Description
Technical Field
The invention relates to the field of liquid crystal display, in particular to a liquid crystal display device with specific spacer arrangement.
Background
Liquid crystal displays are popular as flat and ultra-thin display devices because of their advantages such as non-radiative, light and thin properties and power saving, and are widely used in various information, communication and consumer electronics products. Most of the liquid crystal display devices that are commonly used at present are constituted by a pair of substrates and a liquid crystal layer sealed in a gap therebetween; the substrates are oppositely arranged, and a spacer is arranged between the two substrates, the spacer plays a role in supporting, and a certain gap is kept between the substrates, so that a liquid crystal layer is sealed in the gap between the substrates to form the liquid crystal display device. In recent years, to improve the uniformity of the cell thickness of the lcd, the spacer in the gap is selected by replacing the conventional bead structure with a photo-lithographically processed pillar-shaped Photo Spacer (PS).
The spacer of the prior liquid crystal display comprises a main spacer (MPS) and an auxiliary spacer (SPS)
) The main spacer plays a role of supporting the two substrates between the two substrates; the auxiliary spacer only plays a supporting role under the condition that pressure is borne between the two substrates. The common main spacer and the auxiliary spacer are arranged in a spacing form, and the spacing structure supports the two substrates, so that the phenomenon of light leakage is avoided when the two substrates are pressed.
At present, in order to avoid the light leakage phenomenon which often occurs when the liquid crystal screen is squeezed, an outward expansion area is usually added in a spacer area; FIG. 1 is a schematic cross-sectional view of a prior art septum 101 and flared region 102, having three main configurations: A. the structure of a square main spacer and a circular outward-expanding area; B. the structure of the circular main shock insulator and the circular outward-expanding area; C. circular main spacer and square flaring zone. Based on the existing liquid crystal screen design mode, when the difference between the outward expansion areas of the main spacer and the auxiliary spacer is large, obvious regular dark spots appear on the liquid crystal screen, wherein the shapes of the regular dark spots are consistent with the shapes formed by the distribution positions of the main spacer, and thus the quality of the picture of the display screen is reduced.
Therefore, it is an urgent problem to be solved in the art to provide a scheme for improving the arrangement of the main spacers with regular dark spots or diagonal lines.

(1) according to the liquid crystal display device, the first spacers for supporting the array substrate and the color film substrate are alternately arranged in odd and even rows, and are alternately arranged at different pixel positions under the condition of the same arrangement of the second spacers, so that light leakage caused by the difference of local spacers can be reduced, the phenomenon of regular dark spots is weakened, and the dark spots are in a pasty state.
(2) According to the liquid crystal display device, when the second spacer is positioned between the two first spacers in the same pixel row, the light shielding film of the second spacer is set to be the same as the light shielding film of the first spacer in size, so that the difference of the light shielding films in the same pixel row can be reduced, light leakage caused by the difference of the light shielding films is reduced, and the condition that regular dark spots occur in the same pixel row is avoided.

Based on the above technical problem, the present application provides the following solutions.
As shown in fig. 3 and 4, fig. 3 is a schematic structural diagram of a liquid crystal display device provided in this embodiment; fig. 4 is a schematic diagram of the corresponding position of the first spacer on the array substrate applied to the liquid crystal display device in fig. 3 according to this embodiment. The liquid crystal display device includes: the array substrate 301 and the color filter substrate 302 are arranged opposite to each other, and the array substrate 301 and the color filter substrate 302 are arranged opposite to each other.
The liquid crystal display device of the present embodiment is configured such that the array substrate 301 and the color filter substrate 302 are disposed facing each other with a spacer kept at a predetermined gap, and then sealed with a sealant, and a liquid crystal composition is sealed in the gap formed between the array substrate 301 and the color filter substrate 302. In some alternative embodiments, a TFT substrate may be used as the array substrate 301.
The color filter substrate 302 plays a key role in displaying a color image, a voltage is applied to a pixel electrode corresponding to a red resistance unit of the color filter substrate 302 to cause a liquid crystal corresponding to the red resistance unit to deflect, so that light of a backlight source is transmitted through the liquid crystal and enters the red resistance unit to obtain red light, no voltage is applied to a pixel electrode corresponding to a green resistance unit and a pixel electrode corresponding to a blue resistance unit, and a user views a display panel to see a red picture.
The array substrate 301 includes a substrate and a pixel array on the substrate, and the array substrate 301 includes: the gate lines 311 extending transversely and longitudinally and the data lines 312 extending longitudinally and transversely on the array substrate 301 intersect with each other transversely and longitudinally. The gate lines 311 and the data lines 312 intersect to form pixel units 313 arranged in an array, and the pixel units 313 are transversely and sequentially arranged on the array substrate 301 as a red sub-pixel unit 314, a green sub-pixel unit 315 and a blue sub-pixel unit 316. Here, the arrangement order of the red sub-pixel unit, the green sub-pixel unit and the blue sub-pixel unit is not limited, and various possible arrangement orders of the sub-pixel units are within the scope of the present embodiment. It is not limited that the sub-pixel colors of the pixel unit 313 are red, green and blue, and the combination of sub-pixels of other colors can be used to arrange the first spacers alternately between the odd and even pixel rows and alternately between the sub-pixel columns, which is within the scope of the present embodiment.
The color filter substrate 302 includes a first spacer 321, a first end 322 of the first spacer 321 is fixed on the color filter substrate 302, a second end 323 of the first spacer 321 is in contact with the array substrate 301, and the first spacer 321 is used for maintaining a distance between the array substrate 301 and the color filter substrate 302.
In some optional embodiments, the first spacer 321 is provided in a columnar shape, and includes a pillar body located between the array substrate 301 and the color filter substrate 302 and side surfaces located at two sides of the pillar body, where the side surfaces of the first spacer 321 may be provided in different shapes. In other alternative embodiments, a light shielding film flare is also provided for the first spacer 321.
On the array substrate 301, the data lines 312 are obliquely arranged at an angle to a perpendicular line of the gate lines 311, and the gate lines are divided into odd gate lines 317 and even gate lines 318 according to positions. When the acute angle between the data line 312 and the gate line 311 is positive from the direction extending transversely (direction a in fig. 4) to the counterclockwise direction of the data line 312, the gate line is the odd gate line 317; an acute angle α between the data line 312 and the gate line 311 is from a direction (direction a) extending in the transverse direction to the even gate line 318 when the data line 312 is at a negative angle in the counterclockwise direction. The second end 323 of the first spacer is disposed at the crossing position 319 of the gate line 311 and the data line 312.
The data lines 312 are arranged in a multi-domain bent configuration according to the positional relationship between the odd gate lines 317 and the even gate lines 318 and the data lines 312. Through the arrangement of the multi-domain buckling structure, a pixel unit in the liquid crystal display device is divided into a plurality of domains, liquid crystal molecules in each domain deflect towards the respective domain direction under the voltage application state, and the liquid crystal molecule orientation in the same pixel unit is divided into a plurality of directions in such a way, so that the visual angles of all angles can be compensated, uniform display in all visual angle directions is realized, and the visual angle characteristics under different viewing angles can be effectively improved.
The red sub-pixel unit column and the green sub-pixel unit column which are adjacent to each other form a first interval pixel column 303; the adjacent green sub-pixel unit column and blue sub-pixel unit column form a second spaced pixel column 304.
The first alternate pixel column 303 crosses the odd gate line 317 to form a first location 305; the second spaced-apart pixel columns 304 intersect the even gate lines 318 to form second locations 306.
The second ends 323 of the first spacers in the first spaced pixel columns 303 are disposed at the first locations 305; the second ends 323 of the first spacers in the second spaced pixel columns 304 are disposed at the second locations 306.
As shown in fig. 3 and 5, fig. 5 is a schematic diagram of a corresponding position of a first spacer on an array substrate in another alternative liquid crystal display device provided in this embodiment, where the array substrate is applied to the liquid crystal display device in fig. 3. Unlike the embodiment of fig. 4, the array substrate shown in fig. 5 further includes: a third spaced pixel column 501 and a third location 502. The green sub-pixel unit column and the red sub-pixel unit column adjacent to each other form a third spaced pixel column 501. A third alternate pixel column 501 intersects the odd gate line 317 to form a third location 502; the second ends 323 of the first spacers in the third spaced pixel columns 501 are disposed at the third position 502.
The liquid crystal display device of the embodiment comprises pixel units distributed in an array mode, wherein the pixel units are composed of red sub-pixel units, green sub-pixel units and blue sub-pixel units. The red sub-pixel units, the green sub-pixel units and the blue sub-pixel units are sequentially and alternately arranged to form three intersection positions, namely, a position defined by the intersection of the red sub-pixel units and the green sub-pixel units with the gate lines, a position defined by the intersection of the green sub-pixel units and the blue sub-pixel units with the gate lines, and a position defined by the intersection of the blue sub-pixel units and the red sub-pixel units with the gate lines.
If the first spacer is only arranged at the position limited by the red sub-pixel unit, the green sub-pixel unit and the gate line, and the position limited by the green sub-pixel unit, the blue sub-pixel unit and the gate line. The first spacers at three crossing positions defined by the crossing of the blue sub-pixel unit, the red sub-pixel unit and the gate line are not uniformly distributed due to the lack of the first spacers, thereby causing the problem of regular dark spots. In the optional embodiment, the first spacers are arranged at the crossing positions of the data lines and the gate lines, so that odd and even rows of the first spacers on the pixel units are alternated, and the pixel positions are distributed in a staggered manner, thereby avoiding light leakage caused by the distribution difference of the first spacers and being beneficial to improving the problem of regular dark spots.
In some alternative embodiments, the first position 305 is disposed at a central position where the first spaced pixel column 303 intersects the odd gate line 317; the second position 306 is disposed at the center of the second spaced pixel column 304 intersecting the even gate line 318; the third position 502 is disposed at the center of the third alternate pixel column 501 and the odd gate line 317.
The crossing of the spaced pixel rows and the gate lines forms a crossing area which is larger than the second end of the first spacer, so that the second end of the first spacer can correspond to any position of the crossing area, which is inconvenient for accurately positioning the first spacer and causes uneven distribution of the first spacer in the whole liquid crystal display device. In the embodiment, the first spacer is arranged at the center of a crossing area formed by crossing the interval pixel rows and the gate lines, so that the first spacer is beneficial to ensuring accurate positioning, and the first spacer in the whole liquid crystal display device is uniformly distributed, thereby improving the problem of obvious regular dark spots on the liquid crystal screen.
In some alternative embodiments, the first location 305 and the third location 502 may be on the same odd gate line 317. In another alternative embodiment, the first location 305 is on a different odd gate line 317 than the third location 502. The first position 305 and the third position 502 are located at different gate line positions, so that the first position 305, the second position 306 and the third position 502 are arranged in a staggered manner at transverse row alternate and longitudinal column positions, which is beneficial to reducing the distribution difference of the first spacer in a local area of the liquid crystal display device and reducing the problem of obvious regular dark spots. Particularly, when the first position 305, the second position 306 and the third position 502 are continuous, if the first position 305 and the third position 502 are on the same gate line, the first position 305, the second position 306 and the third position 502 form a triangular arrangement, which causes that there is no first spacer 521 on one odd gate line corresponding to the area, and there is an uneven distribution phenomenon of two first spacers 521 on the other odd gate line, and here, the first position 305 and the third position 502 are set on different gate lines, which can avoid the uneven distribution phenomenon, and further reduce the problem of obvious regular dark spots.
In some optional embodiments, the orthographic projection shape of the first spacer 321 on the color filter substrate 302 is: one or more of round, square, oval, diamond, strip and drop can be combined freely.

Unlike the embodiment shown in fig. 5, on the array substrate shown in fig. 6, the first locations 305 are disposed at intersections of the first spaced pixel columns 303 and the odd-numbered gate lines 317; a second location 306 is disposed at the intersection of the second spaced pixel column 304 and the odd gate line 317; the third position 502 is disposed at the intersection of the third alternate pixel column 501 and the even gate line, and the first position 305 and the second position 306 are on different odd gate lines 317.
As shown in fig. 3 and 7, fig. 7 is a schematic diagram of a corresponding position of a first spacer on an array substrate in a further alternative liquid crystal display device provided in this embodiment, where the array substrate is applied to the liquid crystal display device in fig. 3.

As shown in fig. 3 and 8, fig. 8 is a schematic diagram of a corresponding position of a first spacer on an array substrate in a further alternative liquid crystal display device provided in this embodiment, where the array substrate is applied to the liquid crystal display device in fig. 3. Unlike the embodiment shown in fig. 5, the first locations 305 are disposed at the intersections of the first spaced pixel columns 303 and the odd gate lines 317; a second location 306 is disposed at the intersection of the second spaced-apart pixel column 304 and the even gate line 318; a third location 502 is disposed at the intersection of the third alternate pixel column 501 and the even gate line 318, and the second location 306 is at a different even gate line 318 than the third location 502.
As shown in fig. 3 and 9, fig. 9 is a schematic view of a corresponding position of a first spacer on an array substrate in a further alternative liquid crystal display device provided in this embodiment, where the array substrate is applied to the liquid crystal display device in fig. 3. Unlike the embodiment shown in fig. 5, the first location 305 is disposed at the intersection of the first alternate pixel column 303 and the even gate line 318; a second location 306 is disposed at the intersection of the second spaced-apart pixel column 304 and the even gate line 318; the third location 502 is disposed at the intersection of the third alternate pixel column 501 and the odd gate line 317, and the first location 305 and the second location 306 are at different even gate lines 318.
As shown in fig. 3 and 10, fig. 10 is a schematic view of a corresponding position of a first spacer on an array substrate in a further alternative liquid crystal display device provided in this embodiment, where the array substrate is applied to the liquid crystal display device in fig. 3. Unlike the embodiment shown in fig. 5, the first location 305 is disposed at the intersection of the first alternate pixel column 303 and the even gate line 318; a second bit 306 is disposed at the intersection of the second spaced pixel column 304 and the odd gate line 317; the third location 502 is disposed at the intersection of the third alternate pixel column 501 and the even gate line 318, and the first location 305 and the third location 502 are on different even gate lines 318.
Due to the multi-domain bent structure arranged in the liquid crystal display device, the phenomenon that odd gate lines 317 and even gate lines 318 alternate with each other occurs on the gate lines, and in addition, three different longitudinally arranged spaced pixel columns are adopted, so that 6 different crossing areas can be formed by crossing the gate lines and the spaced pixel columns, and the first spacers are respectively arranged in the 6 different crossing areas, so that the effect of improving regular dark spots or diagonal lines can be achieved.
As shown in fig. 3 and fig. 11, fig. 11 is a schematic diagram of a corresponding position of a first spacer on an array substrate in a further alternative liquid crystal display device provided in this embodiment, where the array substrate is applied to the liquid crystal display device in fig. 3. Unlike the embodiment shown in fig. 5, the first spacers 321 are first spacers in the same column, and the second ends 323 of the first spacers in the same column correspond to different gate line positions on the same pixel column. The first spacers in the same column at intervals greater than or equal to one pixel row are the first spacers in the same column, and the second ends 323 of the first spacers in the same column are located at the crossing positions of the odd-numbered and/or even-numbered gate lines and the data lines in the same pixel column.
The first spacers in the same row are spaced on the pixel rows and are still arranged according to the arrangement mode of the odd gate lines and the even gate lines, so that the first spacers in the same row are alternately arranged, light leakage is reduced, regular dark spots are weakened, paste is presented, and the display effect of the liquid crystal display device is improved.
As shown in fig. 12 and 13, fig. 12 is a schematic structural diagram of another alternative liquid crystal display device provided in this embodiment; fig. 13 is a schematic diagram of a corresponding position of a first spacer on an array substrate in a further alternative liquid crystal display device provided in this embodiment, where the array substrate is applied to the liquid crystal display device in fig. 12. Unlike the embodiment shown in fig. 3, the color filter substrate 302 of the liquid crystal display device shown in fig. 12 further includes: and a second spacer 324, a first end of the second spacer 324 being fixed on the color filter substrate 302, a height of the second spacer 324 being less than a height of the first spacer 321, a second end 325 of the second spacer not contacting the array substrate 301, and a second end 325 of the second spacer corresponding to a crossing position of the gate line and the data line. As shown in fig. 13, a second spacer light-shielding film 326 is disposed on the color film substrate 302 corresponding to the second spacer 325; a first spacer light shielding film 327 corresponding to the first spacer 321; the first spacer light shielding film 327 and the second spacer light shielding film 326 have different sizes.
Here, the height of the second spacer 324 is set to be smaller than the height of the first spacer 321, so that the second spacer 324 does not contact the array substrate 301 under normal conditions, and thus the problem of reducing the aperture ratio of pixels in the liquid crystal display device due to too many spacers can be avoided. Only when the array substrate 301 and the color filter substrate 302 are under the action of pressure, the second spacer 324 contacts the array substrate 301 and plays a role in supporting the array substrate 301 and the color filter substrate 302 under the action of pressure, so that the arrangement can ensure that when the array substrate 301 and the color filter substrate 302 are extruded, enough spacers provide a supporting function. The first spacer 321 and the second spacer 324 cooperate to reduce light leakage.
In other optional embodiments, the first spacer 321 and the second spacer 324 may have the same shape, the first spacer 321 and the second spacer 324 may have different shapes, and a projection area of the second spacer 324 on the color filter substrate 302 may be smaller than a projection area of the first spacer 321 on the color filter substrate 302. In this embodiment, the first spacer 321 and the second spacer 324 are disposed on the color filter substrate, in other optional embodiments, the first spacer 321 and the second spacer 324 may also be disposed on the array substrate, and one end of the first spacer 321 away from the array substrate is in contact with the color filter substrate, and one end of the second spacer 324 away from the array substrate is not in contact with the color filter substrate.
In some optional embodiments, the orthographic projection shape of the second spacer 324 on the color filter substrate 302 is: one or more of round, square, oval, diamond, strip and drop can be combined freely.
As shown in fig. 12 and 14, fig. 14 is a schematic view of a corresponding position of a first spacer on an array substrate in a further alternative liquid crystal display device provided in this embodiment, where the array substrate is applied to the liquid crystal display device in fig. 12.

If the light shielding films on the outer sides of the first spacer and the second spacer in the same pixel row have different sizes, the problem that the light shielding films are arranged unevenly locally and regular dark spots occur is caused. In this embodiment, the second spacer light-shielding film 326 of the second spacer is only changed to have the same size as the first spacer light-shielding film 327, so that the problem of regular dark spots caused by non-uniform light-shielding film arrangement can be avoided. Meanwhile, the arrangement of the second spacer is not changed in the embodiment, the effect of the second spacer in the liquid crystal display device is not affected, and the pixel aperture ratio of the liquid crystal display device is not reduced, so that the display effect of the liquid crystal display device is improved.
In some optional embodiments, the orthographic projection shapes of the first spacer light-shielding film 327 and the second spacer light-shielding film 326 on the color filter substrate 302 are as follows: one or more of round, square, oval, diamond, strip and drop can be combined freely.
In this embodiment, the orthographic projection shapes of the first spacer and the second spacer on the color filter substrate 302, and the orthographic projection shapes of the first spacer light-shielding film 327 and the second spacer light-shielding film 326 on the color filter substrate 302 are not limited. The arrangement of the first spacer, the second spacer, the spacer light-shielding film and the second spacer light-shielding film in the form of the first spacer supporting the array substrate and the color filter substrate arranged in the odd-numbered and even-numbered rows alternately is within the scope of the present embodiment. On the other hand, the orthographic projection shapes of the first spacer, the second spacer, the first spacer light-shielding film and the second spacer light-shielding film on the color film substrate are arranged according to one or more of the circular shape, the square shape, the oval shape, the diamond shape, the long strip shape and the drop shape in any combination mode, so that the manufacturing process of the first spacer, the second spacer, the first spacer light-shielding film and the second spacer light-shielding film is saved, and the stability of the first spacer, the second spacer, the first spacer light-shielding film and the second spacer light-shielding film can be improved.

(1) according to the liquid crystal display device, the first spacers for supporting the array substrate and the color film substrate are alternately arranged in odd and even rows, and are alternately arranged at different pixel positions under the condition of the same arrangement of the second spacers, so that light leakage caused by the difference of local spacers can be reduced, the phenomenon of regular dark spots is weakened, and the dark spots are in a pasty state.
(2) According to the liquid crystal display device, when the second spacer is positioned between the two first spacers in the same pixel row, the light shielding film of the second spacer is set to be the same as the light shielding film of the first spacer in size, so that the difference of the light shielding films in the same pixel row can be reduced, light leakage caused by the difference of the light shielding films is reduced, and the condition that regular dark spots occur in the same pixel row is avoided.
