In a possible embodiment, the first sealing layer 24 and the second sealing layer 26 may be implemented with a continuously extending spacer to seal around the periphery of the display area 10, however the continuously extending spacer is prone to affect performance and reliability when deformed. Therefore, the embodiments shown in fig. 8 to 10 are generally employed.

The liquid crystal display panel comprises a fifth spacer 17 and a sixth spacer 16 which are positioned outside the frame sealing glue 3, wherein the fifth spacer 17 is arranged on the first substrate 1 and extends from the first substrate 1 to the second substrate 2; the sixth spacer 16 is disposed on the second substrate 2 and extends from the second substrate 2 toward the first substrate 1; the fifth and sixth spacers 17, 16 are in end contact when facing the box. The fifth spacer 17 and the sixth spacer 16 may be disposed in the display region 10, and may further be disposed in a portion of the peripheral region where the frame sealing adhesive 3 is not disposed.

As shown in fig. 4, the first substrate 1 further includes an organic film 18, the organic film 18 extends from the display region 10 to the third wiring region 7, the frame sealing adhesive 3 covers the first wiring region 9 and the second wiring region 8, and does not extend to the organic film 18 in the third wiring region 7, and the fifth spacer 17 is disposed on a side of the organic film 18 close to the second substrate 2.

The gate driving circuit includes a driving transistor, and in a possible embodiment, the fifth spacer 17 is correspondingly disposed above the driving transistor, and a relatively flat surface can be provided on the top of the driving transistor, which is advantageous for the disposition of the fifth spacer 17.

In a possible embodiment, the sealant 3 extends to the position of the organic film 18 in the third wiring region 7, and the first spacer 14 is disposed on a side of the organic film 18 close to the second substrate 2, and may be correspondingly disposed on the top of the driving transistor.

In the related art, in order to avoid uneven thickness (Gap) of the peripheral box caused by the silicon balls 4 pressing on the organic film layer 18, and further cause Gap defects such as yellowing, a safety distance needs to be reserved between the frame sealing glue 3 and the edge of the organic film layer 18, but the reserved safety distance is not beneficial to reducing the display frame. In the liquid crystal display panel provided by the embodiment of the application, the spacer is adopted to replace the silicon balls 4, so that the frame sealing glue 3 can directly cover the organic film layer 18, the coating range of the frame sealing glue 3 can be larger, and the improvement of the firmness of box packaging and the reduction of the display frame distance are facilitated.

In the above embodiments, the display panel is taken as an example of a liquid crystal display panel, but the display panel provided in the embodiments of the present application is not limited to the liquid crystal display panel, and may also be other display panels including a first substrate and a second substrate, where the first substrate and the second substrate are paired with each other, such as an electrowetting display panel or an electrophoretic display panel. In the display panel, a first substrate and a second substrate are connected through frame sealing glue, a spacer is arranged in the frame sealing glue, and the spacer is adopted to replace silicon balls, so that spherical supports such as the silicon balls are avoided, and the possibility that the silicon balls crush lines is avoided; meanwhile, the silicon balls are replaced by the spacers, and the spacers can be manufactured on the same layer as the spacers in the display area, so that the manufacturing efficiency of the display panel can be improved, and the production cost can be reduced.

The embodiment of the application further provides a display device, the display device comprises the display panel in the embodiment, and the display device can be a mobile phone, a television, an electronic book, a digital sign, an intelligent doorplate, an electronic badge, a notebook computer, a tablet computer, a vehicle-mounted display, a touch control all-in-one machine and the like.
