BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device including a triple structure column spacer having a function of preventing staining by cell gap holding and pressing, and a manufacturing method thereof.

In general, a liquid crystal display device is a display device that displays an image by using optical anisotropy and birefringence characteristics of a liquid crystal filled between two bonded substrates.

Hereinafter, a general configuration of a liquid crystal display device will be described with reference to FIG. 1.

1 is a view schematically showing a liquid crystal display according to the related art.

As shown in the drawing, a general color liquid crystal display 11 includes a color filter 7 including a black matrix 6 formed between a sub color filter 8 and each sub color filter 8, and the color filter ( The color filter substrate 5 having the common electrode 18 deposited thereon and the pixel region P are defined, and the pixel electrode 17 and the switching element T are formed in the pixel region. The liquid crystal 14 is filled between the array substrate 22 having the array wiring formed around the region P, and the color filter substrate 5 and the array substrate 22.

In the array substrate 22, a thin film transistor T, which is a switching element, is positioned in a matrix type, and a gate line 13 and a data line 15 passing through the plurality of thin film transistors T are formed. do.

In this case, the pixel area P is an area defined by the gate line 13 and the data line 15 crossing each other, and a transparent pixel electrode 17 is formed on the pixel area P as described above.

The pixel electrode 17 uses a transparent conductive metal having a relatively high transmittance of light, such as indium-tin-oxide (ITO).

The liquid crystal panel is completed by bonding the color filter substrate 5 and the array substrate 22 configured as described above with the liquid crystal layer 14 interposed therebetween, and the liquid crystal layer is formed of the color filter substrate 5. Positioned between the array substrates 22 and the surface is initially arranged by the rubbed alignment film.

In the above-described configuration, when a voltage is applied between the pixel electrode 17 and the common electrode 18, an electric field is generated in the longitudinal direction, and the liquid crystal molecules 14 are moved by the electric field, thereby changing the electric field. The image can be expressed by the light transmittance.

Although not shown in the above-described configuration, a spacer is formed between the array substrate 22 and the color filter substrate 5 to maintain a gap between the two substrates.

In the liquid crystal panel configured as described above, light leakage occurs when an external force such as pressing is applied from the outside.

Such light leakage is caused by the occurrence of slippage between the array substrate and the color filter substrate due to an external force, causing the liquid crystal panel to be warped.

That is, the rubbing directions of the array substrate and the color filter substrate are not parallel to each other in the bending direction of the liquid crystal panel. As a result, the liquid crystals adjacent to the substrate surface are arranged in parallel in the X direction, so that the overall arrangement is different from the initial state.

In such a case, the arrangement of the liquid crystals does not maintain the initial black state, and the light passing through the liquid crystal layer rotates while undergoing a retardation different from that of the normal portion, resulting in light leakage.

Therefore, a dual column spacer structure has been introduced as a method for solving such defects.

That is, when the columnar column spacer is configured, a so-called first column spacer having a function of maintaining a gap between the array substrate and the color filter substrate, and a second column spacer for preventing light leakage due to external force are formed. A structure for forming a dual column spacer (Dual Column Spacer) has been proposed.

This will be described below with reference to FIG. 2.

2 is an enlarged cross-sectional view illustrating a configuration of a liquid crystal display according to the related art.

As shown, the liquid crystal display (LCD) is composed of an array substrate (B1) and a color filter substrate (B2).

The array substrate B1 includes a thin film transistor T and array wirings 13 and 15 connected to the transparent insulating substrate 22.

In detail, the pixel region P including the switching region S and the storage region (not shown) are formed on the transparent first substrate 22, and the gate electrode 32 is formed in the switching region S. FIG. And a thin film transistor T including an active layer 34, a source electrode 36, and a drain electrode 38, and a transparent pixel electrode 17 in contact with the drain electrode is positioned in the pixel region P. .

On one side and the other side of the pixel region P, a gate line 13 in contact with the gate electrode 32 of the thin film transistor T and a data line 15 in contact with the source electrode 36 are provided. Located.

The color filter substrate is spaced apart from the array substrate B1 configured as described above, and the color filter substrate B2 includes a transparent second insulating substrate 5, color filters, and black matrices 7a and 7b. do.

In detail, the thin film transistor T and the gate wiring may be disposed on an opposite surface of the transparent second substrate 5 spaced apart from the transparent first substrate 22 and the liquid crystal layer (not shown). The black matrix 6 is formed corresponding to the data lines 13 and 15, and the color filters 7a and 7b are formed on the surface corresponding to the pixel area P. As shown in FIG.

The color filter sequentially uses red, green, and blue color filters (7a, 7b, not shown), and sequentially configures corresponding to each pixel (P), or the same color filter for pixels P adjacent to each other in the vertical direction. It may be configured as a stripe shape (stripe type) constituting a.

A transparent common electrode 18 is formed on the entire surface of the substrate 22 including the color filters 7a and 7b and the black matrix 6.

In this way, the first column spacer 20a functions to maintain a gap between the array substrate B1 and the color filter substrate B2, while the second column spacer 20b is a liquid crystal under an external pressure. When the panel is pressed, it serves to withstand the load, thereby minimizing the distortion of the liquid crystal, thereby preventing stains.

At this time, the distribution form of the first column spacer 20a and the second column spacer 20b will be described below with reference to the drawings.

The spacer 20b and the gap column spacer 20a are uniformly arranged.

In general, the pressed column spacer 20b has a higher density than the gap column spacer 20a and may be arranged as an example of FIG. 3.

That is, the pressed column spacer 20b is configured every 1/3 pixel in the horizontal direction and every pixel in the vertical direction, and the gap column spacer 20a is every 1/3 pixel in the horizontal direction and 1 / in the vertical direction. It consists of every five pixels.

According to the above-described constant arrangement, when the pressed column spacer 20b and the gap column spacer 20a are connected to each other with a line between the pixels P formed with a dashed line, a regular arrangement is performed so as to have a rhombus shape. have.

The above arrangement can be modified in various ways, as can be seen in the conventional configuration, by increasing the density of the pressed column spacer (20a), to prevent the flow of the liquid crystal, in particular, when the external pressure is applied to such external force It acts as a resistance component to prevent stains.

However, despite the above-described configuration, when the external load increases, the pressed column spacer 20b partially breaks or a problem of digging the color filter layers R, G, and B occurs. As a result, there is a problem that another type of stain (paint stain) occurs.

The present invention has been proposed for the purpose of solving the above problem.
