In the sealant region 200, at least one through hole 101 is formed in the black matrix 22 and the second electrode 23 to expose the second substrate 21, and the through hole 101 may be formed by a laser method. The sealant 30 is directly connected and fixed to the second substrate 21 in the through hole 101, and the sealant 30 is still connected and fixed to the second electrode 23 in the region outside the through hole 101.
As shown in fig. 1, in the current liquid crystal display panel, in the whole frame glue area 200, the frame glue 30 is connected to the second substrate 21 through the second electrode 23 and the black matrix 22, since the black matrix 22 itself is a loose structure, when the display panel receives external acting forces such as pulling force, the black matrix is the weakest link, and water vapor is more likely to invade into the display area from this point, causing a short circuit of the display, which is more serious for the liquid crystal display panel with an ultra-narrow frame. In the liquid crystal display panel of the present application, since the black matrix 22 is not present at the through hole 101, and a loose structure is not present, the connection with the second substrate 21 is firmer, the water vapor blocking capability at this position is improved, and in the region outside the through hole 101, a part of the black matrix 22 is still retained, and the remaining black matrix 22 can still play a role in preventing light leakage. That is, the liquid crystal display panel of this application has realized leak protection light and has prevented compromise of steam invasion.
The through-holes 101 are arranged in various ways.
In one embodiment, as shown in fig. 3, the through holes 101 form a ring structure around the display area. At this time, on all the paths of the display area 100 pointing to the sealant area 200, a part of the black matrix 22 is removed, so that the sealant 30 is directly connected to the second substrate 21, and thus the moisture at any position outside the entire display area 100 can be blocked, and the remaining black matrix 22 is also in an annular structure, so that any position outside the entire display area 100 can also have the effect of preventing light leakage.
In one embodiment, as shown in fig. 4, the liquid crystal display panel includes a plurality of through holes 101 disposed at intervals, and the plurality of through holes 101 form a ring structure around the display area 100. At this moment, regional steam in each through-hole 101 is blockked, can prevent the light leak in black matrix 22 place region, and for the annular structure that whole through-hole 101 formed, surplus black matrix 22 is more in this embodiment to when having realized that certain degree steam blocks the ability and promotes, also guaranteed the effect that prevents the light leak.
In one embodiment, as shown in FIG. 5, the plurality of through holes 101 are staggered. Two or more rows of through holes 101 are formed on each side of the liquid crystal display panel, each row of through holes 101 includes a plurality of through holes 101 arranged at intervals, and the two or more rows are in a staggered shape and still have an annular structure as a whole. On the premise that the total number of the through holes 101 is equal, when only one row of through holes 101 arranged at intervals is arranged, the distance between the through holes 101 is relatively small, so that the width of the residual black matrix 22 between the two through holes 101 is also small, and the light leakage prevention effect is limited. When the through holes 101 are arranged in a staggered manner, the distance between every two adjacent through holes 101 is relatively large, and the width of the residual black matrix 22 between every two adjacent through holes 101 is relatively large, so that the water vapor blocking capability is ensured, and the light leakage prevention effect is improved.
In one embodiment, as shown in fig. 6, at least two through holes 101 are provided at intervals in a direction from the display area 100 to the sealant area 200. At this time, on the path of the water vapor invasion from outside to inside, two or more through holes 101 can play a double or multiple blocking role, and the water vapor blocking capability is further improved.
In one embodiment, the width of the black matrix 22 between two adjacent through holes 101 is not less than the width of the through holes 101. As shown in fig. 7, the width of the black matrix 22 between two adjacent through holes 101 is represented by d1, the width of the through hole 101 is represented by d2, and d1 is set to be greater than or equal to d2, so that the light leakage prevention effect can be ensured, and the improvement of the water vapor blocking capability can be realized under the premise.
In one embodiment, the via 101 includes a top surface 10 proximate to the second substrate 21 and a bottom surface 20 distal to the second substrate 21, the top surface 10 having a width greater than a width of the bottom surface 20. As shown in fig. 7, the cross section of the through hole 101 is an inverted trapezoid, and since the width of the top surface 10 is large, the contact area between the sealant 30 and the second substrate 21 is increased, the connection effect is firmer, and the vapor blocking effect is further improved.
In one embodiment, the thickness of the black matrix 22 in the sealant region 200 is greater than the thickness in the display region. As shown in fig. 7, the thickness h of the black matrix 22 is represented by h, and due to the existence of the through hole 101, the total width of the black matrix 22 in the frame glue region 200 is reduced, the light leakage prevention capability is reduced, and the thickness h of the black matrix 22 in the region can be increased, so that the light leakage prevention capability can be improved to a certain extent.
In one embodiment, the frame glue area 200 includes a frame glue area and a corner glue area, and the through hole 101 is disposed in the frame glue area, but not disposed in the corner glue area. The liquid crystal display panel comprises a plurality of edges and a plurality of corners, the frame glue area corresponds to each edge, and the corner frame glue area corresponds to each corner. In the frame gluey district, need avoid the light of a side to reveal in the display area 100 to reveal, and in the frame district is glued to the limit, need avoid the light of two sides to reveal in the display area 100 to reveal simultaneously, consequently the frame district is glued to the limit is bigger some to the demand that prevents the light leak, can only set up through-hole 101 in the frame district is glued to the limit to indicate steam to block the ability, remains original black matrix 22 in the frame district is glued to the limit, ensures the light leak protection ability here.
