However, the present invention is not limited thereto, A chip on glass (COG) structure may be formed.

Hereinafter, a display device according to various embodiments of the present invention capable of reducing a width of a bezel will be described in detail with reference to a sectional structure thereof.

3 is a schematic cross-sectional view of a display device according to an embodiment of the present invention, which corresponds to a cross section of the line I-I in FIG. 3 corresponds to a cross section from one side to the other side of the display device in which the panel driver 400 is not formed.

3, the display device according to an exemplary embodiment of the present invention includes a display panel 100, a light shielding member 150, a backlight unit 200, and a supporting structure 300.

The display panel 100 includes a first substrate 110, a second substrate 120, a first polarizer 130, and a second polarizer 140. The display panel 110 may include a liquid crystal panel. In this case, a liquid crystal layer sealed by a sealant may be interposed between the first substrate 110 and the second substrate 120 .

Although not shown, a black matrix is formed on the lower surface of the first substrate 110 to prevent light from leaking to regions other than the pixel region, and red, green, and blue A filter is formed, and an overcoat layer for substrate planarization may be formed on the lower surface of the color filter.

A gate line and a data line are formed on the upper surface of the second substrate 120 so as to define a pixel region, and a thin film transistor is formed as a switching element in a region where the gate line and the data line cross each other. And a pixel electrode connected to the thin film transistor may be formed in each of the pixel regions.

The specific configurations of the first substrate 110 and the second substrate 120 may be a driving mode of a liquid crystal panel such as TN (Twisted Nematic) mode, VA (Vertical Alignment) mode, IPS , A Fringe field switching (FFS) mode, and the like.

The first polarizer 130 is formed on the upper surface of the first substrate 110 and the second polarizer 140 is formed on the lower surface of the second substrate 120.

The first polarizing plate 130 has a transmission axis in a predetermined direction and the second polarizing plate 140 has a transmission axis in a direction different from the first polarizing plate 130. For example, the transmission axis of the first polarizer 130 and the transmission axis of the second polarizer 140 may form an angle of 90 degrees.

The second polarizer 140 transmits only light of a predetermined polarized light among the lights supplied from the backlight unit 200. The first polarizer 130 transmits light or absorbs light according to the alignment state of the liquid crystal layer between the first substrate 110 and the second substrate 120. That is, when the polarized light having passed through the second polarizing plate 140 passes through the liquid crystal layer and there is no change in the polarized light, the first polarizing plate 130 is not transmitted and the image becomes black, In the case where there is a change, the image may be in a white state while being transmitted through the first polarizer 130.

The light shielding member 150 is formed on a side surface of the display panel 100 to prevent light from leaking to an edge region of the display panel 100. That is, the light shielding member 150 blocks light from being transmitted to the side surface of the display panel 100. Accordingly, the light shielding member 150 is formed on the side surface of the first substrate 110 and the side surface of the second substrate 120. The light shielding member 150 is also formed on the side surface of the first polarizer 130 and the side surface of the second polarizer 140 so that light leaks from the side surface of the display panel 100 .

The light blocking member 150 includes a first light blocking member 151 and a second light blocking member 152. The first light blocking member 151 is in contact with a side surface of the display panel 100, a side surface of the first polarizing plate 130 and a side surface of the second polarizing plate 140, And is formed on the first light blocking member 151. The first light blocking member 150 and the second light blocking member 152 may have the same length.

The first light blocking member 151 is made of a polarizing sheet having a transmission axis in the first direction and the second light blocking member 152 is made of a polarizing sheet having a transmission axis in the second direction. At this time, the transmission axis in the first direction and the transmission axis in the second direction are different from each other, for example, at an angle of 90 degrees with respect to each other. Therefore, the light polarized while passing through the first light shielding member 151 can not pass through the second light shielding member 152, and the light passing through the display panel 100 and incident on the light shielding member 150 The light shielding member 150 can not transmit the light.

In particular, since the light incident on the light blocking member 150 is polarized light having passed through the second polarizing plate 140, the polarized light having passed through the second polarizing plate 140 is incident on the first light blocking member 140, The transmission axis of the light blocking member 151 is different from the transmission axis of the second polarizing plate 140, so that the light blocking effect of the light blocking member 150 can be improved. In this case, the transmission axis of the first light blocking member 151 may be set to be the same as the transmission axis of the first polarizing plate 130, and the transmission axis of the second light blocking member 152 may be set to be the same as the transmission axis of the second polarizing plate 140. [ As shown in FIG. The transmission axis of the first light blocking member 151 may be set to be the same as the transmission axis of the second polarizing plate 140 and the transmission axis of the second light blocking member 152 may be set to be the same as the transmission axis of the second polarizing plate 140. [ May be set to be the same as the transmission axis of the first polarizer 130.

On the other hand, although not shown, the light shielding member 150 is not limited to the two polarizing sheets having different polarizations, but may be a combination of three or more polarizing sheets.

As described above, according to the embodiment of the present invention, light is prevented from being transmitted to the side surface of the display panel 100 by the light shielding member 150 and light is leaked to the edge area of the display panel 100 Can be prevented. Therefore, in order to cover the edge area of the display panel 100, the upper case (reference numeral 35 in FIG. 1) is formed on the upper edge of the display panel 100, or a black matrix for preventing light leakage is additionally provided So that the bezel width of the display device can be reduced.

In addition, according to the embodiment of the present invention, it is not necessary to form the upper case (reference numeral 35 in FIG. 1) on the upper edge of the display panel 100 or further form a black matrix for preventing light leakage , The upper surface of the display panel 100 may be exposed to the outside to enhance the aesthetics.

The backlight unit 200 is positioned below the display panel 100 and supplies light to the display panel 100.

The backlight unit 200 includes a direct light type in which a light source is disposed on the entire lower surface of the display panel 100 to direct the light emitted from the light source directly to the display panel 100, An edge type in which a light source is disposed at one side and a light emitted from the light source is transmitted to the display panel 100 through a light guide plate. In the present invention, either a direct type or an edge type can be applied. That is, although the edge type backlight unit 200 is shown in the drawing, it is not limited thereto.

The backlight unit 200 includes a light source (not shown), a light guide plate 210, an optical sheet 220, and a reflection plate 230.

The light guide plate 210 has a function of changing the path of the light emitted from the light source toward the display panel 100. In order to change the light path, A pattern or a protruding pattern is formed. The optical sheet 220 is formed on the light guide plate 210 and supplies light uniformly to the display panel 100. The optical sheet 220 may be a combination of a diffusion sheet and a prism sheet. The reflection plate 230 is formed below the light guide plate 210 and reflects light leaking below the light guide plate 210 toward the upper side to improve light efficiency.

The support structure 300 supports the display panel 100 and the backlight unit 200 and includes a guide frame 310, a lower case 320, a set cover 330, and a coupling member 340 .

The guide frame 310 guides the position of the backlight unit 200 while supporting the lower surface of the display panel 100.

The lower case 320 is positioned inside the guide frame 310 to receive the backlight unit 200. The lower case 320 may uniformly transmit and discharge heat generated from the backlight unit 200. That is, since heat is generated in the backlight unit 200, a ventilation hole may be required to discharge heat generated in the backlight unit 200. Therefore, when the lower case 320 is formed of a material such as a metal capable of conducting heat, the heat generated from the backlight unit 200 may be transmitted through the lower case 320 and may be discharged to the outside. However, the lower case 320 may be omitted in some cases. In this case, the backlight unit 200 may be supported by the set cover 330. Although not shown in detail, the lower case 320 may be coupled to the guide frame 310 through various coupling structures known in the art such as a bolt / nut or a hook structure.

The set cover 330 serves as a bottom surface and a side cover of the display device, and accommodates the display panel 100 and the backlight unit 200. The set cover 330 is not formed on the upper surface of the display panel 100. The set cover 330 includes a lower surface serving as a bottom cover of the display device and a side surface serving as a side cover of the display device. The side surface of the set cover 300 is in contact with the light shielding member 150 do.

The bezel of the display device can be minimized by reducing the thickness of the side surface of the set cover 330. [ Although not specifically shown, the set cover 330 may be coupled to the guide frame 310 through various coupling structures known in the art such as bolts / nuts or hook structures.

The coupling member 340 serves to prevent the display panel 100 from coming off. As described above, according to the embodiment of the present invention, since the set cover 300 is not formed on the upper surface of the display panel 100, it is possible to prevent the display panel 100 from deviating upward . Therefore, by coupling the display panel 100 to the guide frame 310, the coupling member 340 can prevent the display panel 100 from deviating upward. Such an engaging member 340 may use an adhesive such as a double-sided tape, but is not limited thereto.

FIG. 4 is a schematic cross-sectional view of a display device according to another embodiment of the present invention, which corresponds to a cross section of the line I-I in FIG. That is, FIG. 4 corresponds to a cross section from one side to the other side of the display device in which the panel driver 400 is not formed.

The display device according to FIG. 4 is the same as the above-described display device according to FIG. 3 except that the shielding resin 160 is added and the guide frame 310 and the coupling member 340 are omitted. Therefore, the same reference numerals are assigned to the same components, and only the different components will be described below.

As shown in FIG. 4, the light shielding resin 160 is formed on the side surface of the light shielding member 150. More specifically, the light shielding resin 160 is formed between the light shielding member 150 and the set cover 330. The light shielding resin 160 may prevent light from leaking from the side surface of the display panel 100 together with the light shielding member 150.

The shielding resin 160 may also prevent the display panel 100 from being detached by fixing the display panel 100 to the support structure 300. More specifically, the light shielding resin 160 couples the light shielding member 150 and the set cover 330 so that the display panel 100 can be fixed to the set cover 330. The shielding resin 160 may extend in a region between the lower case 320 and the set cover 330 to join the lower case 320 and the set cover 330. Since the display panel 100, the set cover 330 and the lower case 320 can be coupled by the shielding resin 160 as described above, The coupling member 310 and the coupling member 340 may be omitted. However, the present invention is not limited thereto, and the light shielding resin 160 may not extend to a region between the lower case 320 and the set cover 330. In this case, The member 340 is not omitted.

The light shielding resin 160 may include a base resin, a light shielding material, and a UV curing promoting material.

The base resin may be formed of an acrylate-based polymer as a base material of the light-shielding resin 160 while bonding the light-shielding material and the UV curing accelerator, but is not limited thereto. Optionally, the base resin may be made of a thermally fusible material, in which case the UV cure promoting material may be omitted.

The light blocking material comprises colored particles. As the colored particles, black particles such as carbon black can be used, but the present invention is not limited thereto, and various colored particles capable of realizing a light blocking effect can be used. As an example, titanium oxide particles can be used as the colored particles. When the carbon black is used as a light shielding material, UV curing of the base resin may be difficult. However, when the UV curing accelerator is added to the carbon black, Although the carbon black that absorbs light in the UV region is used as a light shielding material, UV curing of the base resin can be facilitated. The light shielding material may further include plate-shaped particles. When the light blocking material includes the plate-like particles, the light transmission is blocked by the plate-shaped particles, so that the light leakage can be prevented more efficiently. Particularly, the platelet-like particles can be arranged while maintaining their directionality by shrinkage during the UV curing process, and thus can perform an effective light shielding function. In addition, a side effect that the arrangement of the colored particles is uniformly aligned by the plate-like particles can be obtained. The platelet-like particles may be made of a metal oxide such as Al ₂ O ₃ , but are not limited thereto.

The UV curing accelerator is a material for facilitating UV curing of the base resin. Since the light shielding resin 160 includes the UV curing promoting material, the curing process of the base resin can be facilitated even if the blackness of the light blocking material is increased. The UV curing accelerator may comprise light diffusing particles, wherein the UV cured upon UV curing may diffuse into the light diffusing particle at various angles, such that a greater amount of UV So that the curing of the base resin can be facilitated. The light-diffusing particles may be made of polystyrene (PS), polycarbonate (PC), or polyethylene terephthalate (PET), but are not limited thereto. The UV curing accelerator may include a blue pigment. When a blue pigment is included, the transmittance of the irradiated UV for UV curing is increased, and the curing of the base resin can be promoted. The UV curing accelerator may include both light diffusing particles and blue pigment, but may be composed of only light diffusing particles or only blue pigment.

The light shielding resin 160 is not limited to the combination of the base resin, the light shielding material, and the UV curing accelerating material described above, but may be made of various materials known in the art.

The light shielding resin 160 may be additionally formed between the light shielding member 150 and the set cover 330 and the light shielding resin 160 may be provided between the lower case 320 and the set cover 330. [ The guide frame 310 and the engaging member 340 can be omitted by extending to the area between the covers 330. [

5 is a schematic cross-sectional view of a display device according to another embodiment of the present invention, which corresponds to a cross section of the line I-I in FIG. That is, FIG. 5 corresponds to a cross section from one side to the other side of the display device in which the panel driver 400 is not formed.

The display device according to another embodiment of the present invention shown in FIG. 5 is the same as the embodiment shown in FIG. 3 except that the configuration of the light shielding member 150 formed on the side surface of the display panel 100 is changed . Therefore, the same reference numerals are assigned to the same components, and repetitive description of the same components will be omitted.

5, the light blocking member 150 is formed as one body with the first polarizer 130 and the second polarizer 140. As shown in FIG.

The first polarizing plate 130 formed on the upper surface of the first substrate 110 extends to the side surfaces of the first substrate 110 and the second substrate 120 to form the second light blocking member 152 Respectively. Accordingly, the second light blocking member 152 is integrally connected to the first polarizing plate 130 and has the same polarization characteristics as the first polarizing plate 130.

The second polarizing plate 140 formed on the lower surface of the second substrate 120 extends to the side surfaces of the first substrate 110 and the second substrate 120 to form the first light blocking member 151. Accordingly, the first light blocking member 151 is integrally connected to the second polarizing plate 140 and has the same polarizing characteristic as the second polarizing plate 140. [

However, the present invention is not limited thereto, and the second light blocking member 152, which is relatively inwardly formed, may include the first light blocking member 151 extending from the first polarizing plate 130, Or may extend from the second polarizer plate 140.

At this time, the first light blocking member 151 and the second light blocking member 152 may each be curved. Specifically, the first light blocking member 151 extending from the second polarizing plate 140 may be folded at a predetermined radius of curvature toward the first polarizing plate 130 located on the opposite side, and the first polarizing plate 130 The second light blocking member 152 may be folded at a predetermined radius of curvature in the direction of the second polarizing plate 140 located on the opposite side. The radius of curvature of each of the first light blocking member 151 and the second light blocking member 152 may be smaller than the thickness of the display panel 100.

In one embodiment, the first light shielding member 151 and the second light shielding member 152, which are bent and extended in opposite directions to each other, are formed so that at least a portion of each of the light shielding members 151 and 152 is located on the side of the display panel 100 They may overlap each other. To this end, the lengths of the first light blocking member 151 and the second light blocking member 152 may be long enough to bend and overlap each other.

5, the first polarizer 130 may be formed to be long, and then bent along the side surface of the first substrate 110 and the side surface of the second substrate 120. In this case, The second polarizing plate 140 is formed to be long and then bent along the side surface of the first substrate 110 and the side surface of the second substrate 120 to form the second light blocking member 152, The first light shielding member 151 can be formed, and the light shielding member 150 can be formed by a simple process.

5, a light shielding resin 160 may be additionally formed between the light shielding member 150 and the set cover 330, as in the embodiment shown in FIG. In this case, the light shielding resin 160 can fix the light shielding members 150 and 151 and add a light shielding effect.
