Description

[0001] Liquid crystal display device [0002]

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 capable of improving an aperture ratio by omitting a black matrix and suppressing a tearing phenomenon at an outer portion of a display region.

Recently, liquid crystal display devices have been attracting attention as next generation advanced display devices with low power consumption, good portability, and high value-added.

In general, a liquid crystal display device is driven by using optical anisotropy and polarization properties of a liquid crystal. Since the liquid crystal has a long structure, it has a directionality in the arrangement of molecules, and the direction of the molecular arrangement can be controlled by artificially applying an electric field to the liquid crystal.

Therefore, when the molecular alignment direction of the liquid crystal is arbitrarily adjusted, the molecular arrangement of the liquid crystal is changed, and light is refracted in the molecular alignment direction of the liquid crystal by optical anisotropy, so that image information can be expressed.

At present, active matrix liquid crystal display devices (hereinafter, abbreviated as liquid crystal display devices) in which a thin film transistor and pixel electrodes connected to the thin film transistor are arranged in a matrix manner have been receiving the most attention because of their excellent resolution and video realization ability.

1 is a cross-sectional view of a general liquid crystal display device.

As shown in the figure, the general liquid crystal display device 1 has a structure in which the array substrate 10 and the color filter substrate 20 are attached to each other with the liquid crystal layer 30 interposed therebetween.

The lower array substrate 10 is provided with a plurality of gate wirings (not shown) and data wirings (not shown) arranged vertically and horizontally on the upper surface thereof to define a plurality of pixel regions P, A thin film transistor Tr is provided at one of the intersections of the pixel electrodes 18 and the pixel electrodes 18 provided in the pixel regions P in a one-to-one correspondence.

The color filter substrate 20 has a lattice which surrounds each pixel region P so as to cover the gate wiring (not shown), the data wiring (not shown) and the thin film transistor Tr, The first black matrix 24 having the shape of the first black matrix 24 and the second black matrix 25 surrounding the entire display area AA are provided. A color filter layer 26 including red, green and blue color filter patterns 26a, 26b and 26c which are sequentially and repeatedly arranged corresponding to the pixel region P is formed on the front surface of the color filter layer 26, A transparent common electrode 28 is provided.

The two substrates 10 and 20 are provided with a seal pattern 70 along the outermost edges of the non-display area NA in order to prevent leakage of the liquid crystal layer 30 interposed therebetween. 10 and 20) and the liquid crystal layer 30 are interposed between the upper and lower alignment films (not shown) for giving an initial alignment state of liquid crystal molecules.

A first polarizer (not shown) is attached to the outer surface of the array substrate 10 and a second polarizer (not shown) is attached to the outer surface of the color filter substrate 20.

In addition, back-light is provided on the outer surface of the array substrate 10 provided with the thin film transistor Tr, more precisely on the outer surface of the first polarizer plate (not shown) to supply light.

Therefore, on / off signals of the thin film transistor Tr are sequentially applied to the gate wiring (not shown) to scan the pixel electrodes 18 of the selected pixel region P to form data lines (not shown) The liquid crystal molecules constituting the liquid crystal layer 30 are driven by the vertical electric field between them, and various images can be displayed by the light transmittance change.

The conventional general liquid crystal display device 1 having such a configuration is completed by performing several mask processes. Since the mask process includes a unit process of exposure, development, etching, and strip, it takes a lot of time, A photoresist, which is a photosensitive material, is generally used to increase the manufacturing cost.

Therefore, in recent years, efforts have been made to reduce the manufacturing cost of the liquid crystal display device and thereby reduce the number of mask processes.

As an effort to reduce such a mask process, attempts have been made to reduce the number of mask processes and further improve the aperture ratio by eliminating the black matrix provided on the color filter substrate.

However, when the black matrix provided on the color filter substrate of the liquid crystal display device, particularly the second black matrix surrounding the display area, is removed, light leakage occurs at the outermost edge of the display area to degrade the display quality of the liquid crystal display It is a fact that we are doing.

DISCLOSURE OF THE INVENTION It is an object of the present invention to solve such a problem of the conventional liquid crystal display device, and it is an object of the present invention to provide a liquid crystal display device capable of suppressing light leakage at the edge portion of a display region even if a black matrix is removed, And a liquid crystal display device capable of reducing the number of display pixels.

In addition, there is an effect that the aperture ratio is improved by omitting the black matrix for framing the pixel region on the color filter substrate.

In addition, since the outer column spacer is formed to cover the light leakage prevention pattern with a width larger than that of the light transmission prevention pattern, the expansion coefficient between the protection layer and the light transmission prevention pattern, There is an effect of suppressing lifting which occurs due to the presence of the liquid.

Further, at least one color pattern having any one of red, green, and blue colors is formed in the non-display area, thereby further preventing light leakage at the outermost part of the display area.

In addition, since the common electrode and the pixel electrode in the form of a bar are formed in a line-symmetrical structure in which the data lines and the pixel electrodes are vertically folded in each pixel region, a dual domain is implemented to suppress the chrominance due to the change of the viewing angle .

At this time, first and second patterns 121a and 121b made of the same material as the semiconductor layer 120 are formed under the data line 130, the data link line (not shown) and the data pad electrode (not shown) The semiconductor dummy pattern 121 is formed due to the manufacturing process and can be omitted.

A source electrode 133 branched from the data line 130 is formed on the semiconductor layer 120 in the switching region TrA so that the drain electrode 136 is spaced apart from the source electrode 133. [ Respectively. At this time, the source electrode 133 and the drain electrode 136 are in contact with the ohmic contact layer 120b which are separated from each other.

The drain electrode 136 is formed in the storage region (not shown) corresponding to the first storage electrode 110 above the gate insulating layer 118 to form a second storage electrode 138. At this time, the first storage electrode 110, the gate insulating layer 118, and the second storage electrode 138, which are sequentially stacked in the storage region StgA, form a storage capacitor StgC.

Next, the data wiring 130, the source and drain electrodes 133 and 136, the second storage electrode 138, and the data link wiring (not shown) provided in the non-display area NA, which are provided in the display area AA, A first passivation layer 140 made of an inorganic insulating material such as silicon oxide (SiO ₂ ) or silicon nitride (SiNx) is formed on the entire surface of the substrate 102.

Next, the gate lines (not shown) and the data lines 130 are formed on the first passivation layer 140 in the display area AA corresponding to the pixel areas P, The color filter layer 150 having the shape in which the color filter patterns 150a, 150b, and 150c of the color filter layers 150a, 150b, and 150c are sequentially formed is formed.

However, the color filter layer 150 is not shown in FIG. 4 (the liquid crystal display device according to the first modification of the embodiment of the present invention Green and blue color filter patterns 150a and 150b constituting the color filter layer 150. The color filter layer 150 is formed of a transparent conductive material such as glass, And 150c may be formed in the non-display area NA as well.

This is because the color filter pattern 151 itself is an element for suppressing the transmission of light, so that the color filter pattern 151 is provided in the non-display area NA so as to prevent the light leakage.

At this time, the color filter pattern 151 provided in the non-display area NA may have a monolayer single layer structure, or the color filter pattern 151 (not shown) of two colors may be formed in a superimposed manner. In this case, the color filter pattern 151 is not formed for the pad portion PA having the gate pad electrode 117 and the data pad electrode (not shown) in the non-display area NA.

Next, referring to FIGS. 2 and 3, on the entire surface of the substrate 102 over the color filter layer 150 of the display area and the first passivation layer 140 of the non-display area NA, An organic film 155 made of photo acryl which is a material having a dielectric constant is formed.

The formation of the organic film 155 from a photo acryl having low dielectric constant characteristics is performed by overlapping the data line 130 and the shield pattern 175 formed on the uppermost common electrode 116 And minimizes the influence of the undesired electric field generated by the data line 130 and the outermost common electrode 116 formed in the periphery of the data line 130. In addition,

In addition, since the photo acryl has a negative type photosensitive characteristic that is left in a developing state upon receiving light, when a contact hole or the like is formed on the lower part of the manufacturing process, a separate strip process is not performed This has the advantage of simplifying the manufacturing process.

In addition, in each pixel region P, the color filter layer 150, the first passivation layer 140, and the gate electrode 150, which are provided below the organic layer 155, The insulating film 118 is provided with a first common contact hole (not shown) exposing one end of the outermost common electrode 116. The organic film 155, the color filter layer 150, A drain contact hole 157 for exposing the drain electrode 136 and more precisely the second storage electrode 138 extending from the drain electrode 136 is formed.

In the pad portion PA of the non-display region NA, the organic film 155, the first passivation layer 140, and the gate insulating film 118 are formed with the gate pad electrode 117, A gate pad contact hole 158 and a second common contact hole are formed in the organic layer 155 and the first passivation layer 140, And a data pad contact hole (not shown) for exposing a pad electrode (not shown).

Next, the organic layer 155 is formed on the organic layer 155 including the drain contact hole 157, the first and second common contact holes (not shown), the gate pad contact hole 158, and the data pad contact hole (not shown) The display area AA may be formed of any one of opaque low resistance metal materials such as molybdenum, moly titanium (MoTi), and copper (Cu) to form a single layer structure, A plurality of central common electrodes 173 and pixel electrodes 170 having a bar shape alternating with each other are formed for each pixel region P.

At this time, the pixel electrode 170, the central common electrode 173, and the outermost common electrode 116 may have a linear bar shape in each pixel region P, P may have a bar shape that is symmetrically deflected with respect to a central portion thereof.

In the case where the pixel electrode 170 and the common electrodes 116 and 173 are formed in a bar shape symmetrically bent in each pixel region P, each pixel region P has a double domain, And has an effect of suppressing the generation of color difference due to the change.

In this case, the plurality of bar-shaped pixel electrodes 170 are connected to one end of each pixel region P by a first auxiliary pattern 174, The pattern 174 is connected to the second storage electrode 138 through the drain contact hole 157.

The bar-shaped central common electrode 173 is also in contact with the outermost common electrode 116 through a first common contact hole (not shown) provided in each pixel region P to be.

At this time, in order to prevent light leakage around each pixel region P, the data line 130 and the outermost common electrode (not shown) adjacent to the data line 130 are formed on the organic layer 155, 116, and a shield pattern 175 is formed. The shield pattern 175 is formed so as to overlap with the gate wiring (not shown) and the common wiring (not shown) adjacent thereto, so that the shield pattern 175 substantially forms a lattice in the display area AA.

1) of the conventional liquid crystal display device (1 of FIG. 1) by overlapping the border area of each pixel region P, (24 in Fig. 1).

In another embodiment of the present invention, the non-display area NA is made of the same metal material having the pixel electrode 170 and the central common electrode 173 formed thereon, ), A spacing between the gate link wiring lines 115, and a spacing between data link wiring lines (not shown), and a light leakage preventing pattern 178 is formed. The light leakage prevention pattern 178 may be integrally formed in the non-display area NA or divided into a plurality of light emission preventing patterns 178.

In the drawing, the light leakage prevention pattern 178 is formed by dividing a plurality of the light transmission prevention patterns 178 into one.

The reason why the light leakage prevention pattern 178 is formed in the non-display area NA is to prevent light leakage in the outer area of the display area.

When the light leakage preventing patterns 178 are divided into a plurality of portions, the light leakage preventing patterns 178 are spaced apart from each other by the gap between the gate link wirings 117 provided below the light leakage preventing patterns 178, or between the static preventing means (not shown) (Not shown) and a data link wiring (not shown), an anti-static unit (not shown), and the like in addition to the gate link wiring 115, the data link wiring Thereby blocking light emitted from the light source.

The pad PA of the non-display area NA is provided with a gate auxiliary pad electrode 179 in contact with the gate pad electrode 117 through the gate pad contact hole 158, (Not shown) through a pad contact hole (not shown) and a data-assist pad electrode (not shown) in contact with the data pad electrode (not shown) through the second common contact hole (Not shown) and is provided with a common auxiliary pad electrode (not shown).

A plurality of column spacers 188 and 189 having a columnar shape and made of a transparent organic material or black resin are disposed on the shelf pattern 175 corresponding to the boundary of the pixel region P of the display area AA, Are formed at regular intervals. Wherein the plurality of column spacers 188 and 189 have a gap column spacer 188 having a first height and an end of which contacts the opposing substrate 181 and a second height lower than the first height, And a pressing column spacer 189 for suppressing bending or crushing of the gap column spacer 188 when the gap column spacer 188 is formed.

In addition to the column spacers 188 and 189, a first outer column spacer (not shown) having a columnar shape with a first height equal to the gap column spacer 188 in a column shape corresponding to the non-display area NA And a second outer column spacer 190 having a second height equal to that of the pressed column spacer 189 so as to completely cover the light leakage prevention pattern 178 having the patterned shape, Is formed.

When the column spacer 188 or 189 and the outer column spacer 190 (not shown) are made of black resin, the second outer column spacer 190 may be formed of the light- And serves as a black matrix for further shielding the light leakage at the outermost periphery of the display area AA together with the display area 178.

The second outer column spacer 190 is positioned outside the light leakage prevention pattern 178 located at the outermost one of the plurality of light leakage preventing patterns 178 having the patterned shape, Shielding pattern 178 and is formed such that its end is in contact with the organic film 155.

According to the configuration of the second outer column spacer 190, the patterned light leakage prevention pattern 178 has a shape in which both ends (or side ends) of the patterned light leakage preventing pattern 178 are covered with the second outer column spacer 190 It is possible to prevent the end of the light leakage prevention pattern 178 from being lifted or tore away from the organic layer 155 even if the heat treatment process is performed.

The lifting and tearing phenomenon of the light leakage prevention pattern 178 will be described in more detail.

In the manufacturing process of the array substrate 102, the heat treatment process is performed several times. In particular, after forming the light leakage prevention pattern 178, the first alignment layer (not shown) is formed at least after the first alignment layer It is exposed to a temperature of 200 DEG C or higher.

In this case, the bonding strength of the organic material, more precisely, the light shielding pattern 178 with the organic film 155 made of photo-acryl is weak and the thermal expansion coefficient according to the temperature rise is different. A relatively large stress is generated by having an area which is several times to several hundred times larger than an element provided in the region.

In this case, particularly, when the end of the light leakage prevention pattern 178 is exposed to the outside of the second outermost column spacer 190, the lifting and breaking phenomenon occurs.

The liquid crystal display device 100 according to an embodiment of the present invention includes a light shielding pattern 178 provided on a non-display area NA and a light shielding pattern 178 disposed on an upper portion thereof, In order to prevent lifting and tearing of the second outermost column spacer 190 located in the second outermost column spacer 190, the light leakage preventing pattern 178 is preferably divided into a plurality of segments, The contact area between the organic film 190 and the organic film 155 is widened, thereby suppressing the pull-in and pull-out failure.

At this time, the plurality of light leakage preventing patterns 178 are formed so as to overlap the gap between the gate link wirings 115 provided below, between the static electricity prevention means (not shown) and the data link wirings (not shown) It is possible to suppress the occurrence of light leakage at the outermost periphery of the display area AA.

The second outermost column spacer 190 may be formed as a single unit in the drawing. Alternatively, the second outermost column spacer 190 may be formed as a non-display portion of the liquid crystal display device according to the second modification of the embodiment of the present invention The second outermost column spacer 190 may also be divided into a plurality of segments, as shown in FIG. 5B. In the first outermost column spacer 190, , Both ends of which are located outside the light leakage prevention pattern 178, thereby being in contact with the organic film 155.

2 and 3, a columnar column spacer 188, 189 and a first alignment layer (not shown) are formed on the entire surface of the display area AA over the pixel electrode 170 and the central common electrode 173, Is provided.

On the other hand, an opposing substrate 181 having a second alignment film (not shown) formed on its inner surface corresponding to the array substrate 102 having such a configuration is located.

At this time, the liquid crystal layer 195 is resumed between the array substrate 102 and the counter substrate 181, and the ends of the gap column spacer 188 and the first outer column spacer (not shown) (Not shown) of the liquid crystal display device 100 according to the embodiment of the present invention.

Although not shown in the drawing, the non-display area NA is formed with an adhesive agent (not shown) in the form of surrounding the liquid crystal layer 195 so that the array substrate 102 and the counter substrate 181 are adhered to each other, A seal pattern 197 serving as a seal is further provided.

In the liquid crystal display 100 according to the embodiment of the present invention, the color filter layer 150 is provided on the array substrate 102 without a black matrix, thereby forming a color filter on TFT (COT) structure without a black matrix .

Meanwhile, the liquid crystal display device 100 according to the embodiment of the present invention having such a configuration does not form a black matrix, so that a single mask process for forming a black matrix can be omitted, thereby simplifying the process and reducing the manufacturing cost And further, there is an effect that the aperture ratio is improved by omitting the black matrix for framing the pixel region in consideration of the adhesion margin on the color filter substrate.

The non-display area NA surrounds the display area AA and is formed as an integral type or a plurality of divided parts. The light-prevention pattern is made of a metal material in the non-display area NA, Region, the light leakage can be prevented as well as these components.

In addition, since the outer column spacer is formed to have a width greater than that of the light leakage prevention pattern 178 to contact both ends of the light leakage prevention pattern 178 with the organic layer, There is an effect of suppressing the erroneous lifting and slitting failure caused by the difference in expansion coefficient between the organic film 155 of the organic material in which the pattern 178 is formed and the light leakage prevention pattern 178.
