The invention provides a color film substrate 100.
Referring to fig. 1 to 6, a color film substrate 100 according to the present invention includes: a base substrate 10; the black matrix layer 20 is arranged on one surface of the substrate base plate 10 and is provided with a plurality of light-transmitting areas 22 for arranging color light resistors 21; and the spacer 30 is arranged on one side of the black matrix layer 20, which is far away from the substrate base plate 10, and the spacer 30 extends along the periphery of the light-transmitting area 22 and separates two adjacent light-transmitting areas 22.
In an embodiment of the present application, the substrate base plate 10 may also be bendable or foldable. The substrate 10 may be made of a glass substrate or other light-transmitting structure.
The spacer 30 of the present invention is disposed in a display Area (Active Area), which is an Area where the substrate can display an image, and may be disposed in a middle Area of the substrate. The non-display area refers to an area which can not display a display image, and is generally arranged around the display area, and circuit wiring and other driving electronic components are arranged in the non-display area.
According to the technical scheme, the black matrix layer 20 is arranged on the substrate base plate 10, the light-transmitting areas 22 for placing the color photoresist 21 are arranged on the black matrix layer 20, the spacers 30 are further arranged on one side, away from the substrate base plate 10, of the black matrix layer 20, the spacers 30 extend along the peripheries of the light-transmitting areas 22, so that the adjacent light-transmitting areas 22 are separated, after the color film base plate 100 and the array base plate 200 are combined into a box and the liquid crystal 300 is injected, each light-transmitting area 22 can enter a certain amount of liquid crystal 300, and as each light-transmitting area 22 is separated, the liquid crystal 300 located in the adjacent light-transmitting areas 22 cannot be influenced by intermolecular acting force, so that the influence of the force of the liquid crystal 300 between pixels is avoided, and the display effect is guaranteed. Thus, the technical scheme of the invention can avoid mutual interference of the liquid crystals 300 corresponding to the adjacent pixels, thereby ensuring the display effect.
The black matrix layer 20 may be a chromium-based material or a resin-based material, and is formed on the base substrate 10 by patterning. In order to facilitate the control of the deflection of the liquid crystal 300, the color film substrate 100 and the array substrate 200 are further provided with ITO conductive films, and ITO is an abbreviation of Indium Tin Oxides. As nano indium tin metal oxide, it has good conductivity and transparency, and can cut off electron radiation, ultraviolet rays and far infrared rays harmful to human body. Therefore, indium tin oxide is generally sprayed on glass, plastic and electronic display panels to serve as a transparent conductive film while reducing electron radiation and ultraviolet and infrared rays harmful to the human body.
The surface of the conductive layer facing away from the black matrix layer 20 is further provided with an alignment film (alignment film), which is a thin film having straight scratches and functions to guide the alignment direction of the molecules of the liquid crystal 300. For example, a parallel groove is printed on the glass substrate coated with a transparent conductive film (ITO) by using PI coating liquid and a roller (roller), and the liquid crystal 300 can be horizontally laid in the groove along the direction of the groove, so as to achieve the purpose of arranging the liquid crystal 300 in the same direction. The material of the alignment film needs to have good light transmittance; must be present or partially ionized for ionization; having a covalent or partially covalent linkage; amorphous and good lattice structure.
It should be noted that the solution of the embodiment of the present application does not completely surround one pixel (the light-transmitting region 22), and at least one opening is provided for injecting the liquid crystal 300 after the cell.
The color photoresist 21 in the technical solution of the present invention can also be a blue photoresist layer, a red photoresist layer, a green photoresist layer or a white photoresist layer. It can be understood that the technical solution of the present invention can ensure that the display effect in the display area meets the required requirements, but does not limit the color arrangement and the number of the light blocking layers, that is, the blue light blocking layer, the red light blocking layer, the green light blocking layer or the white light blocking layer in the technical solution of the present invention may also be color layers of other colors, so that the display panel 1000 can meet other different display requirements. Other different combinations of the color-resisting layers are also within the protection scope of the invention.
Referring to fig. 5 and 6, in an embodiment of the present application, the black matrix layer 20 is defined to have a first direction and a second direction perpendicular to each other, the black matrix layer 20 has a plurality of light-transmitting regions 22 arranged along the first direction and the second direction, the spacers 30 are arranged in an elongated shape and extend along the first direction, and separate two adjacent light-transmitting regions 22 arranged at intervals along the second direction;
alternatively, the spacer 30 is in a long strip shape and extends along the second direction to separate two adjacent light-transmitting regions 22 arranged at intervals along the first direction.
When the outline of the black matrix layer 20 is rectangular, the first direction is the width direction of the black matrix layer 20, and the second direction is the length direction of the black matrix layer 20, at this time, the plurality of light-transmitting regions 22 are arranged along the length direction and arranged along the width direction. When the outer contour of the black matrix is circular, the first direction is a direction with any diameter, and the second direction is a direction perpendicular to the diameter.
In this embodiment, the spacer 30 is configured to be a long strip, on one hand, a plurality of pixels can be simultaneously separated, and the efficiency of separating the pixels is improved, and on the other hand, the long strip spacer 30 can have a larger contact area with the array substrate 200, so that the array substrate 200 can be better supported. By providing the spacers 30 extending in the transverse direction, the liquid crystal 300 corresponding to the light-transmitting regions 22 (pixels) arranged in the longitudinal direction is prevented from being affected by intermolecular forces of the adjacent liquid crystals 300 during operation, and the effect of the display panel 1000 is ensured. The conventional pixel unit arrangement forms the liquid crystal 300 with the acting force mainly from the longitudinal direction, so the arrangement of the transverse strip-shaped spacer 30 can better ensure the effect of the display panel 1000. By providing the spacers 30 extending in the longitudinal direction, the liquid crystal 300 corresponding to the light-transmitting regions 22 (pixels) arranged in the transverse direction is prevented from being affected by intermolecular forces of the adjacent liquid crystals 300 during operation, and the effect of the display panel 1000 is ensured. The acting force between the liquid crystals 300 formed by arranging the pixel units of the 3-D three-dimensional transistor adopting the tri-gate design mainly comes from the transverse direction, so the effect of the display panel 1000 can be better ensured by arranging the longitudinal strip-shaped spacer 30.
In some embodiments of the present invention, the material of the spacer 30 includes an insulating material. The insulating material can effectively shield the fringe electric field between adjacent pixels, thereby further ensuring that the liquid crystal 300 corresponding to each light-transmitting region 22 (pixel) is not affected by external force or electric field, and improving the display effect. Also, even if the pixels are smaller, the liquid crystals 300 between the adjacent pixels do not affect each other. Specifically, the spacer 30 may be made of acrylic resin, which has a low dielectric constant, so that the dielectric has a low relative ability to store electrostatic energy in an electric field, thereby preventing the generation of the electric field and improving the display effect.
The section outline of the spacer 30 can be rectangular, so that a larger contact area can be ensured on the side of the array substrate 200, the supporting effect is improved, and the rectangular arrangement can ensure that the spacer 30 has higher elastic recovery rate and external pressure deformation bearing capacity; no pollution is caused to the liquid crystal 300; the spacers 30 facilitate control of the density thereof, and make the film thickness uniformity more excellent. Or the spacer is arranged in a circular shape, so that the spacer can reduce the scratch caused by friction to the liquid crystal 300 in the vibration process, has higher elastic recovery rate and external pressure deformation bearing capacity, and is convenient to support the display area; or be the toper setting, so set up the holding surface great to promote the support effect.
Referring to fig. 6, in some embodiments of the present disclosure, the spacer 30 includes a first section 31 extending along the first direction and a second section 32 extending along the second direction, the first section 31 separates two adjacent light-transmitting regions 22 arranged at intervals along the second direction, and the second section 32 separates two adjacent light-transmitting regions 22 arranged at intervals along the first direction. The spacer 30 of the present embodiment includes the first section 31 and the second section 32 extending along different directions, so that the spacer 30 further separates the space of the liquid crystal 300 corresponding to the light-transmitting area 22 (pixel), and the liquid crystal 300 can be prevented from being affected by the liquid crystal 300 corresponding to the adjacent light-transmitting area 22 (pixel) in multiple directions, thereby greatly improving the display effect of the display panel 1000.
Referring to fig. 1 to 6, in some embodiments of the present application, each of the first segment 31 and the second segment 32 is provided in plurality, and the first segment 31 and the second segment 32 are sequentially connected end to form the spacer 30. The spacers 30 in this embodiment are substantially wave-shaped, and the plurality of light-transmitting regions 22 are separated by the plurality of first sections 31 and the plurality of second sections 32, so as to prevent the liquid crystals 300 corresponding to the adjacent light-transmitting regions 22 from affecting each other. In one embodiment, a first section 31 and a second section 32 are equal in length, thereby facilitating formation of uniform spacers 30 and facilitating support of the array substrate 200 by the spacers 30.

In this embodiment, by providing the plurality of first segments 31 and the plurality of second segments 32, the liquid crystal 300 can be prevented from being affected by the liquid crystal 300 corresponding to the adjacent light-transmitting regions 22 (pixels) in a plurality of directions, thereby greatly improving the display effect of the display panel 1000, and since the portions of the first segments 31 and the portions of the second segments 32 are arranged at intervals, when the liquid crystal 300 is injected into the cell, the liquid crystal 300 has more flowing spaces, thereby improving the injection efficiency of the liquid crystal 300. It is understood that the first segment 31 and the second segment 32 in this embodiment may be unequal in length, thereby creating a gap for the flow of the liquid crystal 300.
Referring to fig. 1 to 6, in some embodiments of the present disclosure, the number of the spacers 30 is multiple, and the spacers 30 are uniformly distributed on the black matrix layer 20.

It should be noted that the spacers 30 in this embodiment may be longitudinally long, transversely long, wavy, and any combination of the spacers 30 having the first section 31 and the second section 32 that are spaced from each other, and one, two, three, or four of the spacers 30 may be selected, and even the spacers 30 with different cross-sectional profiles (such as the rectangular, circular, and the like) may be combined, which is within the scope of the present invention.
Referring to fig. 7, the present invention further provides a manufacturing method of the color filter substrate 100, where the manufacturing method of the color filter substrate 100 is used to manufacture the color filter substrate 100 as described above, and the manufacturing method of the color filter substrate 100 includes the following steps:
step S10, providing a base substrate 10, and forming a black matrix layer 20 on the base substrate 10; it is understood that the black matrix layer 20 is made of one of an organic photoresist, an opaque metal, a metal oxide and a nitride, and can block light or reflect light back; when the black matrix layer 20 is an organic photoresist, the black matrix layer 20 may be formed by using techniques such as a dispenser, screen printing, nozzle printing, ink jet printing, and the like; when the black matrix layer 20 is made of metal or metal oxide, the black matrix layer 20 may be formed by using a thermal evaporation process, a magnetron sputtering process, a vapor deposition process, or the like; when the black matrix layer 20 is made of metal or metal oxide, the black matrix layer 20 may be formed by using a thermal evaporation process, a magnetron sputtering process, a vapor deposition process, or the like.
Step S20, etching the black matrix layer 20 to form a plurality of light-transmitting regions 22 for disposing the color resists 21; in this embodiment, a conventional manufacturing method is adopted, the black matrix layer 20 is exposed to light, the portions that need to be left are cured, and then the uncured portions are removed by wet etching or dry etching, so as to form a plurality of light-transmitting regions 22 for disposing the color resists 21. After this step, a color photoresist 21 is formed in the light-transmitting region 22 by the same method, i.e., photoresist coating, exposure, development, and etching.
In step S30, spacers 30 are formed on the surface of the black matrix layer 20 facing away from the substrate 10 to separate the adjacent light-transmitting regions 22. The spacer 30 in this embodiment may specifically be formed by:
step S31a, coating a photoresist layer on the surface of the black matrix layer 20 away from the base substrate 10;
step S32a, providing a mask, and exposing the mask corresponding to the photoresist layer;
step S33a, developing the exposed photoresist layer, and removing the undeveloped photoresist layer;
after coating the photoresist layer, vacuum drying the black matrix layer 20 coated with the photoresist layer; removing the edge photoresist of the dried black matrix layer 20, and performing baking and cooling; the black matrix layer 20 is exposed by a mask, wherein the mask at the periphery of the transparent region 22 has a larger transmittance. Alternatively, the spacer 30 having a large thickness in the height direction can be manufactured by reducing the partial ultraviolet transmittance by using a semi-permeable film of a Tone Mask (Tone Mask) or diffraction of light so that the light transmission at the periphery of the light-transmitting region 22 is bright and the light-blocking layer at the periphery of the light-transmitting region 22 is cured more because the light transmission amount at the periphery of the light-transmitting region 22 is large. The exposed photoresist layer is then developed, etched, and finally removed to obtain the spacers 30 separating adjacent light-transmitting regions 22.
In some embodiments, step S30 further includes:
step S31b, coating a photoresist layer on the surface of the black matrix layer 20 away from the base substrate 10; the photoresist layer in this embodiment may be a low-viscosity liquid polymer photoresist that is sensitive to ultraviolet light, and thus may be cured after ultraviolet irradiation, and further obtain a desired structure.
Step S32b, providing a light-transmitting nano pattern template, and pressing the pattern of the light-transmitting nano pattern template into the photoresist layer; the manufacturing method in the embodiment is suitable for fine products with high resolution or small pixel size, and because the pixel is small and the required pattern cannot be obtained directly through an exposure means, a light-transmitting nano pattern template can be manufactured in advance according to the requirement, for example, a longitudinal long-strip-shaped spacer 30 needs to be manufactured, the light-transmitting nano pattern template with a long strip-shaped groove can be manufactured, and the pattern of the light-transmitting nano pattern template is pressed into a photoresist layer, so that the photoresist enters the groove to form a corresponding long-strip-shaped protrusion; similarly, if the wavy spacer 30 is required to be fabricated, a light-transmitting nano-pattern template with wavy strip-shaped grooves can be fabricated, and the pattern of the light-transmitting nano-pattern template is pressed into the photoresist layer, so that the photoresist enters the grooves to form wavy bulges. In some embodiments, the transparent nano-pattern template may be made of quartz, wherein the quartz is transparent to ultraviolet rays. It can be understood that, in this step, the transparent nano-pattern template needs to be aligned with the substrate 10 and then pressed in, so as to ensure that the formed bumps meet the production requirements.
Step S33b, curing the photoresist layer through ultraviolet irradiation; the photoresist is polymerized and cured by the ultraviolet irradiation, and the longitudinal long-strip-shaped spacer 30 and the wave-shaped spacer 30 are formed correspondingly to the example of the above step.
And step S34b, demolding and etching the residual photoresist layer. The specific manner of demolding can be referred to conventional techniques. It can be understood that the spacers 30 with different shapes have residual photoresists at different positions, for example, the longitudinal strip spacers 30 have residual photoresists in the transverse direction, the transverse strip spacers 30 have residual photoresists in the longitudinal direction, and the etching means is similar to the foregoing means and will not be described herein again.
According to the technical scheme, the black matrix layer 20 is arranged on the substrate base plate 10, the light-transmitting areas 22 for placing the color photoresist 21 are arranged on the black matrix layer 20, the spacers 30 are further arranged on one side, away from the substrate base plate 10, of the black matrix layer 20, the spacers 30 extend along the peripheries of the light-transmitting areas 22, so that the adjacent light-transmitting areas 22 are separated, after the color film base plate 100 and the array base plate 200 are combined into a box and the liquid crystal 300 is injected, each light-transmitting area 22 can enter a certain amount of liquid crystal 300, and as each light-transmitting area 22 is separated, the liquid crystal 300 located in the adjacent light-transmitting areas 22 cannot be influenced by intermolecular acting force, so that the influence of the force of the liquid crystal 300 between pixels is avoided, and the display effect is guaranteed. Thus, the technical scheme of the invention can avoid mutual interference of the liquid crystals 300 corresponding to the adjacent pixels, thereby ensuring the display effect.
Referring to fig. 1, the present invention further provides a display panel 1000, where the display panel 1000 includes an array substrate 200, a color film substrate 100 and a frame sealing adhesive, the color film substrate 100 is disposed opposite to the array substrate 200, the frame sealing adhesive is disposed between the color film substrate 100 and the array substrate 200, when the number of spacers 30 is multiple, the array substrate 200, the color film substrate 100 and the plurality of spacers 30 together enclose a partition space 400 for accommodating a liquid crystal 300, and the color film substrate 100 includes: a base substrate 10; the black matrix layer 20 is arranged on one surface of the substrate base plate 10, and is provided with a plurality of light-transmitting areas 22 for arranging color photoresist 21; the spacer 30 is arranged on one side, away from the substrate base plate 10, of the black matrix layer 20, and the spacer 30 extends along the periphery of the light-transmitting area 22 and separates two adjacent light-transmitting areas 22;
in this embodiment, the frame sealing adhesive is an adhesive, which bonds the upper and lower substrates (the color film substrate 100 and the array substrate 200) of the liquid crystal 300 screen together while maintaining a certain gap, and then seals the filled liquid crystal 300 so that it cannot leak and prevent external contaminants from entering, and is called as frame sealing adhesive. The frame sealing glue for the LCD 300 screen mainly comprises two types: thermal curable adhesives and Ultraviolet (UV) curable adhesives. The two glues differ mainly in their curing pattern. The application of the heat-cured adhesive is wider. However, when the high-precision liquid crystal 300 display screen is manufactured, the UV curing adhesive is superior to the thermal curing adhesive in curing time, adhesion force, humidity resistance, heat resistance and the like. In particular, the curing time is short, the production period is shortened, and the dislocation of two pieces of glass in the long-time curing process is prevented.
It can be understood that, when the spacers 30 are arranged as the transverse long-strip spacers 30, two adjacent transverse long-strip spacers 30 arranged along the longitudinal direction, the array substrate 200 and the color film substrate 100 form a partition space 400, and the corresponding liquid crystal 300 is accommodated in the partition space 400, so that the influence of the liquid crystal 300 in the adjacent partition space 400 is avoided, and the display effect of the display panel 1000 is ensured.
