BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display panel and a method for manufacturing the same, and more particularly, to a liquid crystal display panel and a method for manufacturing the same, which improve image quality by preventing gravity failure.

In general, a liquid crystal display device is a display device that displays a desired image by separately supplying data signals according to image information to pixels arranged in a matrix form, and adjusting light transmittance of the pixels.

To this end, the liquid crystal display includes a liquid crystal display panel in which pixels are arranged in a matrix and a driving unit for driving the pixels.

The liquid crystal display panel is bonded to an array substrate on which a thin film transistor array is formed and a color filter substrate on which a color filter is formed to maintain a uniform cell gap, and the array substrate and the color filter substrate. The liquid crystal layer is formed in the cell gap therebetween.

In this case, an alignment layer is formed on the surface of the array substrate and the color filter substrate facing each other, and rubbing is performed to arrange the liquid crystals of the liquid crystal layer in a predetermined direction.

In addition, the array substrate and the color filter substrate are bonded by a seal line formed along the outer edge of the pixel portion, and the outer surface of the bonded array substrate and the color filter substrate is provided with a polarizing plate and a phase difference plate. By selectively configuring the elements, the liquid crystal display panel having high luminance and contrast characteristics is formed by changing the traveling state of the light or changing the refractive index.

Hereinafter, the liquid crystal display panel configured as described above will be described in detail with reference to the accompanying drawings.

1 is a plan view schematically illustrating a structure of a general liquid crystal display panel.

As shown in the drawing, the liquid crystal display panel includes a pixel portion 35 in which pixels are arranged in a matrix form to display an image, and a gate pad portion 31 connected to gate lines 16 of the pixel portion 35. ) And a data pad part 32 connected to the data lines 17.

In this case, the gate pad part 31 and the data pad part 32 are formed in an edge region of the array substrate 10 which does not overlap the color filter substrate 5, and the gate pad part 31 is a gate driver (not shown). The scan signal supplied from the C) to the gate lines 16 of the pixel unit 35, and the data pad unit 32 supplies the image information supplied from the data driver (not shown) to the data of the pixel unit 35. To the lines 17.

In addition, data lines 17 to which image information is applied and gate lines 16 to which a scan signal is applied are arranged on the array substrate 10 so that the data lines 17 and the gate line 16 are intersected with each other. Thin film transistors (not shown) and pixel electrodes (not shown) are respectively provided in regions partitioned by the plurality of pixels.

Although not shown in the drawing, the color filter substrate 5 may be a common electrode that is a color electrode partitioned for each pixel by a black matrix and a counter electrode of the pixel electrode formed on the array substrate 10. An electrode is provided.

The color filter substrate 10 and the array substrate 5 configured as described above are maintained by a spacer (not shown), and a predetermined cell gap is maintained and bonded by the seal pattern 50 formed along the outer portion of the pixel portion 35. .

In this case, a method of forming the spacers is a method of randomly scattering by using a ball spacer such as glass beads or plastic beads, but in recent years, as the liquid crystal display panel is gradually enlarged, the ball spacers are aggregated. As a result, it is difficult to maintain precise cell gaps and poor image quality occurs.

Therefore, in the case of a large liquid crystal display panel, column spacers (or patterned spacers) formed by directly patterning the array substrate 5 or the color filter substrate 10 without using ball spacers are used.

At this time, the thickness of the liquid crystal layer, that is, the cell gap between the array substrate 5 and the color filter substrate 10 becomes one of the most important items in the design of the liquid crystal display panel. That is, when the thickness of the cell gap is changed according to the position of the panel, a serious problem occurs that the screen display characteristics are deteriorated due to a change in color or luminance.

In particular, when a liquid crystal display panel is commercialized as a notebook or a general liquid crystal display monitor and a television, most of the liquid crystal display panels are vertically leaked. In addition, after the liquid crystal display panel is assembled into a module for this purpose, it is often vertically erected during the test process.

As described above, the vertically oriented liquid crystal display panel is affected by high temperature and gravity, causing a gravity failure phenomenon in which the liquid crystal material is concentrated downward. As a result, an unbalanced cell gap occurs between the upper and lower portions of the liquid crystal display panel.

Such a problem becomes a bigger problem in the current trend of larger panels, because the larger the panel, the larger the amount of liquid crystal introduced as the substrate is enlarged, and thus the more poor the gravity occurs.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a liquid crystal display panel and a method of manufacturing the same to solve the problem of gravity failure by forming a patterned spacer using a SAM process.

Other features and objects of the present invention will be described in detail in the configuration and claims of the invention below.

In order to achieve the above object, the liquid crystal display panel of the present invention comprises a color filter substrate consisting of a color filter and a black matrix; An array substrate in which a plurality of gate lines and data lines cross each other to define a plurality of pixels; A gold pattern formed on at least one of the color filter substrate and the array substrate; And a column spacer pattern formed on the gold pattern to maintain a constant cell gap between the array substrate and the color filter substrate.

In addition, the manufacturing method of the liquid crystal display panel of the present invention comprises the steps of forming a color filter and a black matrix on the color filter substrate; Forming a thin film transistor on the array substrate; Forming a gold pattern on at least one of the color filter substrate and the array substrate; Forming a column spacer pattern on the gold pattern by applying an organic material including sulfur atoms to the substrate on which the gold pattern is formed; And bonding the color filter substrate and the array substrate.

Hereinafter, exemplary embodiments of a liquid crystal display panel and a method of manufacturing the same will be described in detail with reference to the accompanying drawings.

2 is a plan view schematically illustrating a part of an array substrate according to a first exemplary embodiment of the present invention.

At this time, although N gate lines and M data lines cross MxN pixels on the actual array substrate, only the (m, n) -th pixel is shown in the figure for simplicity.

As shown in the figure, the array substrate of the (m, n) -th pixel 110 includes an n-th gate line 116n to which a scan signal is applied from an external driving circuit (not shown), and m to which an image signal is applied. A first data line 117m, a thin film transistor that is a switching element formed at an intersection of the gate line 116n and the data line 117m, and a pixel electrode 118 connected to the thin film transistor.

The thin film transistor includes a gate electrode 121 connected to the gate line 116n, a source electrode 122 connected to the data line 117m, and a drain electrode 123 connected to the pixel electrode 118. In addition, the thin film transistor may include a first insulating film (not shown) for insulating the gate electrode 121 and the source / drain electrodes 122 and 123 and the source electrode by a gate voltage supplied to the gate electrode 121. And a semiconductor layer (not shown) forming a conductive channel between the 122 and the drain electrode 123. In this case, a second insulating film (not shown) having a contact hole 140 is formed on the drain electrode 123, and the drain electrode 123 and the pixel electrode 118 are electrically connected through the contact hole 140. Will be.

A portion of the pixel electrode 118 protrudes toward the n-1 th gate line, that is, the front gate line 116n-1, to form a storage electrode, and the storage electrode is connected to a portion of the front gate line 116n-1. Overlap will form a storage capacitor.

The storage capacitor serves to maintain the pixel voltage charged in the pixel electrode 118 until the next pixel voltage is charged.

The array substrate 110 configured as described above is bonded to the upper color filter substrate (not shown) by the column spacer pattern 130 positioned on the gate lines 116n-1 and 116 and the data lines 117m and 117m + 1. The liquid crystal display panel is constructed.

Although not shown in the drawing, a black matrix, a color filter, and a common electrode are formed on the color filter substrate, and the black matrix is patterned at a boundary area of the pixels to block leakage of light generated from the backlight and to determine adjacent pixels. Prevents color mixing.

In this case, the column spacer pattern 130 is patterned on the color filter substrate, and is formed in the black matrix region of the color filter substrate, which does not affect the opening ratio.

The column spacer pattern 130 of the present embodiment is formed using SAM technology. For example, ethanol in which SAM molecules are dissolved after a gold (Au) pattern is formed on the color filter substrate or the array substrate 110 is formed. By immersing the color filter substrate or the array substrate in an ethanol container, the SAM layer, that is, the column spacer pattern 130, may be formed on the gold pattern.

In this case, when the gold pattern is patterned and formed in pixel units, the column spacer pattern 130 formed thereon is also formed in the same lattice shape in pixel units as shown in the figure, thereby preventing the lowering of liquid crystals. . The result is a solution to the problem of gravity failure.

The SAM technique used herein is a technique for forming a single layer film by using a combination of gold and sulfur (S) atoms, and using a spacer of an organic material containing sulfur atoms in the same form as the gold pattern where a gold pattern is formed. The spacer pattern may be formed, and if the column spacer pattern having the lattice shape in the pixel unit is formed as in the present exemplary embodiment, the lowering of the liquid crystal may be prevented and thus the gravity deficiency may be solved.

SAM technology is generally used to improve device performance in fabricating organic semiconductor (OSC) applied organic thin film transistors. Through this, many researches for depositing organic semiconductor materials on lower layers having excellent surface properties have been conducted. It is reported that the effect is excellent.

The SAM treatment forms a hydrophobic organic film on the insulating layer to improve the interfacial property between the insulating layer and the semiconductor layer. The organic film has a molecular array of films deposited on the organic film by arranging organic molecules in a predetermined direction. To control or improve the microstructure.

3 illustrates a state in which a SAM layer is formed on a gold or silicon oxide layer (SiO ₂ ). As illustrated in the drawing, the SAM layer 190 includes a head part 170 and a tail part 180. When the head portion 170 is seated on the substrate 110, the tail portion 180 is generated.

FIG. 4 is a cross-sectional view taken along line II-II 'of the liquid crystal display panel of FIG. 2.

As shown in the figure, the liquid crystal display panel is bonded to the array substrate 110 on which the thin film transistor array is formed and the color filter substrate 105 on which the color filter 107 is formed so that a uniform cell gap is maintained. ) And a liquid crystal layer (not shown) are formed in the cell gap between the color filter substrate 105 and the color filter substrate 105.

In this case, the array substrate 110 is a substrate on which the gate electrode 121 and the gate line 116n formed on the substrate 110 made of a transparent insulating material such as glass, and the gate electrode 121 and the gate line 116n are formed. The first insulating film 115A stacked over the entire surface of the substrate 110, the semiconductor layer 124 formed on the first insulating film 115A, and activated when a signal is applied to the gate electrode 121, and the semiconductor layer 124. ) And a second insulating film 115B formed on the source / drain electrodes 122 and 123 formed on the source / drain electrodes 122 and 123 to protect the device, and the drain through the contact hole. The pixel electrode 118 is connected to the electrode 123.

In addition, a black matrix 106, a color filter 107, an overcoat layer (not shown) and a common electrode 108 are formed on the color filter substrate 105, and the black matrix 106 is formed. Patterned in the boundary region of the pixels to block the leakage of light generated from the backlight (not shown), and serves to prevent the mixing of adjacent pixels.

In this case, the color filter 107 is partially overlapped with the black matrix 106 and formed to correspond to the unit pixel, and the sub-color filter of red (R), green (G), and blue (B) colors is formed. The overcoat layer is formed to planarize the upper surfaces of the black matrix 106 and the color filter 107.

A gold pattern 160 and a column spacer pattern 130 are formed on the common electrode 108 in the black matrix 106 to maintain a uniform cell gap between the array substrate 110 and the color filter substrate 105. It will play a role.

As described above, the column spacer pattern 130 may be formed by dipping or spin coating a SAM containing sulfur atoms, ie, an organic material for spacers, on the color filter substrate 105 on which the gold pattern 160 is formed. It is formed by the coating method.

The column spacer pattern 130 may be formed in a region of the black matrix 106 of the upper color filter substrate 105 to prevent a decrease in the aperture ratio. It is possible to prevent and keep the cell gap uniform.

As described above, the case in which the column spacer pattern is formed on the upper color filter substrate is described as an example. However, the present invention is not limited thereto, and a gold pattern is formed on the lower array substrate and the column is formed using SAM technology. It is also possible to form a spacer pattern.

In addition, the column spacer pattern of the present embodiment is formed by patterning to have a lattice shape in one pixel unit, but this is just an example, and the present invention is not limited thereto. It can also be formed.

In addition, by forming the gold pattern on the array substrate or the color filter substrate only in the horizontal direction in the gate line direction other than the lattice shape, the column spacer pattern may be formed in the same horizontal direction as the gold pattern.

The manufacturing method of the liquid crystal display panel according to the present embodiment configured as described above is largely an array process for forming an array substrate, a color filter process for forming a color filter substrate, and a unit liquid crystal display panel by combining the array substrate and the color filter substrate. It is made of a cell process to form a, looking at this in more detail as follows.

First, a thin film transistor which is a switching element which is arranged vertically and horizontally on a transparent insulating substrate such as glass to define a plurality of pixel regions and is connected to the gate line and the data line in each pixel region. To form. In addition, the pixel electrode is connected to the thin film transistor through the array process and drives the liquid crystal layer as a signal is applied through the thin film transistor. In the transverse electric field mode, the pixel electrode and the common electrode forming the horizontal electric field are formed together in the liquid crystal layer through the array process.

In addition, a color matrix is formed on the color filter substrate to distinguish between a color filter composed of red, green, and blue sub-color filters that implement color by a color filter process, and the sub-color filter, and to block light passing through the liquid crystal layer. do. A common electrode facing the pixel electrode of the array substrate is formed on the substrate on which the black matrix and the color filter are formed.

In this case, a gold pattern patterned in a predetermined shape is formed on the common electrode, and a column spacer pattern made of an organic material containing sulfur atoms is formed on the gold pattern by using a SAM technique. It will be described in detail with reference to the drawings.

5A to 5E are cross-sectional views sequentially illustrating a manufacturing process of a color filter substrate including column spacers.

As shown in FIG. 5A, a black matrix 106 is formed to block unnecessary light on a substrate 105 made of a transparent insulating material such as glass.

The black matrix 106 may be an organic film made of a resin material, for example, acrylic, epoxy or polyimide resin including any one of carbon black and black pigment. The colored organic resin of etc. can be applied.

Subsequently, as shown in FIG. 5B, a color filter 107 including red (R), green (G), and blue (B) sub-color filters is formed in the image display region between the black matrices 106. do.

In this case, a method of forming a color filter generally includes a dye method and a pigment method according to the material of the organic filter used in manufacturing the color filter, and there are dyeing methods, electrodeposition methods, and printing methods depending on the manufacturing method. The most common method used in the production of color filters is pigment dispersion.

The said pigment dispersion method is a method of forming a color filter by repeating the process of apply | coating, exposing, and developing the resist which was prepared and photosensitive with the pigment prepared previously.

The color resist used in the pigment dispersion method is composed of photopolymerizable photosensitive compositions such as photopolymerization initiators, monomers, and binders and organic pigments that realize color as main components.

In the photopolymerizable photosensitive composition, a photopolymerization initiator is a general term for three kinds of six-membered cyclic compounds represented by a molecular formula of C ₃ H ₃ N ₃ having high sensitivity and stability of triazine (nitrogen containing three atoms) generating radicals by receiving light. ) -Based compound is used, the monomer is converted into a polymer (polymer) form after the polymerization reaction by the radical is not dissolved in the solvent. The binder serves to maintain the liquid monomer in the form of a film at room temperature to withstand the developer, stabilize the pigment dispersion, and maintain the reliability of heat resistance, light resistance, chemical resistance, etc. of the color filter pattern.

Pigments use organic materials with excellent light resistance and heat resistance. Pigment particles are generally opaque by scattering light, but when the particle size is smaller than the wavelength of light, the pigment transmits light and becomes transparent. Characteristics.

Next, as illustrated in FIG. 5C, an overcoat layer 109 made of a transparent insulating material and a common electrode 108 made of a transparent conductive material are formed on the entire surface of the substrate 105.

In this case, the overcoat layer 109 may be formed of a transparent resin having an insulating property to planarize the substrate 105 on which the color filter 107 is formed and to prevent elution of the pigment ions, and in particular, an acrylic resin or an epoxy resin. Can be formed.

In this embodiment, as the organic film of the resin material is applied to the black matrix 106, the driving failure of the liquid crystal layer due to the step difference is prevented in the region where the black matrix 106 and the color filter 107 overlap. In order to form the overcoat layer 109, the present invention is not limited thereto. When the color filter formed to correspond to the pixels is formed so as not to overlap the black matrix, a separate overcoat layer for surface planarization is not required. .

Next, as shown in FIG. 5D, an Au pattern 160 is formed on the color filter substrate 105 configured as described above, wherein the gold pattern 160 reduces the aperture ratio of the pixel. It is formed in the area of the black matrix 106 to prevent.

At this time, the shape of the color spacer pattern to be formed by using the SAM technology to be described later is determined according to the shape of the gold pattern 160, in the present invention, the gold pattern 160 to solve the problem of gravity and cell gap unevenness It is formed in the form of a lattice in the pixel unit or a straight line in the horizontal direction.

Next, as shown in FIG. 5E, a column spacer pattern 130 is formed on the gold pattern 160 of the color filter substrate 105. As described above, the column spacer pattern 130 is formed on the gold pattern 160 in the black matrix 106 region of the color filter substrate 105 by using an organic material containing sulfur atoms.

The column spacer pattern 130 is mainly formed on the gold pattern 160 using a dipping or spin coating method.

That is, the organic material containing the sulfur atom may be formed by coating the upper portion of the gold pattern 160 by spin coating in the form of a solution or by simply dipping the color filter substrate 105 in a bath containing the organic material in a solution state. Can be formed.

In addition, the column spacer pattern 130 may be formed by printing at a desired position by a printing method.

Meanwhile, in the present exemplary embodiment, the case in which the column spacer pattern 130 is formed on the color filter substrate 105 is described as an example. However, the present invention is not limited thereto, and the column spacer pattern 130 may be formed in an array substrate. In this case, the gold pattern 160 is formed on the array substrate 110, and then the column spacer pattern 130 is formed on the array substrate 110 using SAM technology.

Subsequently, an alignment layer is applied to the array substrate and the color filter substrate, respectively, and then the alignment layer is provided to provide alignment control force or surface fixation force (ie, pretilt angle and alignment direction) to the liquid crystal molecules of the liquid crystal layer formed between the two substrates. Orientation treatment. In this case, a rubbing or photoalignment method may be applied as the alignment treatment method.

Next, the sealant and the silver paste are applied to the outer portion of the color filter substrate and a liquid crystal layer is formed on the array substrate.

Methods of forming the seal pattern include a method of printing with a screen mask and a method of forming a seal pattern having a desired shape by using a movable sealant dispenser.

The method of forming a seal pattern using the screen mask described above is currently the most common method because of the excellent convenience of the process. However, the screen mask method has a disadvantage in that the screen is in contact with the alignment film formed on the substrate, so that the alignment film is poor, and it is difficult to cope with the large area of the substrate. In addition, in order to form a seal pattern using the screen mask method, a sealant is applied to the entire surface of the screen on which the pattern is formed, and the seal is pushed with a rubber squeeze to print the sealant.

In the seal dispenser method, one or two syringe-type dispensers equipped with small circular or rectangular nozzles are moved to print the sealant on the seal area outside the substrate.

Meanwhile, the method of forming the liquid crystal layer is classified into a vacuum injection method and a dropping method, which will be described in detail as follows.

First, in the vacuum injection method, the liquid crystal inlet of the unit liquid crystal display panel separated from the large-area mother substrate is immersed in a container filled with liquid crystal in a chamber in which a constant vacuum is set, and then the degree of vacuum is changed, thereby allowing the inside of the liquid crystal display panel to change. The liquid crystal is injected into the liquid crystal display panel by an external pressure difference. When the liquid crystal is filled inside the liquid crystal display panel, the liquid crystal inlet is sealed to form the liquid crystal layer of the liquid crystal display panel. Therefore, when the liquid crystal layer is formed in the liquid crystal display panel through a vacuum injection method, a part of the seal pattern must be opened to have a function of the liquid crystal injection hole.

In the dropping method, a liquid crystal is dropped and dispensed into a pixel portion of a first mother substrate having a large area in which a plurality of array substrates are arranged or a second mother substrate in which a plurality of color filter substrates are disposed using a dispenser, The liquid crystal layer is formed by uniformly distributing the liquid crystal through the entire pixel portion by the pressure for bonding the first and second mother substrates together.

Therefore, when the liquid crystal layer is formed on the liquid crystal display panel by dropping, the seal pattern should be formed in a closed pattern surrounding the outer edge of the pixel portion so as to prevent the liquid crystal from leaking to the outside of the pixel portion.

The dropping method can drop the liquid crystal in a short time compared to the vacuum injection method, and even when the liquid crystal display panel is enlarged, the liquid crystal layer can be formed very quickly.

In addition, since only the required amount of liquid crystal is dropped on the substrate, the price competitiveness of the liquid crystal display panel due to the disposal of expensive liquid crystal, such as a vacuum injection method, is prevented, thereby enhancing the price competitiveness of the product.

Unlike the vacuum injection method, the liquid crystal display panel to which the drop method is applied has a process of separating the unit liquid crystal panel from the large area mother substrate after the liquid crystal layer is formed.

Meanwhile, as described above, the present invention can be applied to a case in which the column spacer pattern is formed in a lattice form of several pixel units instead of one pixel unit, which will be described in detail through the following second embodiment.

6 is a plan view schematically illustrating an array substrate according to a second exemplary embodiment of the present invention.

As shown in the figure, a predetermined column spacer pattern 230 is formed in a predetermined region of the array substrate 210 to maintain a cell gap with the color filter substrate (not shown). The 230 is formed in a lattice form in units of pixels in the pixel unit 235.

As described above, the larger the liquid crystal display panel becomes, the larger the problem of gravity failure becomes. In this embodiment, the column spacer pattern 230 is formed in the pixel unit area in the lattice form to prevent the liquid crystal from tilting. To solve the problem of gravity failure.

In this case, the column spacer pattern 230 may be formed in an area covered by the black matrix of the color filter substrate (not shown), which is the upper substrate, to prevent a decrease in the aperture ratio of the liquid crystal display panel.

In this embodiment, the column spacer pattern 230 is formed on the gate line (not shown) and the data line (not shown) of the lower array substrate 210 corresponding to the upper black matrix area to have a lattice shape. For example, the present invention is not limited thereto, and the column spacer pattern 230 of the present invention may be formed only on the gate line.

In addition, the column spacer pattern 230 of the present embodiment is shown as a case of forming a closed lattice, for example, but the present invention is not limited thereto, and the column spacer pattern 230 is formed by using a SAM technique, and the lowering of the liquid crystal is prevented. It is also applicable to the case of forming a part of an open form simply by forming a pattern to prevent gravity failure by preventing.

Many details are set forth in the foregoing description but should be construed as illustrative of preferred embodiments rather than to limit the scope of the invention. Therefore, the invention should not be defined by the described embodiments, but should be defined by the claims and their equivalents.

As a result, the image quality of the liquid crystal display panel is improved.
