In some embodiments, referring to fig. 1, the array substrate 100 includes a plurality of display regions 1 spaced apart from each other, and a peripheral region 2 located at the periphery of the display regions 1, the peripheral region 2 is provided with a gate 102, the color film substrate 200 includes a black matrix 201, the orthographic projection of the black matrix 201 on the array substrate 100 is located at the peripheral region 2, the peripheral region 2 is provided with a via hole 20, the display region 1 is provided with a conductive electrode 3, and the conductive electrode 3 extends to the peripheral region 2 and covers the via hole 20, that is, the peripheral region 2 and the display region 1 are both provided with the conductive electrode 3, the via hole 20 disposed in the peripheral region 2 is a through hole penetrating through the color resist layer 108, the second insulating layer 109 and the first insulating layer 107, the conductive electrode 3 is a pixel electrode, the pixel electrode covers the via hole 20 and is connected with the source 105, and the location where the pixel electrode is connected with the source 105 is located at the peripheral region 2.
In some embodiments, referring to fig. 1 to 5, a retaining wall 4 is disposed between the array substrate 100 and the color film substrate 200, and an orthographic projection of the retaining wall 4 on the array substrate 100 overlaps the conductive electrode 3 in the peripheral area 2, where the retaining wall 4 is used to block a portion of the liquid crystal corresponding to the via hole 20 from moving along a direction of an electric field generated by the conductive electrode 3.
Since the peripheral area 2 has the grid 102, and the black matrix 201 is disposed on the side of the color film substrate 200 to block the grid 102, so as to avoid affecting the display effect, when the backlight source irradiates, the grid 102 can block light, so that the liquid crystal corresponding to the peripheral area 2 cannot complete optical alignment, and the arrangement disorder occurs, especially the arrangement of the liquid crystal corresponding to the via hole 20 is more disordered, when the light is irradiated from the side of the color film substrate 200, the black matrix 201 can block the light, so that the liquid crystal corresponding to the peripheral area 2 cannot complete optical alignment, and the arrangement disorder occurs, especially the arrangement of the liquid crystal corresponding to the via hole 20 is more disordered, and when the screen is tapped, the disordered liquid crystal can easily move along the electric field direction of the pixel electrode, so as to appear in the display area 1, thereby forming scratch mura in the display area 1, and affecting the display effect. Through the arrangement, the retaining wall 4 is arranged between the array substrate 100 and the color film substrate 200, and the retaining wall 4 is arranged corresponding to the conductive electrode 3, so that part of the disorder liquid crystal moving along the direction of the electric field generated by the conductive electrode 3 is blocked by the retaining wall 4, the disorder liquid crystal moving towards the display area 1 is reduced, even no disorder liquid crystal moves to the display area 1, the problem that scratches Mura occur in the display area 1 is effectively solved, and the display effect is improved.
It should be noted that, the retaining wall 4 is used for blocking the movement of the liquid crystal corresponding to the via hole 20 into the display area 1, so that the retaining wall 4 needs to be disposed on the path of the movement of the liquid crystal corresponding to the via hole 20 into the display area 1, and thus the liquid crystal corresponding to the via hole 20 can be blocked to a certain extent, that is, the retaining wall 4 cannot be disposed adjacent to the edge of the side of the peripheral area 2 away from the display area 1, and the retaining wall 4 cannot be disposed between the via hole 20 and the edge of the side of the peripheral area 2 away from the display area 1, so that the retaining wall 4 is not disposed on the path of the liquid crystal corresponding to the via hole 20 moving into the display area 1, and thus the retaining wall 4 cannot play a role in blocking.
In some embodiments, referring to fig. 1, the retaining wall 4 is disposed on the array substrate 100, so that an alignment error of the color film substrate 200 can be effectively avoided, and an alignment error between the retaining wall 4 and the via hole 20 can be avoided. In the conventional display panel, the auxiliary spacer is disposed on the array substrate 100, and the auxiliary spacer is disposed in the peripheral area 2, wherein the via hole 20 is disposed between the auxiliary spacer and the display area 1, so that the liquid crystal disorder corresponding to the via hole 20 has no barrier on the path of moving to the display area 1, and the liquid crystal disorder corresponding to the via hole 20 easily moves to the scratch Mura in the display area 1; the retaining wall 4 in the first embodiment of the present application may be an auxiliary spacer, and only needs to adjust the standing position of the auxiliary spacer from the side of the via hole 20 away from the display area 1 to the side of the via hole 20 close to the display area 1 when the existing display panel is manufactured, so that the auxiliary spacer will be located on the path of the liquid crystal disorder corresponding to the via hole 20 moving toward the display area 1, thereby forming a blocking effect on the liquid crystal disorder, and thus, no additional material is required to set the retaining wall 4, and the working procedure is reduced, and the material and manufacturing cost are effectively reduced.
Specifically, since the retaining wall 4 has both the effect of blocking the disordered liquid crystal and the supporting effect of the auxiliary spacer, the original position of the auxiliary spacer cannot be used as the retaining wall 4, but the shape of the auxiliary spacer needs to be adjusted, the cross-sectional shape of the auxiliary spacer in the existing display panel is approximately square, in the first embodiment of the present application, the length of the auxiliary spacer serving as the retaining wall 4 can be adjusted to be three times the length of the existing auxiliary spacer, and the width of the auxiliary spacer serving as the retaining wall 4 can be adjusted to be one third of the width of the existing auxiliary spacer, so that the area of the top surface and the area of the bottom surface of the auxiliary spacer serving as the retaining wall 4 are respectively consistent with the area of the top surface and the area of the bottom surface of the existing auxiliary spacer, so that the supporting effect of the auxiliary spacer serving as the retaining wall 4 cannot be affected, and the top surface of the auxiliary spacer cannot be too sharp to hurt the color film substrate 200.
Of course, in order to further enhance the effect of blocking the liquid crystal disorder by the auxiliary spacer serving as the retaining wall 4, the length of the retaining wall 4 can be set longer within the allowable range of the setting space, so that the area of the top surface and the area of the bottom surface of the retaining wall 4 are larger than those of the top surface and the bottom surface of the existing auxiliary spacer, and the supporting effect of the auxiliary spacer serving as the retaining wall 4 can be enhanced, so that the top surface of the retaining wall 4 cannot stab the color film substrate 200.
In some embodiments, referring to fig. 4-5, a portion of the retaining wall 4 is located between the via 20 and the display area 1. Therefore, a part of retaining wall 4 exists between the via hole 20 and the display area 1, and the part of retaining wall 4 can block the corresponding disorder liquid crystal in the via hole 20 when the disorder liquid crystal moves to the display area 1, so that only the disorder liquid crystal between the retaining wall 4 and the display area 1 can possibly move into the display area 1, but the part of disorder liquid crystal is very little, even if the disorder liquid crystal moves into the display area 1 to cause scratches Mura, the scratches Mura are much less than those caused by the disorder liquid crystal moving into the display area 1 in the prior art, thereby effectively improving the problem that the scratches Mura occur in the display area 1 and improving the display effect.
In some embodiments, referring to fig. 4-5, the front projection of the retaining wall 4 on the array substrate 100 according to the first embodiment of the present disclosure is in a ring shape. That is, the retaining wall 4 is disposed in the edge area of the via hole 20, and the retaining wall 4 is disposed around the via hole 20, so that a portion of the retaining wall 4 is located between the via hole 20 and the display area 1, and the portion of the retaining wall 4 can block the liquid crystal corresponding to the via hole 20 from moving toward the display area 1.
The shape of the retaining wall 4 with the ring shape may be the same as the shape of the via hole 20, and of course, care should be taken that the ring width of the retaining wall 4 cannot be larger than the distance between the via hole 20 and the display area 1, so that the retaining wall 4 is located in the peripheral area 2 completely, and the aperture ratio of the display area 1 is not affected.
In some embodiments, referring to fig. 4, the front projection of the retaining wall 4 on the array substrate 100 may be an elliptical ring, or referring to fig. 5, the front projection of the retaining wall 4 on the array substrate 100 may also be a circular ring, or the front projection of the retaining wall 4 on the array substrate 100 may also be a ring with other shapes, which is not limited in this embodiment.
In some embodiments, referring to fig. 2-3, the retaining wall 4 is entirely located between the via 20 and the display area 1. Thus, when the liquid crystal corresponding to the via hole 20 moves towards the display area 1, the retaining wall 4 can block the liquid crystal, so that only the liquid crystal between the retaining wall 4 and the display area 1 can possibly move into the display area 1, but the liquid crystal is very little, even if the liquid crystal moves into the display area 1 to cause scratches Mura, the liquid crystal is much less than the scratches Mura caused by the liquid crystal moving into the display area 1 in the prior art, thereby effectively improving the problem that the scratches Mura appear in the display area 1 and improving the display effect.
It should be noted that, the length of the retaining wall 4 between the via hole 20 and the display area 1 in the direction perpendicular to the movement direction of the liquid crystal is required to be greater than the length of the via hole 20 in the direction perpendicular to the movement direction of the liquid crystal, so that more liquid crystal can be blocked as much as possible, specifically, the length of the retaining wall 4 between the via hole 20 and the display area 1 in the direction perpendicular to the movement direction of the liquid crystal is 3-4 micrometers longer than the length of the via hole 20 in the direction perpendicular to the movement direction of the liquid crystal, of course, the retaining wall 4 between the via hole 20 and the display area 1 also needs to meet that the orthographic projection of the liquid crystal opposite to the via hole 20 on the retaining wall 4 is located on the surface of the retaining wall 4 close to the via hole 20, so that the liquid crystal corresponding to the via hole 20 can be blocked by the retaining wall 4 in the movement process, the blocking effect of the liquid crystal to the liquid crystal can be enhanced, the liquid crystal moving to the display area 1 can be greatly reduced, and the problem of scratch Mura of the display area 1 can be effectively improved. Specifically, the orthographic projection of the liquid crystal turbulence opposite to the via hole 20 on the retaining wall 4 between the via hole 20 and the display area 1 can be located in the middle position of the retaining wall 4, which is close to one side surface of the via hole 20, so that the retaining wall 4 has the best blocking effect on the liquid crystal turbulence, and the overlong retaining wall 4 is not required to be arranged to waste the manufacturing material of the retaining wall 4, thereby saving the cost.
In some embodiments, referring to fig. 2, the front projection of the retaining wall 4 on the array substrate 100 in the first embodiment of the present application is in a strip shape, and the front projection of the strip shape extends along a first direction X, which is a direction perpendicular to the extending direction Y of the conductive electrode 3. This corresponds to the retaining wall 4 being perpendicular to the direction in which the liquid crystal is moved, so that the retaining wall 4 can better block the liquid crystal from moving to the display area 1.
In some embodiments, referring to fig. 3, the front projection of the retaining wall 4 on the array substrate 100 in the first embodiment of the present application is arc-shaped, and the front projection of the arc-shaped is convex along the extending direction Y of the conductive electrode 3 in the direction approaching the display area 1. Thus, the retaining wall 4 not only can play a role in blocking the movement of the disordered liquid crystal corresponding to the via hole 20 to the display area 1, but also the retaining wall 4 can not influence the aperture ratio of the display area 1.
In some embodiments, the retaining wall 4 is disposed adjacent to the edge of the via 20. Therefore, the retaining wall 4 can block more turbulence liquid crystals corresponding to the via holes 20, prevent the turbulence liquid crystals corresponding to the via holes 20 from moving into the display area 1, and effectively improve the problem that scratches Mura appear in the display area 1.
Because the retaining wall 4 of the first embodiment of the present application is obtained by adjusting the position of the auxiliary spacer in the existing display panel, the retaining wall 4 also has a supporting function, and when the screen is tapped by the above arrangement, the deformation of the display panel at the via hole 20 is reduced, so that the disorder liquid crystal corresponding to the via hole 20 is reduced, and the disorder liquid crystal in the display area 1 can be further reduced. Meanwhile, the arrangement can also avoid the influence of the deflection of the retaining wall 4 into the display area 1 during the arrangement on the aperture opening ratio of the display area 1.
In some embodiments, the retaining wall 4 is disposed adjacent to an edge of the display area 1. Therefore, no disorder liquid crystal exists between the retaining wall 4 and the display area 1, so that the retaining wall 4 can block more disorder liquid crystals corresponding to the peripheral area 2, and the phenomenon that the disorder liquid crystals move into the display area 1 to cause scratches Mura is avoided.
Example two
Referring to fig. 6 to 7, the display panel according to the second embodiment of the present application is different from the first embodiment only in that the spacers 5 are also disposed at the same positions where the spacers 5 are disposed in the conventional display panel. In the second embodiment of the present application, the retaining wall 4 may be disposed on the basis of the existing display panel, and the manufacturing material of the retaining wall 4 is the same as that of the spacer 5 of the existing display panel, so that the effect of blocking the movement of the liquid crystal corresponding to the via hole 20 to the display area 1 can be achieved only by adding the retaining wall 4 without changing the existing display panel.
It should be noted that, the spacer 5 of the existing display panel is disposed on the array substrate 100, so that the retaining wall 4 and the spacer 5 are disposed on the same side, and thus the retaining wall 4 and the spacer 5 of the display panel can be simultaneously disposed, and the spacer 5 and the retaining wall 4 are simultaneously manufactured through one photomask, so that the manufacturing process is reduced, the manufacturing efficiency is improved, the manufacturing cost of additional photomasks is saved, and the cost is reduced. The retaining wall 4 can be used as an auxiliary spacer, so that the number of the auxiliary spacers of the display panel can be increased, and the supporting effect on the color film substrate 200 and the array substrate 100 can be improved.
Example III
Referring to fig. 8 to 9, the display panel according to the third embodiment of the present application is different from the first embodiment only in the arrangement position of the retaining wall 4. In the third embodiment of the present application, the retaining wall 4 is disposed on the color film substrate 200, and the orthographic projection of the retaining wall 4 on the array substrate 100 overlaps the via hole 20. In other words, in the thickness direction of the array substrate 100, the retaining wall 4 is opposite to the via hole 20, so that the area between the via hole 20 and the color film substrate 200 is occupied by the retaining wall 4, and therefore, the disorder liquid crystal corresponding to the via hole 20 is reduced, the disorder liquid crystal moving towards the display area 1 is reduced, the disorder liquid crystal is not easy to move into the display area 1, and the problem of scratch Mura in the display area 1 is effectively improved.
It should be noted that, since the retaining wall 4 in the second embodiment of the present application is used for blocking the movement of the liquid crystal with disorder corresponding to the via hole 20 to the display area 1, the retaining wall 4 needs to be disposed on the path along which the liquid crystal with disorder moves to the display area 1, and when the length of the retaining wall 4 in the direction perpendicular to the moving direction of the liquid crystal with disorder is less than or equal to the length of the via hole 20 in the direction perpendicular to the moving direction of the liquid crystal with disorder, the orthographic projection of the retaining wall 4 on the array substrate 100 will be located in the via hole 20, so that when the screen is tapped or pressed, the retaining wall 4 disposed on the color film substrate 200 will sink into the via hole 20 to damage the conductive electrode 3 in the via hole 20. In the second embodiment of the present application, the length of the retaining wall 4 in the direction perpendicular to the moving direction of the liquid crystal is greater than the length of the via hole 20 in the direction perpendicular to the moving direction of the liquid crystal, so when the screen is tapped or pressed, the retaining wall 4 disposed on the color film substrate 200 will be lapped on the edge area of the via hole 20, and the conductive electrode 3 in the via hole 20 will not be damaged by sinking into the via hole 20.
Example IV
Referring to fig. 10 to 11, the display panel provided in the fourth embodiment of the present application is different from the three-phase display panel in that the setting positions of the retaining walls 4 on the color film substrate 200 are different. In the fourth embodiment of the present application, the front projection of the retaining wall 4 on the array substrate 100 covers the via hole 20. In other words, in the thickness direction of the array substrate 100, the retaining wall 4 is opposite to the via hole 20, so that the area between the via hole 20 and the color film substrate 200 is occupied by the retaining wall 4, and therefore, the disorder liquid crystal corresponding to the via hole 20 is reduced, the disorder liquid crystal moving towards the display area 1 is reduced, the disorder liquid crystal is not easy to move into the display area 1, and the problem of scratch Mura in the display area 1 is effectively improved.
It should be noted that, in the fourth embodiment of the present application, the area of the surface of the retaining wall 4 near the side of the array substrate 100 is larger than the aperture area of the via hole 20, when the screen is tapped or pressed, the surface of the retaining wall 4 near the side of the array substrate 100 will abut against the edge area of the via hole 20 and cover the via hole 20, so that the retaining wall 4 will not sink into the via hole 20 to damage the conductive electrode 3, and the via hole 20 is blocked to effectively eliminate the disordered liquid crystal corresponding to the via hole 20, thereby being not easy to move to the display area 1, and effectively improving the problem of the scratch Mura of the display area 1.
It can be understood that, the alignment error is easy to occur when the retaining wall 4 is disposed on the color film substrate 200 side, so that in order to make the front projection of the retaining wall 4 on the array substrate 100 cover the via hole 20 to eliminate the disordered liquid crystal corresponding to the via hole 20, the area of the surface of the retaining wall 4 near the side of the array substrate 100 needs to be designed to be larger than the aperture area of the via hole 20, so that even if there is some alignment error, the surface of the retaining wall 4 near the side of the array substrate 100 can cover the aperture of the via hole 20.
In the fourth embodiment of the present application, the retaining wall 4 may be an auxiliary spacer, so the area of the surface of the retaining wall 4 on the side of the color film substrate 200 is larger than the area of the surface of the retaining wall 4 on the side of the retaining wall 4 close to the array substrate 100, when the area of the surface of the retaining wall 4 on the side of the retaining wall 4 close to the array substrate 100 becomes larger so as to better cover the via hole 20, the area of the surface of the retaining wall 4 on the side of the color film substrate 200 will be larger, so the area of the surface of the retaining wall 4 close to the side of the array substrate 100 can be slightly larger than the area of the surface of the retaining wall 4 close to the side of the array substrate 100 in the alignment error range, and no excessive area of the surface of the retaining wall 4 towards the array substrate 100 is required, and the manufacturing material of the retaining wall 4 can be reduced, so the cost is reduced.
Example five
Referring to fig. 12, the display panel provided in the fifth embodiment of the present application is different from the three-phase embodiment only in that the setting position of the retaining wall 4 on the color film substrate 200 is different. In the fifth embodiment of the present application, the orthographic projection of the retaining wall 4 on the array substrate 100 is located between the via hole 20 and the display area 1. Thus, the liquid crystal disorder corresponding to the via hole 20 is blocked by the retaining wall 4 when moving to the display area 1, so that the liquid crystal disorder is not easy to move to the display area 1 and scratches Mura occur.
In some embodiments, the orthographic projection of the retaining wall 4 on the array substrate 100 is adjacent to the edge of the via hole 20, so that the retaining wall 4 can block more turbulent liquid crystals corresponding to the via hole 20, prevent the turbulent liquid crystals corresponding to the via hole 20 from moving into the display area 1, and effectively improve the problem of scratch Mura of the display area 1.
In some embodiments, the front projection of the retaining wall 4 on the array substrate 100 is adjacent to the edge of the display area 1, so that no turbulent liquid crystal exists between the retaining wall 4 and the display area 1, so that the retaining wall 4 can block more turbulent liquid crystal corresponding to the peripheral area 2, and the turbulent liquid crystal is prevented from moving into the display area 1 to generate scratches Mura.
Example six
Referring to fig. 13, the display panel provided in the sixth embodiment of the present application is different from the fourth embodiment only in that the spacers 5 are also provided at the same positions where the spacers 5 are provided in the existing display panel. In the sixth embodiment of the present application, the retaining wall 4 may be disposed on the basis of the existing display panel, that is, the retaining wall 4 is disposed on the basis that the spacer 5 has been disposed on the existing display panel, and the manufacturing material of the retaining wall 4 is the same as that of the spacer 5 of the existing display panel, so that the effect of blocking the movement of the liquid crystal corresponding to the via hole 20 to the display area 1 can be achieved only by adding the retaining wall 4. The retaining wall 4 can be used as an auxiliary spacer, so that the number of the auxiliary spacers of the display panel can be increased, and the supporting effect on the color film substrate 200 and the array substrate 100 can be improved.
In some embodiments, the spacer 5 of the existing display panel is disposed on the array substrate 100, and the retaining wall 4 is disposed on the color film substrate 200, so that the structure of the existing display panel is not required to be changed, the retaining wall 4 may be disposed on the color film substrate 200, or the spacer 5 may be disposed on the array substrate 100 and the retaining wall 4 may be disposed on the color film substrate 200 during manufacturing the display panel, so that the manufacturing time of the display panel is not lengthened and the manufacturing efficiency of the display panel is not affected.
In some embodiments, the spacer 5 of the display panel may be disposed on the color film substrate 200, so that the spacer 5 and the retaining wall 4 are disposed on the same side, and the spacer 5 and the retaining wall 4 may be simultaneously disposed, and the spacer 5 and the retaining wall 4 are simultaneously manufactured through one photomask, so that the manufacturing process is reduced, the manufacturing efficiency is improved, the manufacturing cost of additional photomasks is also saved, and the cost is reduced.
