the first base plate comprises a first substrate base plate, the second base plate comprises a second substrate base plate, and the plurality of barrier parts are positioned between the first substrate base plate and the second substrate base plate;
the blocking part is only positioned on one side of the end part of the spacer 103 in the set direction;
the set direction is the direction of the sliding tendency of the end of the spacer 103 after the curved display panel is bent;
the blocking part is used for blocking the shock insulator from sliding along the set direction.
In the curved-surface display panel provided by the embodiment of the invention, the plurality of blocking parts are arranged between the first substrate and the second substrate, the blocking parts are only arranged on one side of the end part of the spacer in the set direction, and the spacer is blocked by the blocking parts from sliding along the set direction, so that light leakage of the curved-surface display panel caused by sliding of the spacer under the action of stress is avoided, the dark-state light leakage phenomenon of the curved-surface display panel is improved, and the performance and the yield of the curved-surface display panel are improved.
In the embodiment of the present invention, in order to clearly illustrate the specific structures of the spacers and the barrier portions, the liquid crystal layer is omitted in each drawing, and in the specific implementation, the liquid crystal layer should be further disposed between the first substrate and the second substrate. In specific implementation, the first substrate is a color film substrate, and the second substrate is an array substrate; alternatively, the first substrate is an array substrate, the second substrate is a color filter substrate, and the description is not limited herein.
In specific implementation, in order to avoid the spacer affecting the aperture ratio of the curved display panel and further affecting the display effect of the curved display panel, the spacer is generally disposed in a non-opening region of the pixel unit, that is, the spacer may be disposed in a range covered by the black matrix. Specifically, the spacers are generally disposed in the gaps between adjacent pixel units, and generally, a plurality of spacers are uniformly distributed, and the specific distribution of the spacers can be determined according to the contact density of the spacers which is actually required.
In an actual process, spacers are generally formed on a surface of the first substrate, and after the first substrate and the second substrate are aligned, the spacers can be supported between the first substrate and the second substrate. The first substrate and the second substrate after the cassette are bent by stress, and the end of the spacer is likely to slide in a set direction or tends to slide in the set direction under the stress. In the embodiment of the invention, the blocking part is arranged on one side of the end part of the spacer in the set direction, so that the end part of the spacer can be effectively blocked from sliding along the set direction, in addition, in order to avoid influencing the aperture opening ratio of the curved display panel, the blocking part is required to be arranged in the area between the spacer and the opening area of the pixel unit, namely, the blocking part is arranged in the non-opening area of the pixel unit, and the blocking part is only arranged on one side of the spacer in the set direction, so that the space occupied by the blocking part can be saved.
Specifically, the following describes in detail the manner of disposing the blocking portion in the embodiment of the present invention with reference to the drawings.
The setting mode is as follows:
as shown in fig. 2 and 3, the blocking portion includes: a first barrier 300 on a side of the second substrate facing the first substrate 100;
the setting direction is the sliding tendency of one end of the spacer 103 close to the second substrate 200 after the curved display panel is bent.
The spacer 103 is generally formed on the surface of the first substrate 100, after the first substrate 100 and the second substrate 200 are aligned to each other, the end of the spacer 103 contacts with the second substrate 200, when the first substrate 100 and the second substrate 200 are bent after aligning to each other, the end of the spacer 103 close to the second substrate 200 is more likely to slide, once the spacer 103 slides, the alignment film on the surface of the second substrate 200 is easily scratched under the action of extrusion and friction, which causes light leakage of the curved display panel, and the amount of deformation of the spacer 103 at the edge of the curved display panel is greater, which makes the curved display panel more likely to have four corners light leakage. Therefore, in the first arrangement mode, the first blocking portion 300 is disposed on the side of the second substrate 200 facing the first substrate 100, so that the sliding of the spacer 103 near the second substrate 200 can be effectively prevented, and the four-sided light leakage phenomenon of the curved display panel can be avoided.
As shown in fig. 1, the curved display panel includes: two curved first edges L1, two second edges L2 extending in a straight direction, and a center line L3 located between the two second edges L2.
Specifically, in the curved display panel provided by the embodiment of the present invention, as shown in fig. 2, the bending axis T of the curved display panel is located on a side of the first substrate 100 away from the second substrate 200;
the first barrier 300 is located on the side of the spacer 103 facing away from the center line L3.
In the embodiment of the present invention, the bending axis T may be an axis when the first substrate 100 and the second substrate 200 after the box are bent, that is, the first substrate 100 and the second substrate 200 after the box are bent with the bending axis T as an axis in an actual process, and the cross section of the curved display panel shown in fig. 2 is taken as an example, and the bending axis extending in a direction perpendicular to the plane of the drawing is represented by a circular black dot T in the drawing.
As shown in fig. 2, the bending axis T is located on a side of the first substrate 100 away from the second substrate 200, and the first substrate 100 and the second substrate 200 protrude toward the direction in which the first substrate 100 points toward the second substrate 200. After the first substrate 100 and the second substrate 200 are bent, the end of the spacer 103 close to the second substrate 200 will have a tendency to slide towards the edge of the curved display panel, as shown in fig. 2, in the region to the left of the center line L3, each spacer 103 has a tendency to slide in the direction of the arrow S1 at the end close to the second substrate 200, in the area to the right of the center line L3, each spacer 103 has a tendency to slide in the direction of the arrow S2 at the end close to the second substrate 200, the first blocking portion 300 may be disposed at a side of the spacer 103 facing away from the center line L3 to effectively block the sliding of the spacer 103, specifically, in the region on the left side of the center line L3, each first stopper 300 is disposed on one side of the corresponding spacer 103 in the S1 direction, in the region on the right side of the center line L3, each first stopper 300 is disposed on one side of the corresponding spacer 103 in the S2 direction.
Specifically, in the curved display panel provided by the embodiment of the present invention, as shown in fig. 3, the bending axis T of the curved display panel is located on a side of the second substrate 200 away from the first substrate 100;
the first barrier 300 is located on the side of the spacer 103 near the center line L3.
Referring to fig. 3, the bending axis T is located on a side of the second substrate 200 away from the first substrate 100, and the first substrate 100 and the second substrate 200 protrude toward the second substrate 200 in a direction toward the first substrate 100. After the first substrate 100 and the second substrate 200 are bent, the end of the spacer 103 close to the second substrate 200 will have a tendency to slide toward the center of the curved display panel, as shown in fig. 3, in the region to the left of the center line L3, each spacer 103 has a tendency to slide in the direction of the arrow S3 at the end close to the second substrate 200, in the area to the right of the center line L3, each spacer 103 has a tendency to slide in the direction of the arrow S4 at the end close to the second substrate 200, the first blocking portion 300 may be provided at a side of the spacer 103 close to the center line L3 to effectively block the sliding of the spacer 103, specifically, in the region on the left side of the center line L3, each first stopper 300 is disposed on one side of the corresponding spacer 103 in the S3 direction, in the region on the right side of the center line L3, each first stopper 300 is disposed on one side of the corresponding spacer 103 in the S4 direction.
In an alternative embodiment, as shown in fig. 2 and 3, the first blocking portion 300 may be disposed at a position close to the corresponding spacer 103 when the space allows, so as to ensure that the first blocking portion 300 can effectively block the corresponding spacer 103 from sliding, and in a specific implementation, on the basis of ensuring that the first blocking portion 300 can effectively block the corresponding spacer 103 from sliding, the first blocking portion 300 may also have a certain distance from the corresponding spacer 103, where the specific position of the first blocking portion 300 is not limited.
Further, in the curved display panel according to the embodiment of the present invention, the rule of change of the size of each first barrier 300 is described by taking each first barrier shown in fig. 4 as an example, specifically, fig. 4 is a schematic view of each first barrier 300 in a right region of a center line L3 of the cross section shown in fig. 2, and each first barrier 300 shown in fig. 4 is located in the same cross section cut by a dotted line M in fig. 1.
It should be noted that, the first blocking portions in the left area of the center line L3 in fig. 2, the first blocking portions in the left area of the center line L3 in fig. 3, and the first blocking portions in the right area of the center line L3 in fig. 3 also have a similar rule with the size of the first blocking portions shown in fig. 4, and are not described in detail here.
In any cross section perpendicular to the curved display panel and parallel to the first edge L, the height of the first barrier 300 in the direction perpendicular to the second substrate 200 gradually increases in a direction (a direction indicated by an arrow S2 in fig. 4) in which the center line L3 points to the second edge L2, and in fig. 4, the height of each first barrier 300 is h1, h2 … … hn in the direction of an arrow S2, and h1 < h2 < … … < hn;
and/or the presence of a gas in the gas,
in any cross section perpendicular to the curved display panel and parallel to the first edge L1, the width of the first barrier 300 in the direction in which the center line L3 points to the second edge L2 (the direction indicated by the arrow S2 in fig. 4) gradually increases in the direction in which the center line L3 points to the second edge L2, and in fig. 4, the width of each first barrier 300 in the direction of the arrow S2 is d1 and d2 … … dn, respectively, and d1 < d2 < … … < dn.
In a specific implementation, the height of the first barrier 300 may be set to be not more than two thirds of the height of the spacer 103, specifically, the height of the spacer 103 is about 3 μm, the height of the first barrier 300 may be set to be in a range of 0.5 μm to 2 μm, or the height of each first barrier 300 may be set according to practical situations, and the height value of the first barrier is not limited herein.
In practical applications, in order to avoid affecting the aperture ratio of the pixel unit, the spacer 103 and the first barrier 300 may be disposed in a non-open area of the pixel unit, and the spacer 103 may be disposed in a non-open area between adjacent pixel units, and thus, the first barrier 300 may be disposed in an area between the spacer 103 and the open area of the pixel unit, specifically, the spacer 103 has a width of about 9 μm, the spacer 103 has a distance of about 10 μm between the edge of the spacer 103 and the open area, and the first barrier 300 may have a width in a range of 5 μm to 10 μm to ensure that the first barrier 300 is located in the non-open area.
Referring also to fig. 4, in the direction of the arrow S2, the deformation amount of the spacers 103 at different positions is different, and specifically, in the direction in which the center line L3 points to the second edge L2, the deformation amount of the spacers 103 is greater, and therefore, the spacers 103 closer to the second edge L2 are more likely to slide, and therefore, in the direction in which the center line L3 points to the second edge L2, the size of each first blocking portion 300 is gradually increased, and the corresponding spacers 103 can be blocked more effectively from sliding, so that the dark-state light leakage phenomenon of the curved display panel can be avoided.
In addition, in any cross section perpendicular to the curved display panel and parallel to the second edge L2, the deformation amount of each spacer 103 is substantially the same, and thus, the height of each first barrier 300 may be set to be the same, and the width of each first barrier 300 may also be set to be the same.
In a specific implementation, as shown in fig. 5, in the curved display panel provided in the embodiment of the present invention, fig. 5 is a schematic structural diagram of the curved display panel before being bent, and the second substrate 200 may further include: a common electrode layer 202 positioned on one side of the second substrate base plate 201 close to the first substrate 100, and a first planarization layer 203 positioned on one side of the common electrode layer 202 close to the second substrate base plate 201;
the first planarization layer 203 has a plurality of first protrusions W1, which are illustrated as one first protrusion W1 without limiting the number of first protrusions W1, on a side close to the first substrate 100;
the first stopper 300 includes a first protrusion W1.
By arranging the plurality of first protrusions W1 on the side of the first planarization layer 203 close to the first substrate 100 and the first barrier 300 including the first protrusions W1, the first barrier 300 has better stability due to the fact that the first protrusions W1 are on a certain film layer above the second substrate 201, and the first barrier 300 is guaranteed to block the corresponding spacer 103 from sliding.
In an actual process, the first planarization layer 203 is formed on each film layer of the thin film transistor TFT to planarize each film layer of the thin film transistor TFT, a plurality of first protrusions W1 are formed on a side of the first planarization layer 203, which is away from the second substrate 201, and then other film layers formed on a side of the first planarization layer 203, which is away from the second substrate 201, may also form protrusions along with the profile of the first protrusions W1, so that the first barrier 300 may further include protrusions formed by other film layers.

It should be noted that after the first alignment layer 104 is formed on the side of each spacer 103 in the first substrate 100 facing away from the first substrate 101, a certain amount of the material of the first alignment layer 104 remains on the end surface of the spacer 103 facing away from the first substrate 101, and then after the rubbing alignment process is performed on the first alignment layer 104, the material of the first alignment layer 104 remaining on the end surface of the spacer 103 facing away from the first substrate 101 is rubbed off.
In an alternative embodiment, the curved display panel includes a display region and a non-display region surrounding the display region, the first alignment layer 104 is disposed in the entire display region except for the spacers 103, and the second alignment layer 208 is disposed in the entire display region.

In an alternative embodiment, the second insulating layer 204 may be omitted, that is, the curved display panel may include a first insulating layer 205 located between the first flat layer 203 and the common electrode layer 202, a pixel electrode 207 located on a side of the first insulating layer 205 away from the second substrate 201, a third insulating layer 206 located between the pixel electrode 207 and the common electrode layer 202, and a second alignment layer 208 located on a side of the pixel electrode 207 close to the first substrate 100. In this embodiment, the first barrier 300 may include a first protrusion W1, and protrusions formed by the first insulating layer 205, the common electrode layer 202, the third insulating layer 206, and the second alignment layer 208.
In practical applications, the number of film layers in the first barrier 300 may be determined according to the height of the first barrier 300 to be formed, and in particular, the thickness of the first barrier 300 may be adjusted by adjusting the number of insulating layers formed over the first protrusion W1.
In specific implementation, the thickness of the first blocking portion 300 at different positions may be adjusted by using a halftone mask, or the thickness of the first blocking portion 300 may also be adjusted by adjusting the number of film layers included in the first blocking portion 300 at different positions, which is not limited herein.
In addition, in the curved display panel according to an embodiment of the present invention, as shown in fig. 6, fig. 5 is a schematic structural view of the curved display panel before being bent, and the second substrate may further include: a touch electrode layer (e.g., a film layer shown as 202) on a side of the second substrate 201 close to the first substrate 100, a touch wiring layer (e.g., a film layer shown as W2) on a side of the touch electrode layer close to the second substrate 201, and a second insulating layer 204 between the touch electrode layer and the touch wiring layer;
the touch routing layer has a plurality of second protrusions W2 suspended in the air on a side close to the first substrate 100, which is schematically illustrated by a second protrusion W2, and the number of the second protrusions W2 is not limited;
the first blocking part 300 includes a second protrusion.
It should be noted that, each second bump in the touch routing layer is configured to be floating, which means that the second bump is not connected to any signal line, and no signal is applied to the second bump W2.
Through set up a plurality of second archs at one side that the touch-control routing layer is close to first base plate, and first barrier part includes that the second is protruding, because the second is protruding to be formed at certain rete on the second substrate base plate, therefore can make first barrier part have better stability, guarantees that first barrier part can block that corresponding shock insulator takes place to slide.
In addition, the touch electrode layer may be reused as a common electrode layer, or may be a touch electrode layer separately disposed, which is not limited herein.
In an actual process, a plurality of second protrusions are formed on a side of the touch routing layer close to the first substrate, and then other film layers formed on a side of the touch routing layer close to the first substrate may also form protrusions along with the contours of the second protrusions, so that the first barrier portion may further include protrusions formed by other film layers, for example, in fig. 6, the first barrier portion 300 may further include protrusions formed by film layers such as the second insulating layer 204, the first insulating layer 205, the touch electrode layer, the third insulating layer 206, and the second alignment layer 208. In an alternative embodiment, the second insulating layer 204 may be omitted, that is, the first barrier portion 300 may also include a second protrusion, and the protrusions formed by the first insulating layer 205, the touch electrode layer, the third insulating layer 206, the second alignment layer 208, and the like.
In practical applications, the number of the film layers in the first barrier may be determined according to the height of the first barrier to be formed. Specifically, the height of the first barrier 300 may be adjusted by adjusting the number of insulating layers formed over the second protrusion W2.
In specific implementation, the thickness of the first blocking portion at different positions may be adjusted by using a halftone mask, or the thickness of the first blocking portion may also be adjusted by adjusting the number of film layers included in the first blocking portion at different positions, which is not limited herein.
Furthermore, as shown in fig. 7, in order to increase the thickness of the first barrier 300, it is also possible to adopt a manner in which the first protrusion W1 overlaps the second protrusion W2, that is, at the position of the same first barrier 300, the orthographic projections of the first protrusion W1 and the second protrusion W2 on the second substrate base 201 have an overlapping region.
In an optional implementation manner, the first substrate of the curved display panel further includes a black matrix and a color resist layer, where the black matrix includes: the color filter comprises a plurality of first black matrix strips extending along the row direction and a plurality of second black matrix strips extending along the column direction, wherein the first black matrix strips and the second black matrix strips form a grid shape, and the first black matrix strips and the second black matrix strips divide the color resistance layer into a plurality of display sub-pixels arranged in an array. Since the first black matrix strip extending in the row direction needs to shield components such as thin film transistors, and the second black matrix strip extending in the column direction needs to shield some signal lines, the first black matrix strip is generally wider than the second black matrix strip, and therefore, the first protrusion or the second protrusion can be arranged at a position between two adjacent rows of sub-pixels, namely, at a position shielded by the first black matrix strip, and the orthographic projection of the first protrusion or the second protrusion on the second substrate is located in the range of the orthographic projection of the black matrix on the second substrate, and therefore, the first protrusion or the second protrusion does not affect the display effect of the display panel.
The setting mode is two:
as shown in fig. 8 and 9, the blocking portion includes: a second barrier 400 on a side of the first substrate base facing the second substrate 200;
the setting direction is the direction of the sliding tendency of one end of the spacer 103 close to the first substrate 100 after the curved display panel is bent.
In practical applications, when the boxed first substrate 100 and the second substrate 200 are bent, the end of the spacer 103 close to the second substrate 200 is easy to slide, and the end of the spacer 103 close to the first substrate 100 has a sliding tendency in the opposite direction, so that the plurality of second blocking portions 400 at the side of the first substrate 100 facing the second substrate 200 can effectively prevent the sliding of the spacer 103 close to the first substrate 100, and avoid the dark-state light leakage phenomenon of the curved-surface display panel.
Specifically, in the curved display panel provided by the embodiment of the present invention, as shown in fig. 8, the bending axis T of the curved display panel is located on a side of the first substrate 100 away from the second substrate 200;

Referring to fig. 8, the bending axis T is located on a side of the first substrate 100 away from the second substrate 200, and the first substrate 100 and the second substrate 200 protrude toward the direction in which the first substrate 100 points toward the second substrate 200. After the first substrate 100 and the second substrate 200 are bent after the box is assembled, one end of the spacer 103 close to the first substrate 100 will have a tendency to slide toward the center of the curved display panel, as shown in fig. 8, in the region to the left of the center line L3, one end of each spacer 103 near the first substrate 100 has a tendency to slide in the direction of the arrow S3, in the area to the right of the center line L3, each spacer 103 has a tendency to slide in the direction of arrow S4 at the end near the first substrate 103, the second stopper 400 may be provided at a side of the spacer 103 close to the center line L3 to effectively block the sliding of the spacer 103, specifically, in the region on the left side of the center line L3, each second stopper 400 is provided on one side of the corresponding spacer 103 in the S3 direction, in the region on the right side of the center line L3, each second stopper 400 is provided on one side of the corresponding spacer 103 in the S4 direction.

the second barrier 400 is located on the side of the spacer 103 facing away from the centerline L3.
Referring to fig. 9, the bending axis T is located on a side of the second substrate 200 away from the first substrate 100, and the first substrate 100 and the second substrate 200 protrude toward the second substrate 200 in a direction toward the first substrate 100. After the first substrate 100 and the second substrate 200 are bent after the box is assembled, one end of the spacer 103 close to the first substrate 100 will have a tendency to slide toward the edge of the curved display panel, as shown in fig. 9, in the region to the left of the center line L3, each spacer 103 has a tendency to slide in the direction of the arrow S1 at the end near the first substrate 100, in the area to the right of the center line L3, each spacer 103 has a tendency to slide in the direction of the arrow S2 at the end close to the first substrate 100, and thus, the second blocking portion 400 may be provided at a side of the spacer 103 facing away from the center line L3 to effectively block the sliding of the spacer 103, specifically, in the region on the left side of the center line L3, each second stopper 400 is provided on one side of the corresponding spacer 103 in the S1 direction, in the region on the right side of the center line L3, each second stopper 400 is provided on one side of the corresponding spacer 103 in the S2 direction.
In an alternative embodiment, as shown in fig. 5 and 6, under the condition that the space allows, the second blocking portion 105 may be disposed at a position close to the corresponding spacer 103, so as to ensure that the second blocking portion 105 can effectively block the corresponding spacer 103 from sliding, in a specific implementation, on the basis of ensuring that the second blocking portion 400 can effectively block the corresponding spacer 103 from sliding, the second blocking portion 400 may also have a certain distance from the corresponding spacer 103, where the specific position of the second blocking portion 400 is not limited.
Further, in the curved display panel according to the embodiment of the present invention, the rule of change of the size of each second barrier 400 is described by taking each second barrier shown in fig. 10 as an example, specifically, fig. 10 is a schematic diagram of each second barrier 400 in a right region of a center line L3 of the cross section shown in fig. 9, and each second barrier 400 shown in fig. 10 is located in the same cross section cut by a dotted line M in fig. 1.
It should be noted that, the second stoppers in the left area of the center line L3 in fig. 8, the second stoppers in the right area of the center line L3 in fig. 8, and the second stoppers in the left area of the center line L3 in fig. 9 also have a similar rule to the size of the second stoppers shown in fig. 10, and are not described in detail here.
In any cross section perpendicular to the curved display panel and parallel to the first edge, the height of the second barrier 400 in the direction perpendicular to the second substrate 200 is gradually increased in a direction in which the center line L3 points to the second edge L2 (the direction indicated by the arrow S2 in fig. 10); in fig. 10, the heights of the second stoppers 400 are H1 and H2 … … Hn, respectively, in the direction of the arrow S2, and H1 < H2 < … … < Hn;
and/or the presence of a gas in the gas,
in any cross section perpendicular to the curved display panel and parallel to the first edge L1, the width of the second barrier 400 in the direction in which the center line L3 points to the second edge L2 (the direction indicated by the arrow S2 in fig. 10) gradually increases in the direction in which the center line L3 points to the second edge L2, and in fig. 10, the width of each second barrier 400 in the direction of the arrow S2 is D1 and D2 … … Dn, respectively, and D1 < D2 < … … < Dn.
In a specific implementation, the height of the second barrier 400 may be set to be not more than two-thirds of the height of the spacer 103, specifically, the height of the spacer 103 is about 3 μm, the height of the second barrier 400 may be set to be in a range of 0.5 μm to 2 μm, or the height of each second barrier 400 may be set according to actual conditions, and the height value of the second barrier is not limited herein.
In practical applications, in order to avoid affecting the aperture ratio of the pixel unit, the spacer 103 and the second barrier 400 may be disposed in a non-open area of the pixel unit, and the spacer 103 may be disposed in a non-open area between adjacent pixel units, and thus, the second barrier 400 may be disposed in an area between the spacer 103 and the open area of the pixel unit, specifically, the width of the spacer 103 is about 9 μm, the distance between the edge of the spacer 103 and the open area is about 10 μm, and the width of the second barrier 400 may be set in a range of 5 μm to 10 μm to ensure that the second barrier 400 is located in the non-open area.
Referring also to fig. 10, in the direction of the arrow S2, the deformation amount of the spacers 103 at different positions is different, and specifically, in the direction in which the center line L3 points to the second edge L2, the deformation amount of the spacers 103 is greater, and therefore, the spacers 103 closer to the second edge L2 are more likely to slide, and therefore, in the direction in which the center line L3 points to the second edge L2, the size of each second blocking portion 400 is gradually increased, and the corresponding spacers 103 can be more effectively blocked from sliding, so that the dark-state light leakage phenomenon of the curved display panel can be avoided.
In addition, in any cross section perpendicular to the curved display panel and parallel to the second edge L2, the deformation amount of each spacer 103 is substantially the same, and thus, the height of each second barrier 400 may be set to be the same, and the width of each second barrier 400 may also be set to be the same.
In a specific implementation, as shown in fig. 11, fig. 11 is a schematic structural diagram of the curved display panel before being bent, where the first substrate 100 may further include: the second flat layer 102 is positioned on one side of the first substrate base plate 101 close to the second base plate 200;

By arranging a plurality of third protrusions W3 on the side of the second planarization 102 layer close to the second substrate 200 and the second barrier 400 including the third protrusions W3, the third protrusions W3 are formed on a certain film layer on the first substrate 101, so that the second barrier 400 has better stability, and the second barrier 400 is ensured to block the corresponding spacers 103 from sliding.
In an actual process, a plurality of third protrusions W3 are formed on a side of the second planarization layer 102 away from the first substrate 101, and then other film layers formed on a side of the second planarization layer 102 away from the first substrate 101 may also form protrusions along with the outline of the third protrusions W3, so that the second barrier 400 may further include protrusions formed by other film layers, for example, the second barrier 400 may further include protrusions formed by the first alignment layer 104 formed on a side of the second planarization layer 102 away from the first substrate 101, and in addition, the height of the second barrier 400 may also be increased by forming an insulating layer on a side of the second planarization layer 102 away from the first substrate 101, and in an actual application, the number of film layers in the second barrier 400 may be determined according to the height of the second barrier 400 to be formed.
In specific implementation, the thickness of the second blocking portion at different positions may be adjusted by using a halftone mask, or the thickness of the first blocking portion may also be adjusted by adjusting the number of film layers included in the second blocking portion at different positions, which is not limited herein.
