Description

TECHNICAL FIELD [0001] The present invention relates to a color filter substrate and a display device including the color filter substrate.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color filter substrate and a display device including the color filter substrate, and more particularly to a color filter substrate having a column spacer arrangement structure for reducing sensitivity to an external force, And to a display device capable of reducing degradation.

The liquid crystal display device is characterized in that it has a large contrast ratio, is suitable for moving picture display, and has low power consumption, and is used in various fields such as a notebook computer, a monitor, and a TV.

Liquid crystals are thin and long in molecular structure, have optical anisotropy, which has directionality in arrangement, and polarizing properties, in which the direction of molecular arrangement is changed according to their size when placed in an electric field. Liquid crystal displays use optical anisotropy and polarizability of liquid crystal, Lt; / RTI >

Generally, a display device includes a display panel in which a liquid crystal layer is interposed between a first substrate (e.g., a color filter substrate) and a second substrate (e.g., an array substrate).

On the other hand, a spacer is provided between the first substrate and the second substrate to maintain a constant gap between the two substrates.

The spacer is divided into a ball spacer and a column spacer according to the shape and arrangement method thereof. In the case of the ball spacer, there is a problem that it is difficult to keep the gap between the two substrates constant by uneven scattering. Recently, a column spacer which can be patterned in a desired shape in a specific position is preferred.

Generally, the column spacer is provided with a gap column spacer, which is provided so as to be in contact with both substrates, in order to maintain a constant distance between the color filter substrate and the array substrate, and a gap between the color filter substrate and the array substrate, And can be classified as a pressing column spacer provided so as to be in contact with both substrates at the time of polishing.

Generally, since the pressed column spacer is not fixed to the array substrate, it can move along the direction in which the external force is applied, but can return to the original position when the external force is removed.

However, when a relatively strong external force is applied locally, when the pressed column spacer contacts the array substrate, the alignment film provided on the array substrate may be damaged. As a result, the alignment of the liquid crystal in the liquid crystal layer or the twist angle There is a problem that light leakage may occur. In particular, this light leakage phenomenon may occur frequently when the display device is highly sensitive to external force.

Also, in the case of a display device having high sensitivity to an external force, the display panel can be assembled in a warped state by an external force applied at the time of assembly. In this case, a light leakage phenomenon may occur in the vicinity of the edge of the display area even if an external force is not applied continuously.

This light leakage phenomenon can be observed, in particular, as a foggy mist on a black image, and is referred to as a black uniformity defect. FIG. 1 shows a display screen of a display device in which the above-described black uniformity defect occurs.

At this time, by increasing the arrangement density of the column spacer, the sensitivity to the external force can be reduced, thereby improving the display quality.

However, when the arrangement density of the column spacer in the display area is to be increased, the area of the black matrix layer where the column spacer is disposed must also be widened, so that the resolution and the aperture ratio of the display area are reduced.

Accordingly, in recent years, attempts have been made to reduce the light leakage near the edge of the display area by disposing the column spacer in the non-display area. However, as the non-display area corresponding to the bezel of the display device is narrowed, there is a limit to the column spacer which can be arranged in the non-display area.

FIG. 2 is a schematic view of a color filter substrate provided in the region A of FIG. 1, and FIG. 3 is a perspective view illustrating an arrangement structure of the column spacer 12 provided in the non-display region NDA of FIG.

2 and 3, a display area DA and a non-display area NDA are defined on the substrate 10, and the black matrix layer 20 and the planarization layer 30 are sequentially stacked.

A color filter layer CF including a red color filter CF_R, a blue color filter CF_B and a green color filter CF_G is disposed in the pixel region in the display region DA, .

Here, the column spacer 11 is a gap column spacer or a pressed column spacer. The column spacer 11 is provided so as to be in contact with the array substrate in order to maintain a constant gap between the two substrates in a state where the color filter substrate and the array substrate are bonded, As shown in FIG.

In addition, the column spacers 11 can be disposed on the black matrix layer of the color filter substrate corresponding to the gate lines of the array substrate in consideration of various factors such as liquid crystal margin, pressure margin, process error, and aperture ratio.

On the other hand, a sealing member 13 for preventing leakage of the liquid crystal layer in a state where the color filter substrate and the array substrate are bonded to each other is provided at the outermost portion of the non-display area NDA, and a column spacer 12 .

In general, the column spacer 12 disposed in the non-display area NDA is provided as a pressed column spacer so that the flow of the liquid crystal in the liquid crystal layer is not lowered between the non-display area NDA and the display area DA.

3, the column spacer 12 is a cylindrical column spacer with a circular cross section, and is disposed along a plurality of rows and columns.

As described above, the non-display area corresponding to the bezel of the display device tends to be gradually narrowed, and accordingly, the number of the column spacers that can be disposed in the non-display area is limited.

However, as shown in Fig. 3, when considering the margin between the column spacers for the flow of the liquid crystal in the liquid crystal layer, it is difficult to increase the batch density of the cylindrical column spacers as much as possible. In addition, in the case of cylindrical column spacers, The total area of the column spacer contacting the substrate is not large enough to sufficiently alleviate the sensitivity to the external force.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a color filter substrate having a column spacer arrangement structure for reducing the sensitivity to an external force.

It is another object of the present invention to provide a color filter substrate capable of improving the arrangement density of column spacers without lowering the aperture ratio or expanding the non-display area in the display area.

It is another object of the present invention to provide a display device capable of preventing light leakage from occurring due to external force applied to the display panel due to external force applied during assembly.

According to an aspect of the present invention, there is provided a color filter substrate having improved arrangement density of column spacers in a non-display area by disposing a column spacer having a bar shape extending in a width direction or a non- Can be provided.

Further, according to the above example, a color filter substrate can be provided which can reduce the sensitivity to external force by increasing the total contact surface exposed to the arrangement density of the column spacers in the non-display area.

According to another aspect of the present invention, there is provided a color filter substrate in which a column spacer having a bar shape extending in a non-display region or a width direction in a non-display region is disposed, thereby reducing sensitivity to an external force, It is possible to provide a display device capable of improving the display quality.

The color filter substrate according to the present invention can increase the arrangement density of the column spacers in the non-display area and reduce the sensitivity to external force when applied to a display device.

Further, according to the present invention, even if the display device has a relatively narrow bezel area, the column spacer having a bar shape extending in the length direction or the width direction of the non-display area is provided in various patterns, It is possible to alleviate this bending.

According to the present invention, since the total area of the column spacer in contact with the array substrate can be increased compared with the arrangement density of the column spacer in the non-display area, light leakage occurs near the boundary between the non-display area and the display area Can be reduced.

The color filter layer CF includes alternately arranged red color filters CF_R, blue color filters CF_B and green color filters CF_G, and one color filter is located in one pixel region. Each pixel region becomes a sub-pixel SUB-PIXEL and three subpixels corresponding to the red color filter CF_R, the blue color filter CF_B and the green color filter CF_G form one pixel PIXEL .

The color filter layer CF includes a plurality of rows in which a plurality of red color filters CF_R, a blue color filter CF_B and a green color filter CF_G are alternately arranged, A cylindrical gap or compression spacer 150 is disposed. The spacer 150 positioned in the display area DA is provided to increase the supporting force between the color filter substrate and the array substrate in the display area DA.

FIG. 5 is a cross-sectional view of a display device according to an embodiment of the present invention, and is a cross-sectional view taken along the line B-B 'in FIG.

Referring to FIG. 5, a black matrix layer 110 is provided in a display area DA and a non-display area NDA defined in the first substrate 100 corresponding to the color filter substrate, and a black matrix layer 110 ) Is provided with an opening for exposing the pixel area in the display area.

A color filter layer CF including a red color filter CF_R, a blue color filter CF_B, and a green color filter CF_G corresponding to each sub-pixel is provided on a pixel region exposed through the opening, And a planarization layer 120 covering the color filter layer 110 and the color filter layer CF.

The second substrate 300 corresponding to the array substrate is opposed to the first substrate 100 and a thin film transistor Tr is formed in a display area DA of the second substrate 300 at a position where the gate line and the data line cross each other. . The upper surface of the thin film transistor Tr exposed through the opening disposed in the insulating layer 310 is connected to the pixel electrode 320.

The liquid crystal layer 200 is interposed between the first substrate 100 and the second substrate 300 and the first substrate 100 and the second substrate 300 are bonded to the outermost periphery of the non- A sealing member 140 for preventing leakage of the liquid crystal layer 300 is disposed.

The non-display area NDA can serve as a so-called bezel area because the black matrix layer 110 is entirely provided on the first substrate 100 with reference to the non-display area NDA. A planarization layer 120 is disposed on the black matrix layer 110 and a plurality of column spacers 130 are disposed on the planarization layer 120.

At this time, the column spacer 130 is formed in such a manner that not only the fluidity of the liquid crystal in the liquid crystal layer in the non-display area NDA but also the liquidity of the liquid crystal in the liquid crystal layer between the non-display area NDA and the display area DA The second substrate 300, or more precisely, the insulating layer 310 on the second substrate 300. In this case,

FIG. 6 is a plan view schematically showing one embodiment of the color filter substrate applied to FIG. 5, which corresponds to the area C in FIG. 7 is a perspective view schematically showing the arrangement structure of the column spacers provided in the non-display area NDA of FIG.

6 and 7, the column spacer 130 provided on the planarization layer 120 located in the non-display area NDA is spaced apart along the longitudinal direction L of the non-display area NDA by a predetermined length As shown in Fig.

At this time, since the column spacer 130 has a bar shape extending by a predetermined length along the longitudinal direction L of the non-display area NDA, the column spacer 130 has a square shape in which the ratio of the species x1 to the lateral y is different Top or cross-section.

The longitudinal direction of the column spacer 130 has a trapezoidal shape in which the width gradually decreases from the first substrate 100 toward the second substrate 300. The width x2 of the lower surface of the column spacer 130 contacting the first substrate 100 is smaller than the width x1 of the upper surface facing the second substrate 200. [

At this time, the adjacent column spacers 130 are preferably spaced apart from each other to increase the fluidity of the liquid crystal in the liquid crystal layer in the non-display area NDA, Is set to be narrower than the width (x2) of the lower surface of the column spacer 130, the arrangement density of the column spacer 130 in the non-display area NDA can be increased.

The column spacer 130 has a plurality of rows and a plurality of columns along the width direction W and the length direction L of the non-display area NDA in order to further increase the arrangement density in the non-display area NDA. .

Referring to the shape and arrangement of the column spacer 130 shown in FIGS. 6 and 7, the arrangement density in the non-display area NDA can be further increased as compared with the cylindrical column spacer shown in FIG. 3, It is possible to provide a strong supporting force in the area (NDA). Thus, the resistance to local external force applied near the boundary between the non-display area NDA and the display area DA can be improved and the sensitivity to external force can be reduced.

When the external force is applied, the upper surface of the column spacer 130 contacting the second substrate 300 has a rectangular shape as the gap between the first substrate 100 and the second substrate 300 becomes narrower The total area of the column spacers contacting the second substrate 300 can be increased compared with the arrangement density of the column spacers 130 in the non-display area NDA.

Accordingly, even when the narrow non-display area NDA is defined, it is possible to provide a stronger supporting force than the conventional cylindrical column spacer.

As described above, the display device according to an exemplary embodiment of the present invention has a non-display area NDA and a non-display area NDA through the shape and arrangement structure of the column spacer 130 provided in the non- And the boundary between the display area DA and the display area DA, thereby reducing the occurrence of light leakage near the edge of the display area DA.

8 and 9 are plan views schematically showing a color filter substrate according to another embodiment of the present invention. FIG. 10 is a schematic view showing a schematic arrangement of a column spacer and a subcolumn spacer provided in the non-display area NDA of FIG. Fig.

The liquid crystal molecules in the liquid crystal layer in the non-display area NDA or between the non-display area NDA and the display area DA can be prevented from being separated from each other when the spacing between the rows in which the plurality of column spacers 130 are arranged is excessively narrow. There is a possibility that the fluidity of the fluid may be lowered. Therefore, the rows and columns in which the plurality of column spacers 130 are disposed need to be disposed at a predetermined spacing distance.

8 to 10, at least one sub-column spacer 135 may be disposed at a spacing between a row and a row in which a plurality of column spacers 130 are disposed, Can be further improved.

Here, the sub-column spacer 135 may be a cylindrical sub-column spacer having a circular cross-section, or a bar-shaped sub-column spacer having a cross-section that is a quadrangle in which the cross-section is vertical and horizontal.

For example, as shown in FIG. 8, a plurality of cylindrical subcolumnar spacers 135 may be disposed between a row and a row in which a plurality of column spacers 130 are arranged, or a plurality of A sub-column spacer 135 having a bar shape between the row and the row in which the column spacer 130 is disposed can be disposed along the width direction of the non-display area NDA.

Although not shown separately, a sub column spacer 135 occupying a space smaller than the column spacer 130 is disposed between the column spacers 130 arranged in one row to form a sub column spacer 135 in the liquid crystal layer The fluidity of the liquid crystal can be improved.

FIG. 11 is a plan view schematically showing a color filter substrate according to another embodiment of the present invention, and FIG. 12 is a cross-sectional view schematically showing the arrangement structure of a column spacer and a subcolumn spacer provided in the non- It is a perspective view.

11 and 12, the sub column spacer 135, which is disposed at a spacing between the row and the row in which the plurality of column spacers 130 are arranged, is spaced apart from the boundary between the display area DA and the non-display area NDA As shown in FIG.

The arrangement density of the column spacer is drastically reduced with reference to the boundary between the non-display area NDA and the display area DA, and the light leakage phenomenon in the vicinity of the edge of the display area DA, Often it can happen.

At this time, in order to increase the arrangement density of the column spacers in the vicinity of the boundary between the non-display area NDA and the display area DA, the area of the non-display area NDA may be increased or the non- DA, which may cause problems such as an increase in the bezel area or a decrease in the aperture ratio.

Accordingly, according to one embodiment of the present invention, a part of the sub column spacer 135 disposed at the spacing between the row and the row where the plurality of column spacers 130 are arranged is divided into the non-display area NDA and the display area It is possible to improve the supporting force in the vicinity of the rim of the display area DA.

FIG. 13 is a cross-sectional view of a display device according to another embodiment of the present invention, taken along line B-B 'in FIG. 4. Fig. 14 is a plan view schematically showing another embodiment of the color filter substrate applied to Fig. 13, which corresponds to region C in Fig. 15 is a perspective view schematically showing the arrangement structure of column spacers provided in the non-display area NDA of FIG.

13 to 15, the column spacers 130 provided on the planarization layer 120 located in the non-display area NDA extend along the width direction W of the non-display area NDA to a predetermined length As shown in Fig.

At this time, the column spacer 130 has a bar shape extending by a predetermined length along the width direction W of the non-display area NDA, so that the column spacer 130 has a top surface or a cross section of a square having a different aspect ratio.

The column spacer 130 according to the embodiment is arranged in parallel with the width direction W of the non-display area NDA to improve the fluidity of the liquid crystal in the liquid crystal layer between the non-display area NDA and the display area DA Can be further improved. Accordingly, even if the arrangement density of the column spacer 130 in the non-display area NDA is increased, the possibility of the liquid crystal in the liquid crystal layer being lowered in fluidity can be reduced, and the display quality deteriorated due to the lowered liquidity of the liquid crystal in the liquid crystal layer Can be reduced.

16 is a plan view schematically showing a color filter substrate according to another embodiment of the present invention.

Referring to FIG. 16, at least one sub-column spacer 135 may be disposed between neighboring column spacers 130. Accordingly, a sub column spacer 135 occupying a space smaller than the column spacer 130 is disposed between the column spacers 130 to form a sub column spacer 135 in the non-display area NDA or the non-display area NDA and the display area DA, The liquidity of the liquid crystal in the liquid crystal layer can be further improved.

FIG. 17 is a plan view schematically showing a color filter substrate according to another embodiment of the present invention, and FIG. 18 is a perspective view schematically showing an arrangement structure of column spacers provided in the non-display area NDA of FIG.

By increasing the supporting force by the column spacer, it is possible to prevent the light leakage due to the warping of the display panel and reduce the sensitivity to the external force, thereby reducing the luminance variation due to the twist angle of the liquid crystal when the local external force is applied.

While the present invention has been particularly shown and described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is therefore to be understood that such changes and modifications are intended to be included within the scope of the present invention unless they depart from the scope of the present invention.
