[0072] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0073] Please refer to the relevant technologies. Figure 1 , Figure 1 This is a schematic diagram of the structure of a liquid crystal display panel provided by related technology. The liquid crystal display panel 00 typically includes: a first substrate 01 and a second substrate 02 disposed opposite to each other, and a liquid crystal layer 03 located between the first substrate 01 and the second substrate 02.

[0074] The first substrate 01 has a first alignment film 013 located on the side of the first substrate 01 near the liquid crystal layer 03. After photoalignment processing is performed on the first alignment film 013, the first alignment film 013 can align the liquid crystal molecules in the liquid crystal layer on the side near the first alignment film 013.

[0075] The second substrate 02 has a second alignment film 023 located on the side of the second substrate 02 near the liquid crystal layer 03. After photoalignment processing is performed on the second alignment film 023, the second alignment film 023 can align the liquid crystal molecules in the liquid crystal layer on the side near the second alignment film 023.

[0076] In this process, after photoalignment treatment of the first alignment film 013 and the second alignment film 023, some liquid crystal molecules in the liquid crystal layer 03 can be orderly arranged according to the alignment directions of the first alignment film 013 and the second alignment film 023, so that all liquid crystal molecules in the liquid crystal layer 03 can be orderly deflected under the action of the electric field. Thus, after the liquid crystal molecules in the liquid crystal display panel 00 are orderly deflected under the action of the electric field, the liquid crystal molecules can be orderly arranged at a certain angle, allowing light to pass through the liquid crystal display panel 00.

[0077] The liquid crystal display panel 00 typically has multiple sub-pixel regions 0a arranged in an array. Specifically, any two adjacent gate lines G and any two adjacent data lines D on the first substrate 01 can form a sub-pixel region 0a.

[0078] Please refer to Figure 2 , Figure 2 This is a top-view illustration of the photoalignment process of a first alignment film provided by related technologies. During the photoalignment process of the first alignment film 013, the portion of the first alignment film 013 in the first substrate 01 within each sub-pixel region 0a can be divided into left and right liquid crystal deflection regions.

[0079] First, after forming a first alignment film 013 in the first substrate 01, a first mask M1 and a second mask M2 are disposed in a direction perpendicular to the first substrate 01. Each of the first mask M1 and the second mask M2 has a light-transmitting area w and a light-blocking area b corresponding to a sub-pixel region 0a, respectively, and the arrangement of the light-transmitting area w and the light-blocking area b in the first mask M1 and the second mask M2 is opposite. Thus, when the first substrate 01 moves uniformly along the Y1 direction, after the portion of the first alignment film 013 in the first substrate 01 within the sub-pixel region 0a is located below the first mask M1, ultraviolet light is irradiated onto the first mask M1, and this ultraviolet light irradiates along the Y2 direction; after the portion of the first alignment film 013 in the first substrate 01 within the sub-pixel region 0a is located below the second mask M2, ultraviolet light is irradiated onto the second mask M2, and this ultraviolet light irradiates along the Y3 direction.

[0080] In this case, please refer to Figure 3 , Figure 3 This is a schematic diagram of the photoalignment of a first alignment film within a sub-pixel region, provided by related technologies. The photoalignment directions of the left and right liquid crystal deflection regions of the first alignment film 013 in the first substrate 01 within the sub-pixel region 0a are opposite.

[0081] Please refer to Figure 4 , Figure 4This is a top-view illustration of the photoalignment process of a second alignment film provided by related technologies. During the photoalignment process of the second alignment film 023, the portion of the second alignment film 023 in each sub-pixel region 0a in the second substrate 02 can be divided into upper and lower liquid crystal deflection regions.

[0082] First, after forming the second alignment film 023 in the second substrate 02, a third mask M3 and a fourth mask M4 are disposed in a direction perpendicular to the second substrate 02. Each of the third mask M3 and the fourth mask M4 has a light-transmitting area w and a light-blocking area b corresponding to a sub-pixel region 0a, and the arrangement of the light-transmitting area w and the light-blocking area b in the third mask M3 and the fourth mask M4 is opposite. Thus, when the second substrate 02 moves uniformly along the X1 direction, after the portion of the second alignment film 023 in the second substrate 02 within the sub-pixel region 0a is located below the third mask M3, ultraviolet light is irradiated onto the third mask M3, and this ultraviolet light irradiates along the X2 direction; after the portion of the second alignment film 023 in the second substrate 02 within the sub-pixel region 0a is located below the fourth mask M4, ultraviolet light is irradiated onto the fourth mask M4, and this ultraviolet light irradiates along the X3 direction.

[0083] In this case, please refer to Figure 5 , Figure 5 This is a schematic diagram of the photoalignment of a second alignment film within a sub-pixel region, provided by related technologies. The photoalignment directions of the upper and lower liquid crystal deflection regions of the second alignment film 023 in the second substrate 02 within the sub-pixel region 0a are opposite.

[0084] Please refer to Figure 6 , Figure 6 This is a schematic diagram of the photoalignment of a liquid crystal display panel provided by related technology. After a first substrate 01 and a second substrate 02 are disposed opposite each other, and liquid crystal is injected between the first substrate 01 and the second substrate 02 to form a liquid crystal layer 03, if an electric field is applied to the liquid crystal display panel 00, the liquid crystal molecules in the liquid crystal layer 03 will deflect in an orderly manner under the action of the electric field. Since the photoalignment directions of the left and right regions of the first alignment film 013 in the first substrate 01 within the sub-pixel region 0a are opposite, and the photoalignment directions of the upper and lower regions of the second alignment film 023 in the second substrate 02 within the sub-pixel region 0a are opposite, there are four liquid crystal deflection regions within the sub-pixel region 0a of the liquid crystal display panel 00, and the deflection directions of the liquid crystal molecules in these four liquid crystal deflection regions are all different.

[0085] However, due to the ordered deflection of liquid crystal molecules under the influence of the electric field, four liquid crystal deflection regions exist within the sub-pixel region 0a, and the deflection directions of the liquid crystal molecules within these four regions are different. Therefore, at the boundary between any two adjacent liquid crystal deflection regions in a sub-pixel region 0a, the arrangement direction of the liquid crystal molecules is uncertain, resulting in a dark line d at the boundary between any two adjacent liquid crystal deflection regions. Light cannot pass through the liquid crystal molecules at this dark line d, and the dark line d is distributed in both the length and width directions of the sub-pixel region 0a. Thus, the presence of dark lines in both the length and width directions of the sub-pixel region 0a leads to low light transmittance of the liquid crystal display panel 00, resulting in poor display performance.

[0086] Please refer to Figure 7 , Figure 7 This is a schematic diagram of the film layer structure of a liquid crystal display surface provided in an embodiment of this application. The liquid crystal display panel 000 may include: a first substrate 100 and a second substrate 200 disposed opposite to each other, and a liquid crystal layer 300 located between the first substrate 100 and the second substrate 200.

[0087] The first substrate 100 has a first alignment film 103 on the side near the liquid crystal layer 300, and the second substrate 200 has a second alignment film 203 on the side near the liquid crystal layer 300.

[0088] The liquid crystal layer 300 contains liquid crystal molecules 301. Specifically, the liquid crystal molecules 301 may have a long axis and a short axis. For example, the liquid crystal molecules 301 may be nematic liquid crystals.

[0089] The liquid crystal display panel 000 can have multiple sub-pixel regions 000a. For a clearer view of the structure of the sub-pixel region 000a, please refer to [reference needed]. Figure 8 , Figure 8 This is a top view of a single sub-pixel region in a liquid crystal display panel provided in an embodiment of this application. Figure 8 The cross-sectional view at point A-A' can be referenced. Figure 7 Each subpixel region 000a in the liquid crystal display panel 000 has 4N subpixel partitions 00a, arranged in a single column, where N is an integer greater than or equal to 1. Thus, at least the 4N subpixel partitions 00a have no overlapping areas. It should be noted that... Figure 8 The illustration uses N equal to 1 as an example, that is, in... Figure 8 The sub-pixel region 000a shown contains four sub-pixel partitions 00a.

[0090] Each sub-pixel partition 00a has a first electrode 102 and a second electrode 202. One of the first electrode 102 and the second electrode 202 is a strip electrode W, and the other is a planar electrode T. The strip electrode W includes multiple electrode strips V, and there is a slit L between two adjacent electrode strips V.

[0091] The first electrode 102 is located on the side of the first alignment film 103 away from the liquid crystal layer 300, and the second electrode 202 is located on the side of the second alignment film 203 away from the liquid crystal layer 300. That is, the first electrode 102 is a part of the first substrate 100, and the second electrode 202 is a part of the second substrate 200.

[0092] When the first electrode 102 is a strip electrode W, it is in contact with the first alignment film 103. Since the first alignment film 103 is located on the side of the first electrode 102 in the first substrate 100 closer to the liquid crystal layer 300, the portion of the first alignment film 103 in contact with the first electrode 102 also forms a slit L corresponding to the strip electrode W. Thus, the long axis of the liquid crystal molecules 301 in contact with the first alignment film 103 is perpendicular to the first alignment film 103, and the liquid crystal molecules 301 in the liquid crystal layer 300 closer to the first alignment film 103 are arranged in an orderly manner along the direction extending from the slit L.

[0093] When the second electrode 202 is a strip electrode W, it is in contact with the second alignment film 203. Since the second alignment film 203 is located on the side of the second substrate 200 where the second electrode 102 is close to the liquid crystal layer 300, the portion of the second alignment film 203 in contact with the second electrode 202 also forms a slit L corresponding to the strip electrode W. Thus, the second alignment film 203 allows the long axis of the liquid crystal molecules 301 in contact with it to be perpendicular to the second alignment film 203, and allows the liquid crystal molecules 301 in the liquid crystal layer 300 near the second alignment film 203 to be arranged in an orderly manner along the direction extending from the slit L.

[0094] Among them, the 4N sub-pixel partitions 00a include 2N first partitions 00a1 and 2N second partitions 00a2. The main extension direction of the electrode strip V in the first partition 00a1 is the first extension direction F1, and the main extension direction of the electrode strip V in the second partition 00a2 is the second extension direction F2. The first extension direction F1 and the second extension direction F2 are different.

[0095] In this embodiment, the main extension direction refers to the fact that most of the electrode strips V in any partition are arranged according to the first extension direction F1, or all of the electrode strips V in any partition are arranged according to the first extension direction F1. Most of the electrode strips V in the first partition 00a1 are arranged according to the first extension direction F1, which means that the liquid crystal molecules 301 located in the slit L are arranged in an orderly manner along the first extension direction F1; most of the electrode strips V in the second partition 00a2 are arranged according to the second extension direction F2, which means that the liquid crystal molecules 301 located in the slit L are arranged in an orderly manner along the second extension direction F2.

[0096] In this application, in each sub-pixel partition 00a, when one of the first electrode 102 and the second electrode 202 is a strip electrode W and the other is a planar electrode T, the alignment film in contact with the planar electrode T needs to undergo photoalignment processing to ensure that the long axis of the liquid crystal molecule 301 in the liquid crystal layer 300 near the planar electrode T has an acute angle with the target plane. That is, the alignment film after photoalignment processing can align the liquid crystal molecule 301. The alignment film in contact with the strip electrode W is not photoaligned, so that the long axis of the liquid crystal molecule 301 closest to the strip electrode W in the liquid crystal layer 300 is perpendicular to the target plane. Here, the target plane is a plane parallel to the liquid crystal display panel 000.

[0097] In one possible scenario, when the first electrode 102 in each sub-pixel region 000a is a strip electrode W and the second electrode 202 in each sub-pixel region 00a is a planar electrode T, only the second alignment film 203 needs to be photoaligned.

[0098] In another possible scenario, when in each sub-pixel region 000a, the first electrode 102 located in N of the 2N first partitions 00a1 is a strip electrode W, and the first electrode 102 located in the other N first partitions 00a1 is a planar electrode T, and the first electrode 102 located in N of the 2N second partitions 00a2 is a strip electrode W, and the first electrode 102 located in the other N second partitions 00a2 is a planar electrode T, then the portion of the first alignment film 103 that contacts the 2N first electrodes 102 that are planar electrodes T needs to be photoaligned, and the portion of the second alignment film 203 that contacts the 2N second electrodes 202 that are planar electrodes T also needs to be photoaligned.

[0099] Please refer to Figure 9 , Figure 9This is a schematic diagram of the light alignment of a liquid crystal display panel provided in an embodiment of this application. In a sub-pixel region 000a, the liquid crystal molecules 301 facing the planar electrode in each sub-pixel partition 00a are aligned. That is, there is an acute angle between the long axis of the liquid crystal molecule 301 closest to the planar electrode in each sub-pixel partition 00a and the target plane.

[0100] In this case, after aligning the liquid crystal molecules 301 through the portion of the first alignment film 103 in contact with the planar electrode T and / or the portion of the second alignment film 203 in contact with the planar electrode T, if the liquid crystal display panel 000... Figure 9 When an electric field is applied to the sub-pixel region 000a shown, the liquid crystal molecules 301 are deflected in an orderly manner under the action of the electric field, so that light can pass through the liquid crystal molecules 301 in the sub-pixel region 000a.

[0101] Furthermore, within a sub-pixel region 000a, the long axis extension directions of the liquid crystal molecules 301 closest to the surface electrode in at least four sub-pixel partitions 00a are all different. For example, when N=1, a sub-pixel region 000a contains four sub-pixel partitions 00a, and the long axis extension directions of the liquid crystal molecules 301 closest to the surface electrode in each of these four sub-pixel partitions 00a are all different. When N is greater than 1, the number of sub-pixel partitions in the 4N sub-pixel partitions 00a where the long axis of the liquid crystal molecules 301 extends in the same direction is the same. In this way, after passing through multiple sub-pixel partitions 00a, the light can exit in different directions, ensuring that the liquid crystal display panel 000 can display images with smaller color differences from all directions, and the fact that the light can exit from all directions of the liquid crystal display panel 000 makes the viewing angle of the liquid crystal display panel 000 wider. Here, the direction of the extension of the long axis of the liquid crystal molecule 301 is the direction in which the long axis of the liquid crystal molecule 301 is located.

[0102] In this embodiment, since the 4N sub-pixel partitions 00a in the sub-pixel region 000a are arranged in a single column, and the 4N sub-pixel partitions 00a are divided into N adjacent groups, each group of pixel partitions 00a contains two first partitions 00a1 and two second partitions 00a2. Therefore, because the liquid crystal molecules 301 in two adjacent sub-pixel partitions 00a are aligned differently, the dark lines generated at the boundary will only be distributed in one direction. For example, as... Figure 9As shown, assuming the sub-pixel region 000a is rectangular in shape, N equals 1, and the two first partitions 00a1 and two second partitions 00a2 are arranged in a single column, the dark lines generated at the junction of two adjacent sub-pixel partitions are only perpendicular to the long side of the sub-pixel region 000a. That is, the dark lines generated at the junction of two adjacent sub-pixel partitions will only be arranged along the short side of the sub-pixel region 000a, not along its long side. Therefore, the light transmittance of the liquid crystal display panel 000 is effectively improved, and the uniformity of the brightness of the light emitted by each sub-pixel region 000a is also ensured, resulting in a better display effect for the liquid crystal display panel 000.

[0103] In summary, this application provides a liquid crystal display panel comprising: a first substrate and a second substrate disposed opposite to each other, and a liquid crystal layer located between the two. The liquid crystal display panel may have multiple sub-pixel regions, each sub-pixel region having 4N sub-pixel partitions arranged in a single column. These 4N sub-pixel partitions are grouped together, or multiple adjacent groups. Each group of pixel partitions includes two first partitions and two second partitions, where N is an integer greater than or equal to 1. Thus, because the liquid crystal molecules in two adjacent sub-pixel partitions have different orientations, the dark lines generated at the boundary will only be distributed in one direction. This effectively improves the light transmittance of the liquid crystal display panel and also ensures good uniformity of brightness of the light emitted from each sub-pixel region, resulting in a better display effect.

[0104] It should be noted that, please refer to Figure 10 , Figure 10 This is a schematic diagram illustrating a partial display on a liquid crystal display panel according to an embodiment of this application. When the liquid crystal display panel 000 is in L255 display mode, all 4N sub-pixel partitions 00a in the sub-pixel region 000a can be observed. Here, L255 display mode refers to the display mode when the sub-pixel region 000a in the liquid crystal display panel 000 reaches its maximum light transmittance. Each sub-pixel region 000a can correspond to displaying a color of light, and the light emitted from the four sub-pixel partitions 00a in each sub-pixel region 00a is the same color. For example, a sub-pixel region 000a displaying red light, a sub-pixel region 000a displaying green light, and a sub-pixel region 000a displaying blue light can be arbitrarily combined to enable the liquid crystal display panel to display richer colors.

[0105] In the embodiments of this application, such as Figure 11 As shown, Figure 11This is a schematic diagram of the film layers of another liquid crystal display panel provided in this application embodiment. In the liquid crystal display panel 000, the first substrate 100 is an array substrate, the first electrode 102 is a pixel electrode, the second substrate 200 is a color filter substrate, and the second electrode 202 is a common electrode.

[0106] For example, the array substrate may include: a first substrate 101, a thin film transistor 104 located on the side of the first substrate 101 near the color filter substrate, a pixel electrode electrically connected to the thin film transistor 104, and a first alignment film 103 located on the side of the pixel electrode away from the first substrate 101.

[0107] The color filter substrate may include: a second substrate 201, a common electrode located on the side of the second substrate 201 close to the array substrate, a color filter layer 204 located on the side of the common electrode away from the second substrate 201, and a second alignment film 203 located on the side of the color filter layer 204 away from the second substrate 201.

[0108] In this application, each thin-film transistor 104 and its electrically connected pixel electrode can be located within a sub-pixel region 000a. The array substrate 100 also integrates multiple data lines D (… Figure 9 (not shown in the image) and multiple grid lines G ( Figure 9 (Not shown in the image) Any two adjacent data lines D and any two adjacent gate lines G can form a sub-pixel region 000a. The gate line G can be electrically connected to the gate of a row of thin-film transistors 104 distributed within the sub-pixel region 000a, the data line D can be electrically connected to the first electrode of a column of thin-film transistors 104 distributed within the sub-pixel region 000a, and the second electrode of the thin-film transistors 104 can be electrically connected to the pixel electrode 202. After applying corresponding electrical signals to the gate line G and data line D, the pixel electrode can be controlled to apply a pixel voltage, so that a voltage difference can be formed between the pixel electrode and the common electrode. Thus, an electric field force capable of driving liquid crystal deflection is formed between the pixel electrode and the common electrode.

[0109] The color filter layer 204 may include color filters located within each sub-pixel region 000a. The color filters distributed in the second substrate 200 may include a red filter, a green filter, and a blue filter. The color filter layer 204 can filter out different colors of light, enabling the liquid crystal display panel to display color images.

[0110] In the embodiments of this application, such as Figure 11As shown, the first electrode 102 and the second electrode 202 in the liquid crystal display panel 000 are both transparent electrodes. This ensures that light can pass through the liquid crystal display panel 000. In each sub-pixel region 000a, the first electrodes 102 within each sub-pixel partition 00a are arranged in the same layer and continuously, and the second electrodes 202 within each sub-pixel partition 00a are arranged in the same layer and continuously. That is, within the same sub-pixel region 000a, each first electrode 102 is formed through a single patterning process, and each first electrode 102 is connected together; within the same sub-pixel region 000a, each second electrode 202 is formed through a single patterning process, and each second electrode 202 is connected together. A single patterning process can refer to: photoresist coating, exposure, development, etching, and photoresist stripping.

[0111] In this case, the first electrode 102 in each sub-pixel partition 00a can generate an electric field force between the first electrode 102 and the second electrode 202 by being driven by the same driving thin film transistor 104.

[0112] In the embodiments of this application, since there are multiple possible implementations for the distribution of the planar electrode T and the strip electrode W in the first electrode 102 and the second electrode 202 in each sub-pixel partition 00a within a sub-pixel region 000a, this application embodiment only illustrates the following two optional implementation methods.

[0113] In the first optional implementation, in each sub-pixel region 000a, the first electrode 102 in each sub-pixel partition 00a is a strip electrode W, and the second electrode 202 in each sub-pixel partition 00a is a planar electrode T; or, the first electrode 102 in each sub-pixel partition 00a is a planar electrode T, and the second electrode 202 in each sub-pixel partition 00a is a strip electrode W. Therefore, the alignment film in contact with the planar electrode T needs to be photoaligned. The liquid crystal molecules 301 in the liquid crystal layer 300 that are close to the planar electrode T can be aligned by this alignment film. That is, there is an acute angle between the long axis of the liquid crystal molecule 301 and the plane where the alignment film is located after photoalignment. The alignment film in contact with the strip electrode W is not photoaligned. The liquid crystal molecules 301 in the liquid crystal layer 300 that are close to the strip electrode W cannot be aligned by this alignment film. Since there is a slit between any two adjacent electrode strips in the strip electrode W, the long axis of the liquid crystal molecule 301 can be perpendicular to the plane where the alignment film is located.

[0114] Taking the photoalignment treatment of the second alignment film 203 as an example, please refer to... Figure 12 , Figure 12This is a schematic diagram of the alignment process of a second alignment film provided in an embodiment of this application. The second alignment film 203 in each sub-pixel partition 00a is aligned, and the alignment directions of the second alignment film 203 in each sub-pixel partition 00a are different.

[0115] For example, during the photoalignment process of the second alignment film 203, the second substrate 200 on which the second alignment film 203 is formed is first uniformly moved along the X direction. When the second substrate 200 moves to a position below the first mask plate P1, and the light-transmitting area w of the first mask plate P1 coincides with a sub-pixel partition 00a in the second alignment film 203, the first mask plate P1 is irradiated with ultraviolet light so that the sub-pixel partition 00a in the second alignment film 203 is irradiated with ultraviolet light, thereby enabling photoalignment of the sub-pixel partition 00a in the second alignment film 203. Subsequently, when the first substrate 100 moves to a position below the third mask P3, and the light-transmitting area w of the third mask P3 coincides with another sub-pixel partition 00a in the second alignment film 203, ultraviolet light is used to irradiate the third mask P3, so that the other sub-pixel partition 00a in the second alignment film 203 is irradiated with ultraviolet light, thereby achieving photo-alignment of this other sub-pixel partition 00a in the second alignment film 203. Then, when the first substrate 100 moves to a position below the second mask P2, and the light-transmitting area w of the second mask P2 coincides with yet another sub-pixel partition 00a in the second alignment film 203, ultraviolet light is used to irradiate the second mask P2, so that yet another sub-pixel partition 00a in the second alignment film 203 is irradiated with ultraviolet light, thereby achieving photo-alignment of yet another sub-pixel partition 00a in the second alignment film 203. Finally, when the first substrate 100 moves to a position below the fourth mask plate P4, and the light-transmitting area w of the fourth mask plate P4 coincides with another sub-pixel partition 00a in the second alignment film 203, the fourth mask plate P4 is irradiated with ultraviolet light so that the other sub-pixel partition 00a in the second alignment film 203 is irradiated with ultraviolet light, thereby enabling photo-alignment of the other sub-pixel partition 00a in the second alignment film 203.

[0116] In this context, the ultraviolet light irradiating the mask is all linearly polarized. After the light emitted from the ultraviolet light source located above the first mask P1 is polarized to obtain the first linearly polarized light, this first linearly polarized light needs to be tilted to irradiate the light-transmitting area w of the first mask P1. Furthermore, the direction of the orthographic projection of the irradiation direction of the first linearly polarized light irradiating the first mask P1 onto the target plane is: Figure 12The arrow is located within the light-transmitting area w of the first mask plate P1, and this arrow direction is parallel to the first extension direction F1. Furthermore, after the first linearly polarized light passes through the light-transmitting area and irradiates the second alignment film 203, the orthogonal projection of the polarization axis of the first linearly polarized light irradiating the second alignment film 203 onto the target plane is parallel to the first extension direction F1.

[0117] After the ultraviolet light emitted from the ultraviolet light source located above the second mask P2 is polarized to obtain second linearly polarized light, this second linearly polarized light needs to obliquely illuminate the light-transmitting area w of the second mask P2. Furthermore, the direction of the projection of the illumination direction of the second linearly polarized light onto the target plane is: Figure 12 The arrow is located within the light-transmitting area w of the second mask plate P2, and this arrow direction is parallel to the second extension direction F2. Furthermore, after the second linearly polarized light passes through the light-transmitting area and irradiates the second alignment film 203, the orthogonal projection of the polarization axis of the second linearly polarized light irradiating the second alignment film 203 onto the target plane is parallel to the second extension direction F2.

[0118] After the ultraviolet light emitted from the ultraviolet light source located above the third mask P3 is polarized to obtain third linearly polarized light, this third linearly polarized light needs to obliquely illuminate the light-transmitting area w of the third mask P3. Furthermore, the direction of the orthographic projection of the illumination direction of the third linearly polarized light onto the target plane is: Figure 12 The arrow is located within the light-transmitting area w of the third mask plate P3, and this arrow direction is parallel to the second extension direction F2. Furthermore, after the third linearly polarized light passes through the light-transmitting area and irradiates the second alignment film 203, the orthogonal projection of the polarization axis of the third linearly polarized light irradiating the second alignment film 203 onto the target plane is parallel to the second extension direction F2.

[0119] After the ultraviolet light emitted from the ultraviolet light source located above the fourth mask P4 is polarized to obtain fourth linearly polarized light, this fourth linearly polarized light needs to obliquely illuminate the light-transmitting area w of the fourth mask P4. Furthermore, the direction of the orthographic projection of the illumination direction of the fourth linearly polarized light onto the target plane is: Figure 12 The arrow is located within the light-transmitting area w of the fourth mask plate P4, and this arrow direction is parallel to the first extension direction F1. Furthermore, after the fourth linearly polarized light passes through the light-transmitting area and irradiates the second alignment film 203, the orthogonal projection of the polarization axis of the fourth linearly polarized light irradiating the second alignment film 203 onto the target plane is parallel to the first extension direction F1.

[0120] It should be noted that when the polarization direction of ultraviolet light is parallel to a straight line, the axis containing that straight line is the polarization axis of the ultraviolet light.

[0121] In this configuration, both the first portion of the second alignment film 203 photo-aligned by the first mask P1 and the fourth portion photo-aligned by the fourth mask P4 can align the liquid crystal molecules 301. Furthermore, the long axes of the liquid crystal molecules 301 in contact with the first portion and the liquid crystal molecules in contact with the fourth portion extend in different tilting directions, but the orthogonal projections of the long axes of the liquid crystal molecules 301 in contact with the first portion and the liquid crystal molecules in contact with the second portion onto the second alignment film 203 are the same as the first extension direction F1.

[0122] The second portion of the second alignment film 203, which is photo-aligned by the second mask P2, and the third portion, which is photo-aligned by the third mask P3, can both align the liquid crystal molecules 301. Furthermore, the long axes of the liquid crystal molecules 301 in contact with the second portion and the liquid crystal molecules in contact with the third portion extend in different tilting directions, but the orthogonal projections of the long axes of the liquid crystal molecules 301 in contact with the third portion and the liquid crystal molecules in contact with the fourth portion onto the second alignment film 203 are both the same as the second extension direction F2.

[0123] In the embodiments of this application, please refer to Figure 13 , Figure 13 This is a schematic diagram of the photoalignment of a second alignment film provided in an embodiment of this application. Figure 13 The arrows located within each pixel partition 00a represent the alignment direction of the second alignment film 203. That is, the liquid crystal molecules 301 in contact with the second alignment film 203 need to be deflected along the arrow direction. The alignment direction of the second alignment film 203 within each sub-pixel partition 00a corresponds to the irradiation direction of ultraviolet light irradiating the first mask P1, the second mask P2, the third mask P3, and the fourth mask P4, respectively. In this way, the light emitted from a sub-pixel region 000a can cover four different directions, enabling the liquid crystal display panel to present images with smaller color differences in four different directions.

[0124] For the second optional implementation method, please refer to... Figure 14 and Figure 15 , Figure 14 This is a schematic diagram of a first electrode provided in an embodiment of this application. Figure 15 This is a schematic diagram of a second electrode provided in an embodiment of this application. Figure 14 and Figure 15All views are top views taken from the second substrate 200 toward the first substrate 100. In each sub-pixel region 000a, the first electrode 102 located in N of the 2N first partitions 00a1 is a strip electrode W, and the first electrode 102 located in the other N first partitions 00a1 is a planar electrode T; the first electrode 102 located in N of the 2N second partitions 00a2 is a strip electrode W, and the first electrode 102 located in the other N second partitions 00a2 is a planar electrode T. In other possible implementations, the first electrode 102 located in each of the 2N first partitions 00a1 is either a strip electrode W or a planar electrode T, and the first electrode 102 located in each of the 2N second partitions 00a2 is either a strip electrode W or a planar electrode T.

[0125] Since there are multiple arrangements of the 4N first electrodes 102 in each sub-pixel region 000a, this application embodiment will only illustrate the following two cases as examples.

[0126] In the first case, within each sub-pixel region 000a, the 4N first electrodes 102 comprise: 2N strip electrodes W and 2N planar electrodes T, with each strip electrode W and each planar electrode T alternating in distribution. For example, when N equals 1, as... Figure 14 As shown, in a sub-pixel region 000a, among the four first electrodes 102, each strip electrode W and each planar electrode T are arranged alternately, as follows: Figure 15 As shown, in a sub-pixel region 000a, the four second electrodes 202 are arranged alternately, with each strip electrode W and each planar electrode T.

[0127] It should be noted that when each strip electrode W and each planar electrode T are arranged alternately, the liquid crystal molecules 301 have a domino effect under the action of the electric field. Therefore, on the same electrode, the liquid crystal molecules 301 located on one side of the planar electrode T can drive the liquid crystal molecules 301 on the adjacent strip electrode W on the same side, so that the liquid crystal molecules 301 can quickly rotate to the designated position, thereby improving the response speed of the liquid crystal display panel.

[0128] In a first partition 00a1 within a sub-pixel region 000a, when the first electrode 102 in one first partition 00a1 is a strip electrode W, the second electrode 202 in that first partition 00a1 is a planar electrode T; when the first electrode 102 in another first partition 00a1 is a planar electrode T, the second electrode 202 in that first partition 00a1 is a strip electrode W. In a second partition 00a2 within a sub-pixel region 000a, when the first electrode 102 in one second partition 00a2 is a strip electrode W, the second electrode 202 in that second partition 00a2 is a planar electrode T; when the first electrode 102 in another second partition 00a2 is a planar electrode T, the second electrode 202 in that second partition 00a2 is a strip electrode W.

[0129] In this case, only the portion of the first alignment film 103 where the first electrode 102 is in contact with the planar electrode T needs to be photoaligned, and only the portion of the second alignment film 203 where the second electrode 202 is in contact with the planar electrode T needs to be photoaligned. Thus, the liquid crystal molecules 301 in the liquid crystal layer 300 near the planar electrode T can be aligned with the portion of the alignment film in contact with the planar electrode T. That is, there is an acute angle between the long axis of the liquid crystal molecule 301 and the plane of the alignment film. However, the long axis of the liquid crystal molecules 301 near the strip electrode W in the liquid crystal layer 300 can be perpendicular to the plane of the alignment film because there is a slit between any two adjacent electrode strips in the strip electrode W.

[0130] In the embodiments of this application, please refer to Figure 16 , Figure 16 yes Figure 14 The diagram shows the alignment process of the first alignment film in contact with the first electrode. The first alignment films 103 in contact with the planar electrode T in the two sub-pixel partitions 00a are all aligned, and the alignment directions of the first alignment films 103 in contact with the planar electrode T in each sub-pixel partition 00a are different.

[0131] For example, during the photoalignment process of the first alignment film 103, which is in contact with the planar electrode T, in each sub-pixel partition 00a, the first substrate 100 on which the first alignment film 103 is formed is first moved uniformly along the X direction. Then, when the first substrate 100 moves to a position below the first mask plate P1, and the light-transmitting area w of the first mask plate P1 coincides with the first alignment film 103 in contact with the planar electrode T in one sub-pixel partition 00a, the first mask plate P1 is irradiated with ultraviolet light. This irradiates the first alignment film 103 in contact with the planar electrode T in one sub-pixel partition 00a, thereby enabling photoalignment of the first alignment film 103 in contact with the planar electrode T in this sub-pixel partition 00a. Finally, when the first substrate 100 moves to a position below the second mask plate P2, and the light-transmitting area w of the second mask plate P2 coincides with the first alignment film 103 in contact with the planar electrode T in another sub-pixel partition 00a, the second mask plate P2 is irradiated with ultraviolet light so that the first alignment film 103 in contact with the planar electrode T in the other sub-pixel partition 00a is irradiated with ultraviolet light, thereby enabling photo-alignment of the first alignment film 103 in contact with the planar electrode T in this sub-pixel partition 00a.

[0132] In this context, the ultraviolet light irradiating the mask is all polarized light. After the light emitted from the ultraviolet light source located above the first mask P1 is polarized to obtain first linearly polarized light, this first linearly polarized light needs to obliquely irradiate the light-transmitting area w of the first mask P1. Furthermore, the direction of the orthographic projection of the irradiation direction of the first linearly polarized light onto the target plane is: Figure 16 The arrow is located within the light-transmitting area w of the first mask plate P1, and this arrow direction is parallel to the first extension direction F1. Furthermore, after the first linearly polarized light passes through the light-transmitting area and irradiates the first alignment film 103, the orthogonal projection of the polarization axis of the first linearly polarized light irradiating the first alignment film 103 onto the target plane is parallel to the first extension direction F1.

[0133] After the ultraviolet light emitted from the ultraviolet light source located above the second mask P2 is polarized to obtain second linearly polarized light, this second linearly polarized light needs to obliquely illuminate the light-transmitting area w of the second mask P2. Furthermore, the direction of the projection of the illumination direction of the second linearly polarized light onto the target plane is: Figure 16 The arrow is located within the light-transmitting area w of the second mask plate P2, and this arrow direction is parallel to the second extension direction F2. Furthermore, after the second linearly polarized light passes through the light-transmitting area and irradiates the first alignment film 103, the orthogonal projection of the polarization axis of the second linearly polarized light irradiating the first alignment film 103 onto the target plane is parallel to the second extension direction F2.

[0134] In this case, please refer to Figure 17 , Figure 17 yes Figure 16 A schematic diagram of the photoalignment of the first alignment film is shown. Figure 17 The arrows located within each pixel partition 00a represent the alignment direction of the first alignment film 103. That is, the liquid crystal molecules 301 in contact with the first alignment film 103 need to be deflected along the arrow direction. The photoalignment direction of the first alignment film 103 in contact with the planar electrode T within one sub-pixel partition 00a is the same as the direction of the ultraviolet light illuminating the first mask P1; the photoalignment direction of the first alignment film 103 in contact with the planar electrode T within the other sub-pixel partition 00a is the same as the direction of the ultraviolet light illuminating the second mask P2.

[0135] In the embodiments of this application, please refer to Figure 18 , Figure 18 yes Figure 15 The diagram shows the alignment process of the second alignment film in contact with the second electrode. The second alignment films 203 in contact with the planar electrode T in the two sub-pixel partitions 00a are all aligned, and the alignment directions of the second alignment films 203 in contact with the planar electrode T in each sub-pixel partition 00a are different.

[0136] For example, during the photoalignment process of the second alignment film 203, which is in contact with the planar electrode T, in each sub-pixel partition 00a, firstly, the second substrate 200 on which the second alignment film 203 is formed is moved uniformly along the X direction. Then, when the second substrate 200 moves to a position below the third mask P3, and the light-transmitting area w of the third mask P3 coincides with the second alignment film 203 in contact with the planar electrode T in one sub-pixel partition 00a, the third mask P3 is irradiated with ultraviolet light. This irradiates the second alignment film 203 in contact with the planar electrode T in one sub-pixel partition 00a, thereby achieving photoalignment of the second alignment film 203 in contact with the planar electrode T in this sub-pixel partition 00a. Finally, when the second substrate 200 moves to a position below the fourth mask plate P4, and the light-transmitting area w of the fourth mask plate P4 coincides with the second alignment film 203 in contact with the planar electrode T in another sub-pixel partition 00a, the fourth mask plate P4 is irradiated with ultraviolet light so that the second alignment film 203 in contact with the planar electrode T in the other sub-pixel partition 00a is irradiated with ultraviolet light, thereby enabling photo-alignment of the second alignment film 203 in contact with the planar electrode T in this sub-pixel partition 00a.

[0137] In this context, the ultraviolet light irradiating the mask is all linearly polarized. After the light emitted from the ultraviolet light source located above the third mask P3 is polarized to obtain third linearly polarized light, this third linearly polarized light needs to be tilted to irradiate the light-transmitting area w of the third mask P3. Furthermore, the direction of the orthographic projection of the irradiation direction of the third linearly polarized light onto the target plane is: Figure 18 The arrow is located within the light-transmitting area w of the third mask plate P3, and this arrow direction is parallel to the second extension direction F2. Furthermore, after the third linearly polarized light passes through the light-transmitting area and irradiates the second alignment film 203, the orthogonal projection of the polarization axis of the third linearly polarized light irradiating the second alignment film 203 onto the target plane is parallel to the second extension direction F2.

[0138] After the ultraviolet light emitted from the ultraviolet light source located above the fourth mask P4 is polarized to obtain fourth linearly polarized light, this fourth linearly polarized light needs to obliquely illuminate the light-transmitting area w of the fourth mask P4. Furthermore, the direction of the orthographic projection of the illumination direction of the fourth linearly polarized light onto the target plane is: Figure 18 The arrow is located within the light-transmitting area w of the fourth mask plate P4, and this arrow direction is parallel to the first extension direction F1. Furthermore, after the fourth linearly polarized light passes through the light-transmitting area and irradiates the second alignment film 203, the orthogonal projection of the polarization axis of the fourth linearly polarized light irradiating the second alignment film 203 onto the target plane is parallel to the first extension direction F1.

[0139] In this case, please refer to Figure 19 , Figure 19 yes Figure 18 A schematic diagram of the photoalignment of the second alignment film is shown. Figure 19 The arrows located within each pixel partition 00a represent the alignment direction of the second alignment film 203. That is, the liquid crystal molecules 301 in contact with the second alignment film 203 need to be deflected along the arrow direction. The photoalignment direction of the second alignment film 203 in contact with the planar electrode T within one sub-pixel partition 00a is the same as the direction of the ultraviolet light illuminating the third mask P3; the photoalignment direction of the second alignment film 203 in contact with the planar electrode T within the other sub-pixel partition 00a is the same as the direction of the ultraviolet light illuminating the fourth mask P4.

[0140] In the second scenario, within each sub-pixel region 000a, the 4N first electrodes 102 comprise: 2N strip electrodes W and 2N planar electrodes T, with two consecutively arranged strip electrodes and two consecutively arranged planar electrodes alternating in arrangement. Please refer to [reference needed].

Figure 21This is a schematic diagram of a second alignment film with a second electrode contact provided in an embodiment of this application. Figure 20 and Figure 21 All are top views taken from the second substrate 200 towards the first substrate 100. For example, when N equals 1, such as... Figure 20 As shown, in a sub-pixel region 000a, among the four first electrodes 102, two consecutively arranged strip electrodes W and two consecutively arranged planar electrodes T are arranged in a single column. Figure 21 As shown, in a sub-pixel region 000a, among the four first electrodes 102, two consecutively arranged strip electrodes W and two consecutively arranged planar electrodes T are also arranged in a single column.

[0141] In this case, only the first alignment film 103, which is in contact with the two consecutively arranged planar electrodes T, needs to undergo photoalignment processing, and only the second alignment film 203, which is in contact with the two consecutively arranged planar electrodes T, needs to undergo photoalignment processing. The process and principle of aligning the first alignment film 103, which is in contact with the two consecutively arranged planar electrodes T, can be referred to the corresponding method in the above embodiments; the process and principle of aligning the second alignment film 203, which is in contact with the two consecutively arranged planar electrodes T, can also be referred to the corresponding method in the above embodiments. Furthermore, the effect of the alignment processing and the arrangement of the liquid crystal molecules 301 can also be referred to the corresponding method in the above embodiments, and this application will not elaborate further on these aspects.

[0142] It should also be noted that when N is greater than or equal to 2, the distribution of the 4N first electrodes 102 within each sub-pixel region 000a can simultaneously include both of the above cases. For example, when N equals 2, the first 4 first electrodes 102 within each sub-pixel region 000a are distributed using the first case described above, and the last 4 first electrodes 102 are distributed using the second case described above.

[0143] In the embodiments of this application, please refer to Figure 22 and Figure 23 , Figure 22 This is a schematic diagram of liquid crystal molecules and planar electrodes in a first partition provided in an embodiment of this application. Figure 23This is a schematic diagram of liquid crystal molecules and planar electrodes in another first partition provided in this application embodiment. After the liquid crystal molecules 301 on the side near the planar electrode T in the liquid crystal layer 300 are aligned by the alignment film, the tilt angle α between their long axis and the target plane is greater than or equal to 87° and less than 90°. Specifically, the principle of photoalignment can be that during the photoalignment process of the alignment film, after being irradiated with ultraviolet light, a polymer is generated on the surface of the alignment film that allows the liquid crystal molecules 301 to arrange themselves in a certain direction. This polymer allows the liquid crystal molecules 301 to arrange themselves along their long axis at a fixed tilt angle α. It should be noted that the long axis direction of the liquid crystal molecules can refer to the direction in which the liquid crystal molecule has a larger length.

[0144] In this embodiment of the application, among the 2N first partitions 00a1, the long axis of the liquid crystal molecules 301 near the surface electrode T in the N first partitions 00a1 extends along the first tilting direction 30a, and the long axis of the liquid crystal molecules 301 near the surface electrode T in the other N first partitions 00a1 extends along the second tilting direction 30b. The first tilting direction 30a and the second tilting direction 30b are different, but the extension directions of the orthogonal projections of the first tilting direction 30a and the second tilting direction 30a on the target plane are both parallel to the first extension direction F1.

[0145] In this case, taking the first partition 00a1, where the liquid crystal molecules 301 extending along the first tilt direction 30a are located, as an example, when the liquid crystal display panel 000 applies an electric field to the first partition 00a1, the liquid crystal molecules 301 closest to the planar electrode T in the liquid crystal layer 300 will be deflected in an orderly manner from the first tilt direction 30a toward the target plane under the action of the electric field, thereby allowing light to pass through the liquid crystal molecules 301 in the sub-pixel region 000a. Furthermore, since the long axis of the liquid crystal molecules 301 closest to the strip electrode W in the liquid crystal layer 300 is perpendicular to the target plane, and the extension direction of the slit in the strip electrode W is the same as the orthogonal projection direction of the first tilt direction 30a onto the target plane, under the action of the electric field, the deflection direction of the liquid crystal molecules 301 closest to the strip electrode W in the liquid crystal layer 300 is the same as the deflection direction of the liquid crystal molecules 301 closest to the planar electrode T in the liquid crystal layer 300. In this way, all the liquid crystal molecules 301 in the first partition 00a1 deflect in the same direction, and the response speed of the liquid crystal display panel 000 is faster.

[0146] In this embodiment, among the 2N second partitions 00a2, the long axis of the liquid crystal molecules 301 near the planar electrode T in the N second partitions 00a2 extends along a third inclined direction, and the long axis of the liquid crystal molecules 301 near the planar electrode T in the other N second partitions 00a2 extends along a fourth inclined direction. The third and fourth inclined directions are different, but the extension directions of the orthogonal projections of the third and fourth inclined directions on the target plane are both parallel to the second extension direction F2. The principle and structure of the third and fourth inclined directions are explained in the above description of the structure and principle of the liquid crystal molecules 301 in the 2N first partitions 00a1, and will not be repeated here.

[0147] In this application, since the 4N sub-pixel partitions 00a are grouped together, or N adjacent groups, each group of pixel partitions 00a contains two first partitions 00a1 and two second partitions 00a2. N can be an integer greater than or equal to 1. Therefore, the structure of each sub-pixel partition 00a in the multiple arrayed sub-pixel regions 000a is the same, ensuring a good display effect for the liquid crystal display panel 000.

[0148] For example, for ease of description below, point Q is defined as the origin. With point Q as the origin, the 0-degree horizontal direction to the right is defined as the positive direction of the X-axis, and the direction rotating 90 degrees clockwise is defined as the positive direction of the Y-axis. The tilting extension direction of the liquid crystal molecules 301 in each of the first partitions 00a1 and each of the second partitions 00a2 in the liquid crystal display panel 000 will be explained. Since there are multiple arrangements of the partitions within the same group of pixel partitions 00a, this embodiment will only illustrate the following two cases.

[0149] For the first scenario, please refer to... Figure 24 and Figure 25 , Figure 24 This is a schematic diagram of another first alignment film with a first electrode contact provided in an embodiment of this application. Figure 25 This is a schematic diagram of a second alignment film with another second electrode contact configuration provided in an embodiment of this application. Figure 24 and Figure 25All views are top views viewed from the second substrate 200 towards the first substrate 100. Within the same set of pixel partitions 00a, each first partition 00a1 and each second partition 00a2 are arranged alternately. The first electrode 102 in each first partition 00a1 is a planar electrode, and the second electrode 202 in each first partition 00a1 is a strip electrode; the first electrode 102 in each second partition 00a2 is a strip electrode, and the second electrode 202 in each second partition 00a2 is a planar electrode. In this case, the extension direction of the long axis of the liquid crystal molecules 301 on the side of the first alignment film 103 in contact with the planar electrode T in the two first partitions 00a1 is parallel to the first extension direction F1 when projected onto the target plane; the extension direction of the long axis of the liquid crystal molecules 301 on the side of the second alignment film 203 in contact with the planar electrode T in the two second partitions 00a2 is parallel to the second extension direction F2 when projected onto the target plane.

[0150] For example, in the same group of pixel partitions 00a, the long axes of liquid crystal molecules 301 arranged sequentially along a 90-degree direction in two first partitions 00a1 have angles of 45° and 225° respectively when projected onto the target plane, and the angle between the projected extension directions of the long axes of the liquid crystal molecules 301 in the two first partitions 00a1 are 180°. Similarly, in the same group of pixel partitions 00a, the long axes of liquid crystal molecules 301 arranged sequentially along a 90-degree direction in two second partitions 00a2 have angles of 315° and 135° respectively when projected onto the target plane, and the angle between the projected extension directions of the long axes of the liquid crystal molecules 301 in the two second partitions 00a2 are 180°.

[0151] In the second scenario, within the same pixel partition 00a, two second partitions 00a2 are arranged between two first partitions 00a1. The first electrode 102 in one of the two first partitions 00a1 is a strip electrode W, and the electrode in the other first partition 00a1 is a planar electrode T. Similarly, the first electrode 102 in one of the two second partitions 00a2 is a strip electrode W, and the electrode in the other second partition 00a2 is a planar electrode T.

[0152] In this case, there are multiple combinations of photoorientation directions in the planar electrodes T in each first partition 00a1 and each second partition 00a2. The embodiments of this application will be illustrated with the following two possible combinations.

[0153] In this application, the long axis of the liquid crystal molecule 301 on the alignment film side that is in contact with the planar electrode T in each first partition 00a1 extends in a direction parallel to the first extension direction F1 when projected onto the target plane; the long axis of the liquid crystal molecule 301 on the alignment film side that is in contact with the planar electrode T in each second partition 00a2 extends in a direction parallel to the second extension direction F2 when projected onto the target plane.

[0154] The first possible combination is as follows: Figure 20 As shown, the long axis of the liquid crystal molecule 301 on one side of the first alignment film 103 in contact with the planar electrode T within a first partition 00a1 forms an angle of 45° with the 0° direction when projected onto the target plane; the long axis of the liquid crystal molecule 301 on one side of the first alignment film 103 in contact with the planar electrode T within a second partition 00a2 forms an angle of 315° with the 0° direction when projected onto the target plane. Figure 21 As shown, the long axis of the liquid crystal molecule 301 on the side of the second alignment film 203 in contact with the planar electrode T in another first partition 00a1 has an angle of 225° between the extension direction of its orthogonal projection on the target plane and the 0° direction; the long axis of the liquid crystal molecule 301 on the side of the second alignment film 203 in contact with the planar electrode T in another second partition 00a2 has an angle of 135° between the extension direction of its orthogonal projection on the target plane and the 0° direction.

[0155] The second possible combination is as follows: Figure 17 As shown, the long axis of the liquid crystal molecule 301 on one side of the first alignment film 103 in contact with the planar electrode T within a first partition 00a1 forms an angle of 45° with the 0° direction when projected onto the target plane; the long axis of the liquid crystal molecule 301 on one side of the first alignment film 103 in contact with the planar electrode T within a second partition 00a2 forms an angle of 135° with the 0° direction when projected onto the target plane. Figure 19 As shown, the long axis of the liquid crystal molecule 301 on the side of the second alignment film 203 in contact with the planar electrode T in another first partition 00a1 has an angle of 225° between the extension direction of its orthogonal projection on the target plane and the 0° direction; the long axis of the liquid crystal molecule 301 on the side of the second alignment film 203 in contact with the planar electrode T in another second partition 00a2 has an angle of 315° between the extension direction of its orthogonal projection on the target plane and the 0° direction.

[0156] It should be noted that the first extension direction F1 and the second extension direction F2 are perpendicular. Thus, the major axis of the liquid crystal molecule 301 always forms a 45-degree angle with the 90° direction in the same pixel partition 00a. This allows light to pass through the sub-pixel region 000a under the influence of the electric field, taking into account all four mutually perpendicular directions, resulting in less color difference in the image displayed by the liquid crystal display panel in these four directions. Furthermore, the domino effect produced by the liquid crystal molecules 301 under the influence of the electric field is more pronounced, further improving the response speed of the liquid crystal display panel.

[0157] Of the two optional implementation methods mentioned above, the liquid crystal display panel provided in this application only requires the panel to move in the X direction during the alignment process to achieve photoalignment of the alignment film within the sub-pixel region 000a. This eliminates the need for the panel to move in two directions, effectively simplifying the manufacturing process of the liquid crystal display panel.

[0158] Please refer to Figure 26 , Figure 26 This is a simulation result diagram of the transmittance of a liquid crystal display panel provided in an embodiment of this application. Curve A1 represents the transmittance curve of a single sub-pixel region 0a in a liquid crystal display panel in the related art, where the single sub-pixel region 0a is the one described above. Figure 6 The sub-pixel region 0a is shown. Curve A2 represents the transmittance curve of a single sub-pixel region 000a in the liquid crystal display panel of this application, where the single sub-pixel region 000a is as described above. Figure 17 and the above Figure 19 The sub-pixel region 000a behind the cell is an example of a liquid crystal display panel. Unlike related technologies where dark lines exist in both the length and width directions of a single sub-pixel region 0a, in this application, dark lines only exist in the width direction of a single sub-pixel region 000a. Therefore, the light transmittance of the liquid crystal display panel represented by A2 is greater than that of the liquid crystal display panel represented by A1. For example, within a voltage range of 5V to 9V, the transmittance of A2 is significantly greater than that of A1.

[0159] In summary, this application provides a liquid crystal display panel comprising: a first substrate and a second substrate disposed opposite to each other, and a liquid crystal layer located between the two. The liquid crystal display panel may have multiple sub-pixel regions, each sub-pixel region having 4N sub-pixel partitions arranged in a single column. These 4N sub-pixel partitions are grouped together, or multiple adjacent groups. Each group of pixel partitions includes two first partitions and two second partitions, where N is an integer greater than or equal to 1. Thus, because the liquid crystal molecules in two adjacent sub-pixel partitions have different orientations, the dark lines generated at the boundary will only be distributed in one direction. This effectively improves the light transmittance of the liquid crystal display panel and also ensures good uniformity of brightness of the light emitted from each sub-pixel region, resulting in a better display effect.

[0160] This application embodiment also provides a method for manufacturing a liquid crystal display panel, which may include:

[0161] Step S1: Form a first substrate having a first electrode and a first alignment film.

[0162] Step S2: Form a second substrate having a second electrode and a second alignment film.

[0163] Step S3: The first substrate and the second substrate are assembled together, and a liquid crystal layer is formed between the first substrate and the second substrate.

[0164] The liquid crystal display panel has multiple sub-pixel areas, each sub-pixel area having 2N first partitions and 2N second partitions, arranged in a single column, where N is an integer greater than or equal to 1.

[0165] Furthermore, each sub-pixel partition has a first electrode and a second electrode; one of the first electrode and the second electrode is a strip electrode and the other is a planar electrode; the strip electrode includes multiple electrode strips, and there is a slit between two adjacent electrode strips.

[0166] When the first electrode is a strip electrode, the first electrode is in contact with the first alignment film; when the second electrode is a strip electrode, the second electrode is in contact with the second alignment film.

[0167] Among them, the 4N sub-pixel partitions include 2N first partitions and 2N second partitions. The main extension direction of the electrode strips in the first partition is the first extension direction, and the main extension direction of the electrode strips in the second partition is the second extension direction. The first extension direction and the second extension direction are different.

[0168] It should be noted that, during the formation of the first substrate having a first electrode and a first alignment film, a first alignment film can be formed on the first electrode of the first substrate by any of a variety of methods such as deposition, coating, and sputtering. During the formation of the second substrate having a second electrode and a second alignment film, a second alignment film can be formed on the common electrode of the second substrate by any of a variety of methods such as deposition, coating, and sputtering. The materials used to form the first and second alignment films can be polyimide or other materials with alignment functions; this application does not limit their use.

[0169] It should also be noted that, since one of the first and second electrodes is a strip electrode and the other is a planar electrode, and the strip electrode comprises multiple electrode strips with a slit between two adjacent electrode strips, one of the first and second electrodes has a slit, which is formed by an etching process.

[0170] In this embodiment of the application, after forming a first substrate having a first electrode and a first alignment film, the method for manufacturing a liquid crystal display panel further includes:

[0171] The portion of the first alignment film that is in contact with the planar electrode is photoaligned so that the portion of the first alignment film that is in contact with the planar electrode can align the liquid crystal molecules in the liquid crystal layer.

[0172] After forming a second substrate having a second electrode and a second alignment film, the method for manufacturing a liquid crystal display panel further includes:

[0173] The portion of the second alignment film that contacts the planar electrode is photoaligned so that the portion of the second alignment film that contacts the planar electrode can align the liquid crystal molecules in the liquid crystal layer.

[0174] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific principles of the liquid crystal display panel described above can be referred to the corresponding content in the embodiments of the aforementioned liquid crystal display panel structure, and will not be repeated here.

[0175] This application also provides a display device, which can be any device with display function, such as a smartphone, smart computer, television, navigator, or smart wearable device. Please refer to... Figure 27 , Figure 27 This is a schematic diagram of the film layer structure of a display device provided in an embodiment of this application. The display device 111 may include: a backlight 010 and the above-described... Figure 7 or and Figure 11 The liquid crystal display panel 000 is shown.

[0176] The backlight 010 is located on the back of the liquid crystal display panel 000, and the light emitted by the backlight 010 can be directed toward the liquid crystal display panel. For example, when the liquid crystal molecules in the liquid crystal display panel 000 are deflected in an orderly manner under the action of an electric field, the light emitted by the backlight 010 can pass through the liquid crystal display panel 000, thus enabling the liquid crystal display panel 000 to display an image.

[0177] It should be noted that the dimensions of layers and regions may be exaggerated in the accompanying drawings for clarity. Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers. Additionally, it is understood that when an element or layer is referred to as being "below" another element or layer, it can be directly below the other element, or there may be more than one intermediate layer or element. Furthermore, it is also understood that when a layer or element is referred to as being "between" two layers or two elements, it can be the only layer between the two layers or two elements, or there may be more than one intermediate layer or element. Similar reference numerals throughout indicate similar elements.

[0178] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0179] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
