Referring to fig. 3, when the first alignment layer 24 is printed without offset, the rubber frame 50 covers each of the first alignment layers

The edge of the first alignment block 242 and the rubber frame 50 are formed into a complete ring shape on the outer edge of the first substrate 20, so as to block the first alignment film 24 from external moisture, and improve the moisture-proof performance of the liquid crystal display panel.

Second embodiment

Referring to fig. 8, a second embodiment of the present invention provides a narrow-frame lcd panel, which is different from the first embodiment in that the first alignment block 242 is in a shape of a Chinese character 'tu', and includes a first rectangle 242a and a second rectangle 242b connected to each other, a first side of the first rectangle 242a is connected to a second side of the second rectangle 242b, the first side is wider than the second side, and the second rectangle 242b is closer to the outer edge of the glue filling area SA than the first rectangle 242 a.

Preferably, the length L1 of the first side is 25 μm to 45 μm, the length L3 of the third side perpendicular to the first side in the first rectangle 242a is 45 μm to 70 μm, the length L2 of the second side is 15 μm to 20 μm, the length L4 of the fourth side perpendicular to the second side in the second rectangle 242b is 30 μm to 55 μm, and the distance L5 between two nearest points of two adjacent first alignment blocks 242 in the same row is 20 μm to 50 μm.

For example, the length L1 of the first side is 40 μm, the length L3 of the third side perpendicular to the first side in the first rectangle 242a is 60 μm, the length L2 of the second side is 20 μm, the length L4 of the fourth side perpendicular to the second side in the second rectangle 242b is 40 μm, and the distance L5 between two nearest points of two adjacent first alignment blocks 242 in the same row is 24 μm.

Compared with the inside of the glue area SA, the adhesive strength and the water vapor resistance near the outer edge of the glue area SA have a greater influence on the overall performance of the liquid crystal display panel, and in the area near the outer edge of the glue area SA, the area ratio of the direct contact between the glue frame 50 and the insulating layer 23 is increased by the convex first alignment blocks 242, so that the packaging strength and the water vapor resistance of the liquid crystal display panel are optimized.

Also, when the first alignment film 24 is printed, the shift that generally occurs in the first direction X and/or the second direction Y is generally small. As shown in fig. 8, when the printing of the first alignment film 24 is shifted by the third distance X3 in the first direction X, a small shift of 0-60 μm X3 occurs more frequently than a larger shift, and at the outer edge of the glue region SA, the area of the glue frame 50 in direct contact with the insulating layer 23 is larger than the area of the glue frame 50 in direct contact with the first alignment film 24, so that the adverse effect of the printing shift of the first alignment film 24 on the package strength and the moisture resistance is reduced.

Based on the precision of the transfer printing plate 60, the too small area of the single first alignment block 242 may cause insufficient absorption of alignment liquid in the edge pattern 62, which may cause printing defects, and the convex first alignment block 242 is adopted in the embodiment, so that the packaging strength and the moisture resistance of the liquid crystal display panel are improved under the precision of the existing transfer printing plate 60.

Further, the shape of the first alignment block 242 may take any number of rectangular, circular, semicircular, trapezoidal, or convex shapes. For example: referring to fig. 9, in the four sides of the area of the rubber frame 50, the row of the first alignment blocks 242 closest to the outer edge of the adhesive area SA is convex, and the remaining first alignment blocks 242 are rectangular.

During the curing process of the first alignment film 24, a certain degree of shrinkage may occur, and the outwardly protruding structure provides a portion of the alignment liquid to the first middle alignment region 241 during the shrinkage process, and provides a surface tension, so as to reduce the shrinkage range of the first middle alignment region 241 and avoid the occurrence of poor display at the edge of the display region AA.

The utility model also provides a liquid crystal display device, including the liquid crystal display panel of any kind of above-mentioned narrow frame.
