern may be formed of a conductive metal material, and particularly, may be formed in a stacked structure having two or more layers including an oxide layer  832  and a metal layer  834 , for reducing reflectivity. For example, the reflection reduction member  830  may be formed in a two-layer structure having the oxide layer  832  and the metal layer  834 . As another example, the reflection reduction member  830  may be formed in a three-layer structure having a first metal layer, an oxide layer, and a second metal layer, in which case the first and second metal layers may be formed of the same material or different materials. As another example, the reflection reduction member  830  may be formed in a three-layer structure having a first oxide layer, a metal layer, and a second oxide layer, in which case the first and second oxide layers may be formed of the same material or different materials. In the reflection reduction member  830 , the oxide layer  832  may include Zn, In, or Sn-based oxide, and the metal layer  834  may include one selected from Cu, Mo, Ti, Mo/Ti, and Cr. 
     The blocking layer  111  is formed on the inner surface of the outer substrate  110  so as to cover the reflection reduction member  830  formed on the inner surface of the outer substrate  110 , and electrically insulates the gate line GL from the reflection reduction member  830 . The blocking layer  111  may be formed of an insulating material. For example, the blocking layer  111  may be formed of SiNx to have a thickness of 0.1 um to 0.5 um. As another example, the blocking layer  111  may be formed of a high heat-resistant organic material or an organic material containing a pigment/dye, and an example of the organic material may include a siloxane-based or polyimide-based material. The blocking layer  111  performs a function of a planarizing layer that planarizes the inner surface of the outer substrate  110  in which the reflection reduction member  830  is formed. 
       FIG. 12  is a cross-sectional view illustrating a display panel in a display device according to a fifth embodiment of the present invention, and illustrates that unlike the display device according to the second embodiment of the present invention, a reflection reduction member  930  is formed of a semitransparent material, and a gate line GL having a two-layer structure is formed on the reflection reduction member  930 . In describing the fifth embodiment of the present invention, the same elements as those of the display device according to the first embodiment are not described. Hereinafter, only the reflection reduction member  930  and the gate line GL will be described. 
     The reflection reduction member  930  is formed between the gate line GL and the inner surface of the outer substrate  110 , and minimizes or prevents reflection of external light by the gate line GL passing the outer substrate  110  through destructive interference of light. The reflection reduction member  930  may be formed of one selected from indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), IGZO, aluminum zinc oxide (AZO), In 2 O 3 , Ga 2 O 3 —In 2 O 3 , ZnO:B, and ZnO—In 2 O 3 . 
     The gate line GL may be formed of a low-resistance metal material, and for example, may be formed of first and second metal layers M 1  and M 2  selected from Al, AlNd, Cu, copper alloy, CuNd, Mo, molybdenum alloy, and MoTi. For example, the first metal layer M 1  may be formed of Mo/Ti on the reflection reduction member  930 , and the second metal layer M 2  may be formed of Cu. 
     According to the fifth embodiment of the present invention, as illustrated in  FIG. 13 , some of external light EL incident on the outer substrate  110  is reflected as first reflection light RL 1  by the reflection reduction member  930 , and the other of the external light EL which passes through the reflection reduction member  930  without being reflected by the reflection reduction member  930  passes through the reflection reduction member  930 , and is reflected as second reflection light RL 2  by the first metal layer M 1 . However, the first and second reflection lights RL 1  and RL 2  are dissipated through destructive interference. To this end, a thickness of the reflection reduction member  930  is set so that the first and second reflection lights RL 1  and RL 2  are dissipated by destructive interference caused by a phase difference therebetween. 
       FIG. 14  is a cross-sectional view illustrating a display panel in a display device according to a sixth embodiment of the present invention, and illustrates that unlike the display devices according to the third to fifth embodiments of the present invention, the electricity removing layer  140  is formed on an upper polarization member  940 . In describing the sixth embodiment of the present invention, the same elements as those of the display devices according to the third to fifth embodiments are not described. Hereinafter, only the upper polarization member  940  will be described. 
     In the display devices according to the third to fifth embodiments, the electricity removing layer  140  for removing static electricity applied from the outside to the display panel is formed on the top of the outer substrate  110 . However, according to the sixth embodiment of the present invention, the electricity removing layer  140  is not formed on the top of the outer substrate  110  but is formed at the upper polarization member  940 . 
     The upper polarization member  940  may include an electricity removing film  942 , a lower protective film  944 , a polarizing film  946 , and an upper protective film  948 . 
     The electricity removing film  942  includes an electricity removing layer formed of a transparent conductive material, which may be arsenic (As). However, the present embodiment is not limited thereto. 
     The lower protective film  944  and the upper protective film  948  are formed with the polarizing film  946  therebetween, and protects the polarizing film  946 . 
     The polarizing film  946  includes a polarizer that polarizes incident light. A poly vinyl alcohol film is dyed with iodine, and is drawn in a specific direction, thereby forming the polarizing film  946 . The polarizing film  946  absorbs light which is incident in a drawn direction, but transmits light which is incident in a direction vertical to the drawn direction, thereby polarizing substantially incident light. 
     The upper polarization member  940  is adhered to the front surface of the outer substrate  110  through an adhesive layer  941  which is formed at a bottom of the electricity removing film  942 . 
     Four sides of the upper polarization member  940  may be formed to have a sixth inclined plane IP 6  having the same slope as that of the first inclined plane IP 1  by using a chamfer process of forming the first inclined plane IP 1  at each of corners of the outer substrate  110 . Therefore, the electricity removing layer of the upper polarization member  940  according to an embodiment is electrically connected to the edge sealing member  500  that covers a portion of the sixth inclined plane IP 6 . 
       FIG. 15  is a cross-sectional view illustrating a display panel and an external cover in a display device according to a seventh embodiment of the present invention, and illustrates that unlike the display devices according to the first to fifth embodiments of the present invention, a conductive strap  1100  is additionally formed. In describing the seventh embodiment of the present invention, the elements same as those of the display devices according to the first to fifth embodiments are not described. Hereinafter, only the conductive strap  1100  will be described. 
     In the display devices according to the first and second embodiments of the present invention, the conductive strap  1100  according to an embodiment is provided as at least one on each side of the outer substrate  110 , and electrically connects the non-reflective conductive pattern  132  of the reflection reduction member  140  to the side cover  444  of the external cover  440 . In this case, one side of the conductive strap  1100  may be adhered to the non-reflective conductive pattern  132  exposed at the upper edge of the outer substrate  110 , and the other of the conductive strap  1100  may pass through a lower portion of the edge sealing member  500 , and may be adhered to an inner surface of the side cover  444  by a conductive coupling member  1200 . 
     In the display devices according to the third to fifth embodiments of the present invention, the conductive strap  1100  according to another embodiment is provided as at least one on each side of the outer substrate  110 , and electrically connects the electricity removing layer  640  ( 740 ) to the side cover  444  of the external cover  440 . In this case, one side of the conductive strap  1100  may be adhered to the the electricity removing layer  640  ( 740 ) exposed at the upper edge of the outer substrate  110 , and the other of the conductive strap  1100  may pass through the lower portion of the edge sealing member  500 , and may be adhered to the inner surface of the side cover  444  by the conductive coupling member  1200 . 
     The conductive coupling member  1200  may be a double-sided tape formed of a metal material, or may be a screw that directly connects the other side of the conductive strap  1100  to the inner surface of the side cover  444 . 
     According to the seventh embodiment of the present invention, since the non-reflective conductive pattern  132  or electricity removing layer  640  ( 740 ) of the reflection reduction member  140  is electrically connected to the external cover  440  through the conductive strap  1100 , the edge sealing member  500  may be formed of an adhesive material such as a silicon-based or UV-hardening sealant (or resin) without a conductive member, but considering a tack time, the edge sealing member  500  may be formed of a UV-hardening sealant. Also, the edge sealing member  500  may be colorless (or transparent) or colored (for example, blue, red, bluish green, or black), but is not limited thereto. A color of the edge sealing member  500  may be selected depending on a design of the display device, and in order to prevent a side light leakage of the display panel by the total internal reflection of the inner substrate  120 , the edge sealing member  500  may be formed of a colored resin or a light blocking resin. When the edge sealing member  500  does not include a conductive member, the edge sealing member  500  may not contact the side cover  444  of the external cover  440 . 
     Hereinabove, the LCD device has been mainly described as an example, but the display device according to the embodiments of the present invention is not limited to the LCD device. Examples of the display device according to the embodiments of the present invention may include various flat panel display devices such as organic light emitting display devices. For example, when the display device is an organic light emitting display device, an encapsulating substrate (not shown) instead of the inner substrate  120  is coupled to the bottom of the outer substrate  110 , and the encapsulating substrate (not shown) does not include a color filter layer and a black matrix. The encapsulating substrate (not shown) may be formed of an opaque material such as aluminum foil or stainless steel in addition to transparent plastic or glass. Since the organic light emitting display device is a self-emitting device, the organic light emitting display device does not include the backlight unit  200 . 
     The display device according to the embodiments of the present invention may be applied to notebook computers, tablet computers, and various portable information devices, in addition to televisions and monitors. 
     As described above, since the entire front surface of the outer substrate is exposed to the outside and the panel driver is adhered to the bottom of the outer substrate and exposed to the outside, a separate external cover for covering the panel driver is not needed. Therefore, a thickness of the display device is reduced, and a front step height of the display device is removed, thereby obtaining an aesthetic design effect in which the front surface of the display device is recognized as one structure. 
     Moreover, a bezel configuring the border of the display device can be fully removed, or although the bezel is formed, since a width of the bezel is very small, an aesthetic appearance of the display device can be enhanced compared to a related art display device. 
     Moreover, the reflection reduction member is formed on the outer substrate, and thus, a reflectivity of external light by the metal line (which is formed on the outer substrate) is reduced, thereby enhancing visual characteristic which is shown in the display panel. 
     Moreover, the electricity removing layer is formed on the outer substrate along with the reflection reduction member, and thus reduces a reflectivity of external light and removes static electricity applied from the outside. Accordingly, visual characteristic which is shown in the display panel can be enhanced, and a quality of an image can be prevented from being degraded due to an inflow of static electricity. 
     It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
