In addition, although not shown, a liquid crystal layer may be disposed between the first substrate 100 and the second substrate 110.

An electrode line (EL line) may be disposed on the first substrate 100. Here, the electrode line EL may include a gate line GL and a data line DL intersecting with each other.

Although not shown, a black matrix layer may be formed on the second substrate 110 to define a pixel region.

In addition, although not shown, another electrode, for example, a common electrode may be disposed on the second substrate 110.

Such a second substrate 110 can be referred to as a color filter substrate.

2 to 32 are views for explaining a manufacturing method and a structure of a display panel. In the following description of the parts described in detail above may be omitted.

2 (A), the first substrate 100 and the second substrate 110 on which the electrode line EL and the switching element T are formed can be bonded together using a sealing part 120 .

The seal 120 may be formed on the edge of at least one of the first substrate 100 and the second substrate 110.

2B, the liquid crystal layer 130 may be injected into a region between the first substrate 100 and the second substrate 110 which are adhered together by the seal 120. In this case, as shown in FIG.

Thereafter, as in the case of FIG. 3A, the edge of the display panel can be cut according to a cutting line (CL).

In this cutting process, the first substrate 100, the second substrate 110, and a part of the seal 120 can be cut.

Accordingly, after the cutting process, the ends of the first substrate 100, the second substrate 110, and the seal 120 may be placed on a straight line, as in the case of FIG. 3B.

In this way, by cutting off the edges of the display panel, the size of the bezel area can be reduced.

It is possible to change the cut portion according to the structure of the electrode line EL disposed on the first substrate 100 in the display panel.

For example, as in the case of FIG. 4A, the first substrate 100 and the second substrate 110 are bonded together in a state where the first substrate 100 and the second substrate 110 are bonded together, Cutting the first short side LS1 region of the first substrate 100 and the second short side SS2 of the second substrate 110 along the second cutting line CL2, It is possible to cut along the line CL1.

In this case, although not shown, a pad electrode may be disposed on the first long side LS1 and the second short side SS2 of the first substrate 100 and the second substrate 110, respectively.

4B, the first and second substrates 100 and 110 may be bonded to each other at a first long side LS1 of the first substrate 100 and a second substrate 110 in a state where the first substrate 100 and the second substrate 110 are bonded together, And cutting the second long side (LS2) region of the first substrate 100 and the second substrate 110 along the fourth cutting line CL4 by cutting the second cutting line CL2 along the second cutting line CL2, Cutting the first short side SS1 of the first substrate 100 and the second substrate 110 along the third cutting line CL3 and cutting the first short side SS1 of the first substrate 100 and the second substrate 110, It is possible to cut the second short side SS2 region of the substrate 110 along the first cutting line CL1.

In this case, although not shown, the first long side LS1, the second long side LS2, the first short side SS1, and the second short side SS2 of the first substrate 100 and the second substrate 110, A pad electrode may be disposed on each pad electrode.

After the edge of the display panel is cut, the side of the cut display panel can be grinded using a grinder 200 as in the case of FIG. 5 (A).

Then, as in the case of Fig. 5B, the side surface of the display panel can be smoothly processed. Accordingly, the structural stability of at least one of the first substrate 100 and the second substrate 110 can be improved.

Referring to FIG. 6, a pad electrode ELP may be disposed at an edge of the first substrate 100. In addition, the pad electrode ELP may be electrically connected to the electrode line EL.

A data pad electrode DLP electrically connected to the data line DL is disposed in a second long side LS2 region of the first substrate 100 and a second short side And a gate pad electrode GLP electrically connected to the gate line GL may be disposed in the gate line SS2.

The pad electrode ELP can be located at least at one end of the electrode line EL.

The pad electrode ELP may be integrated with the electrode line EL. Alternatively, after the pad electrode ELP is formed separately from the electrode line EL, it may be possible to electrically connect the pad electrode ELP and the electrode line EL.

The seal 120 may be formed at a position overlapping the pad electrode ELP, that is, the gate pad electrode GLP and the data pad electrode DLP. In other words, the gate pad electrode GLP and the data pad electrode DLP are overlapped with the seal 120 in a vertical direction crossing the second direction DR2 and the third direction DR3 .

Hereinafter, the vertical direction can be referred to as a first direction (First Direction, DR1). In addition, the second direction DR2 and the third direction DR3 can be collectively referred to as a horizontal direction.

In addition, the region where the seal 120 is formed can be referred to as a dummy area (DA). The area surrounded by the dummy area DA can be referred to as an effective area (AA). The effective area AA can be regarded as a region in which an image is displayed.

The width of the pad electrode ELP can be larger than the width of the electrode line EL.

7A and 7B, the width W1 of the gate pad electrode GLP is larger than the width W2 of the gate line GL and the width W1 of the data pad electrode DLP is larger than the width W2 of the gate line GL, The width W3 of the data line DL can be larger than the width W4 of the data line DL.

In this case, it is possible to easily electrically connect the gate pad electrode GLP and the data pad electrode DLP to a flexible substrate (not shown).

Hereinafter, it is assumed that the width of the pad electrode ELP is larger than the width of the electrode line EL, but it is also possible that the width of the pad electrode ELP and the width of the electrode line EL are substantially equal to each other .

The first substrate 100 may further include an insulating layer for insulating the electrode lines EL.

For example, as in the case of FIG. 8A, the data line DL and the data pad electrode DLP are formed on the first substrate 100, and then, as in the case of FIG. 8B, A first insulating layer 140A covering the data line DL and the data pad electrode DLP may be formed on one substrate 100. [

9A, the gate line GL and the gate pad electrode GLP may be formed on the first substrate 100 on which the first insulating layer 140A is formed. For example, the gate line GL may be formed on the first insulating layer 140A, and the gate pad electrode GLP may be formed on the first substrate 100. Referring to FIG.

9B, a second insulating layer 140B is formed on the first substrate 100 so as to cover the first insulating layer 140A, the gate line GL, and the gate pad electrode GLP, Can be formed.

In this case, an insulating layer, that is, a second insulating layer 140B, may be positioned between the gate line GL and the data line DL. Thus, the gate line GL and the data line DL can be electrically insulated.

9, when the gate line GL and the gate pad electrode GLP are formed, at least a part of the gate line GL is located in a layer different from the gate pad electrode GLP or the gate pad electrode GLP May be located on a different layer from the gate line GL.

Although not shown, a step of forming the switching element T is formed between the step of forming the data line DL (FIG. 8A) and the step of forming the gate line GL (FIG. 9A) Can be added.

Hereinafter, the first insulating layer 140A and the second insulating layer 140B will be collectively referred to as an insulating layer 140. [ The structure of the insulating layer 140 in the present invention is not limited thereto. For example, the insulating layer 140 may be formed in a three-layer structure or a four-layer structure.

A part of the gate pad electrode GLP and the data pad electrode DLP are exposed to the side surfaces of the gate pad electrode GLP and the data pad electrode DLP in the cutting process to the first substrate 100 and the second substrate 110, And the seal 120 together.

6, the data pad electrode DLP is disposed on the second long side LS2 of the first substrate 100 and the gate pad electrode DL2 is formed on the second short side SS2 of the first substrate 100. As described above, (GLP) is disposed.

10 (A), if the second long side LS2 of the display panel 10 is cut, as shown in FIG. 10 (B), the side surface of the data pad electrode DLP May be exposed between the first substrate 100 and the insulating layer 140. In other words, one end surface of the data pad electrode DLP may be exposed between the first substrate 100 and the insulating layer 140.

11A, the second short side SS2 of the display panel 10 is cut so that the side surface of the gate pad electrode GLP is covered with the second short side SS2, as in the case of FIG. 11B. 1 substrate 100 and the insulating layer 140. In this case, In other words, one end surface of the gate pad electrode GLP may be exposed between the first substrate 100 and the insulating layer 140.

9 to 10, one end of the pad electrode ELP may be positioned on a straight line with the end of the seal 120. In other words, one end of the pad electrode ELP can coincide with the end of the seal 120.

12, a side electrode 150 may be formed on a side surface of the cut display panel 10. In the following drawings, it is assumed that the electrode line EL and the pad electrode ELP are formed on the same layer for convenience of explanation. However, the electrode line EL and the pad electrode ELP are formed in different layers It is also possible. This has been described above with reference to FIG.

The side electrode 150 may be connected to the exposed side (end surface) of the pad electrode ELP in the cutting process.

The side electrode 150 may include a portion connected to the pad electrode ELP as well as a side portion of the seal 120. In this case, the area of the side electrode 150 can be increased to facilitate the electrical connection between the flexible substrate and the side electrode 150, which is not shown.

In addition, the side electrode 150 may include a portion located on the side surface of the first substrate 100.

The side electrodes 150 are spaced apart from the first substrate 100, the second substrate 110 and the seal 120 by a predetermined length D1 in the horizontal direction (the second direction DR2 or the third direction DR3) And may include extended portions. In other words, the side electrodes 150 may be arranged in a more direction than the first substrate 100, the second substrate 110, and the body 120 in the horizontal direction (the second direction DR2 and / or the third direction DR3) Can be extended.

The side electrode 150 may preferably have a sufficiently high electric conductivity so as to more efficiently supply a driving signal supplied through a flexible substrate not shown to the pad electrode ELP and the electrode line EL.

Since the side electrode 150 is connected to at least one end surface of the pad electrode ELP after the electrode line EL and the pad electrode ELP are formed, the side surface electrode 150 and the pad electrode ELP ) May increase the electrical resistance.

The electric conductivity of the side electrode 150 is more than the electric conductivity of the pad electrode ELP and the electrode line EL in order to compensate for the loss due to the electric resistance at the interface between the side electrode 150 and the pad electrode ELP. Higher may be desirable.

In other words, the side electrode 150 may include a material having electrical conductivity higher than that of the electrode line EL and the pad electrode ELP.

For example, assuming that the electrode line EL and the pad electrode ELP are formed of copper (Cu), the side electrode 150 may be formed of aluminum (Al), silver (Ag), gold As shown in FIG.

As such, the material of the electrode line EL and the pad electrode ELP may be different from the material of the side electrode 150.

When the electrical resistance at the interface between the side electrode 150 and the pad electrode ELP is negligibly low, the electrical conductivity of the side electrode 150 may be approximately equal to the electrical conductivity of the pad electrode ELP. In this case, the material of the electrode line EL and the pad electrode ELP may be the same as the material of the side electrode 150.

The side electrode 150 may be manufactured by various methods. A method of manufacturing the side electrode 150 will be described in detail below.

The electrode material layer 300 can be formed on the side surface of the display panel 10 as shown in FIG. Such an electrode material layer 300 may include a photosensitive material.

14A, a photo mask 310 having a predetermined pattern formed thereon is disposed on the electrode material layer 300, and light such as ultraviolet light is irradiated to the photo mask 310 The electrode material layer 300 can be irradiated through the formed pattern.

Then, a part of the electrode material layer 300 exposed to light by the photosensitive material can be cured.

Thereafter, when a process such as etching or sandblasting is performed, the hardened portion remains in the electrode material layer 300, and the portion that is not hardened is removed, whereby, as in the case of FIG. 14 (B) A side electrode 150 may be formed on a side surface of the display panel 10.

The process described above can be considered as an example of the photo process. The side electrode 150 manufactured through the photolithography process can have a shape as shown in FIG.

It is also possible to manufacture the side electrode 150 by using an offset method different from the photo process. The following is a look at this. The offset method is an example of a direct patterning printing method.

Referring to FIG. 16A, an electrode material 410 in a paste state or a slurry state can be applied to the surface of a mold 400.

Thereafter, as shown in FIG. 16B, the blanket 420 can be moved from the surface of the mold 400 to which the electrode material 410 is applied. Then, the electrode material 410 may be deposited on the surface of the blanket 420.

The blanket 420 may preferably be in the form of a roller to allow the electrode material 410 to be more effectively imbedded. Thus, when the blanket 420 is in the form of a roller, the blanket 420 may be rotated on the surface of the mold 400 so that the electrode material 410 may be embedded.

16 (C), the electrode material 410 deposited on the surface of the blanket 420 while moving the blanket 420 with the electrode material 410 on the side of the cut display panel 10, To be printed on the side surface of the display panel 10.

Thereafter, the side electrode 150 may be formed on the side surface of the display panel 10 by performing the firing or drying process.

An example of the side electrode 150 manufactured in this manner is shown in Fig.

It is also possible to manufacture the side surface electrode 150 using a photolithography process, an offset process, and another plating process. The plating method may include an electrolytic plating method and an electroless plating method. A method of forming the side electrode 150 by electrolytic plating in the plating method will be described below.

The display panel 10 with the edge cut to expose the pad electrode ELP may be deepened into the electrolytic solution 510, as in the case of FIG. 18A. In addition, the metal electrode 520 can be deeply doped into the electrolytic solution 510.

In this state, if a predetermined voltage is applied to the electrode line EL or the pad electrode ELP and the metal electrode 520, the metal contained in the electrolytic solution 510, as in the case of FIG. 18B, The component 530 is deposited on the exposed side of the pad electrode ELP, so that the side electrode 150 can be formed.

For example, when a positive voltage is applied to the metal electrode 520 and a negative voltage is applied to the pad electrode ELP or the electrode line EL, And may collect on the side surface of the electrode ELP and precipitate.

An example of the side electrode 150 formed by this method is shown in Figs. 19A and 19B.

Here, the metal component 530 may include a material having high electrical conductivity, such as silver (Ag). In this case, the side electrode 150 may also be formed of a silver (Ag) material.

In addition, the size of the metal component 530 for effective precipitation can be approximately a few nanometers. In addition, the electrolytic solution 510 can be an aqueous solution of Ag-Aceate. In addition, the concentration of the electrolytic solution 510 can be about 0.1 wt% or more.

Alternatively, it may be possible to hold the electrolytic solution 510 in a predetermined vessel 500 and apply a voltage to the vessel 500. In this case, it is possible not to use the metal electrode 520.

A method of forming the side electrode 150 by the electroless plating method in the plating method will be described below.

20 (A), the display panel 10 having the edges cut to expose the pad electrode ELP can be deeply dipped in the H2SO4 aqueous solution. Thus, the oxide film formed on the exposed surface of the pad electrode ELP can be removed.

If the pad electrode ELP is made of a material which is not easily oxidized, the step of FIG. 20 (A) may be omitted.

In the case where the pad electrode ELP is made of a material such as copper having a relatively high possibility of being oxidized, the copper material is oxidized on the exposed side of the pad electrode ELP to form a copper oxide film Is likely to be relatively high. Therefore, it may be preferable to perform the step of removing the oxide film on the exposed side of the pad electrode ELP, as shown in Fig. 20 (A).

Thereafter, as in the case of FIG. 20 (B), the pad electrode ELP is deposited in the aqueous solution of palladium (Pd) for forming a seed in a state where the oxide film is removed from the side surface of the pad electrode ELP, can do.

In this case, the palladium (Pd) material contained in the palladium (Pd) aqueous solution adheres to the side surface of the pad electrode ELP to form the seed 540 as shown in FIG. 20C. In this case, the seed 540 may be made of palladium (Pd) material.

Here, only the case where the seed 540 is formed using palladium (Pd) is described, but it is also possible to form the seed 540 using another metallic material.

21A, the side surface of the pad electrode ELP may be deeply doped into the electrolytic solution 550 with the seed 540 formed on the side surface of the pad electrode ELP. Here, the electrolytic solution 550 may include a metal material for forming the side electrode 150. For example, the electrolytic solution 550 can be an aqueous solution of Ag-Aceate.

Deeping the side surface of the pad electrode ELP in the electrolytic solution 550 in the state where the seed 540 is formed on the side surface of the pad electrode ELP as described above allows the metal material contained in the electrolytic solution 550 to be adhered to the seed 540 And the side electrode 150 as shown in FIG. 21 (B) by being gathered on the side surface of the pad electrode ELP.

Here, the seed 540 may improve the electrode growth rate and reduce the time required for the manufacturing process of the side electrode 150. [

Referring to FIG. 21B, a seed 540 may be positioned between the side surface of the pad electrode ELP and the side electrode 150.

For example, it is possible that the seed 540 is made of palladium (Pd), the side electrode 150 is made of silver (Ag), and the pad electrode ELP is made of copper . In this case, a seed 540 including a material different from the material of the side electrode 150 and / or the pad electrode ELP may be formed between the side electrode 150 and the pad electrode ELP.

The structure and shape of the side electrode 150 formed in accordance with this method may be similar to those of FIGS. 19A and 19B.

Referring to FIG. 22, a protective electrode (protection electrode) 150C may be formed on the surface of the pad electrode ELP. In detail, the side electrode 150 may include a base electrode 150B and a protective electrode 150C coated on the surface of the base electrode 150B.

Here, the base electrode 150B may be located at one end of the pad electrode ELP. That is, the base electrode 150B may be connected to one end surface of the pad electrode ELP.

The thickness D3 of the protective electrode 150C may be smaller than the thickness D2 of the base electrode 150B in the horizontal direction (the second direction DR2 or the third direction DR3).

The protective electrode 150C may include a material which is relatively inferior in oxidation compared to the material of the pad electrode ELP and / or the base electrode 150B. That is, the protective electrode 150C can prevent the base electrode 150B from being oxidized. For example, the protective electrode 150C may be made of nickel (Ni) or gold (Au).

This protective electrode 150C can also be formed by a plating method.

For example, after the base electrode 150B is formed on the side surface of the pad electrode ELP by the same method as shown in FIGS. 20 to 21, a protective electrode 150C is formed on the surface of the base electrode 150B, It can be formed by the same method as that shown in FIG.

In this case, another seed 560 may be formed between the base electrode 150B and the protective electrode 150C, as in the case of FIG. The material of another seed 560 in which the base electrode 150B and the protective electrode 150C are formed is the same as the material of the seed 540 formed between the pad electrode ELP and the base electrode 150B It is possible.

On the other hand, in order to electrically connect the flexible substrate (not shown) and the side electrode 150 effectively, it may be desirable to sufficiently increase the area of the side electrode 150.

24, the side electrode 150 may include a portion located on a side surface of the first substrate 100 and a portion located on a side surface of the second substrate 110. In addition,

In this case, the width D4 in the vertical direction (the first direction DR1) of the side electrode 150 is set to be larger than the width D4 in the horizontal direction (the second direction DR2 or the third direction DR3) of the pad electrode ELP May be larger than the width (D10) Alternatively, the width D4 in the vertical direction (first direction DR1) of the side electrode 150 is greater than the width D4 of the side electrode 150 in the horizontal direction (second direction DR2 or third direction DR3) May be greater than the width D5.

In addition, the width D4 in the vertical direction (the first direction DR1) of the side electrode 150 may be larger than the interval D6 between the adjacent side electrodes 150. [

The gap D8 between the side electrode 150 and the first substrate 100 in the vertical direction DR1 may be smaller than the gap D6 between the adjacent side electrodes 150. [ Alternatively, the distance D7 between the side electrodes 150 and the end of the second substrate 110 in the vertical direction DR1 may be smaller than the spacing D6 between the adjacent side electrodes 150.

When the pad electrode ELP is formed on the first substrate 100, the gap D8 between the side electrode 150 and the end of the first substrate 100 in the vertical direction DR1 is substantially equal to the distance D2 in the vertical direction DR1. May be smaller than a distance (D7) between the electrode (150) and the end of the second substrate (110).

On the other hand, in order to sufficiently reduce the electric resistance in the boundary region between the pad electrode ELP and the side electrode 150, it may be preferable to sufficiently increase the area of the cross section of the pad electrode ELP. 25, the width D10 of the pad electrode ELP in the horizontal direction (the second direction DR2 or the third direction DR3) is equal to the width D10 of the gap between the adjacent pad electrodes ELP D11).

Here, the electrodes 620, 640, 650 may include a portion connected to the side electrode 150, that is, a connection electrode 620. The base layer 610 and the cover layer 660 may each include a flexible Resin material so that the flexible substrate 600 can be bent.

Here, the case where the electrodes 620, 640 and 650 are single-layered in the flexible substrate 600 is described as an example, but the present invention is not limited thereto. For example, in the flexible substrate 600 according to the present invention, the electrodes 620, 640 and 650 may have a plurality of layers.

At least one of the base layer 610 and the cover layer 660 of the flexible substrate 600 may include a black material. In this case, the flexible substrate 600 may appear black.

Alternatively, it is also possible to form an organic metal layer 701 by laminating a sheet of an organic material including a metal material on the side of the display panel 10.

Thereafter, the flexible substrate 600 may be disposed on the organic metal layer 701, and pressure may be applied to the flexible substrate 600 at a predetermined temperature.

Here, if the ambient temperature rises above the critical temperature, the chemical bond between the metal material and carbon is broken in the organometallic compound forming the organic metal layer 701, and the metal material is electrically connected to the connection between the side electrode 150 and the flexible substrate 600 So that the metal layer 700 can be formed between the electrodes 620.

That is, the organic layer 703 may include an acrylic material and / or an epoxy material. Since the organic layer 703 has adhesiveness, the flexible substrate 600 can be firmly attached to the side surface of the display panel 10. The organic layer 703 may include a portion of the metal material 702 included in the organic metal layer 701 that is not included in the metal layer 700.

It is possible to change the traveling direction of at least one data line DL included in the data line group DLG in the dummy area DA to connect the data line group DLG to the flexible substrate 600. [ For example, it is possible to change the traveling direction of the data line DL so that the interval between the adjacent data lines DL in the first data line group DLG1 becomes small.
