Abstract
The embodiment of the present application discloses a liquid crystal display panel, the liquid crystal display panel includes a first substrate and a second substrate disposed opposite to each other. A frame sealant and a boss contacting each other are disposed in a frame sealant region, and the frame sealant at least partially overlaps the boss in a film thickness direction. A boss cooperating with the frame sealant to perform a sealing function is disposed in the frame sealant region. The boss reduces a volume of the frame sealant and lowers a time required for curing the frame sealant to improve a productivity.

A liquid crystal display panel, wherein the liquid crystal display panel comprises a display region and a frame sealant region surrounding the display region, and further comprises:
- a first substrate;
- a second substrate disposed opposite to the first substrate, wherein the first substrate comprises a first surface facing a side of the second substrate, and the second substrate comprises a second surface facing a side of the first substrate;
- wherein a sealing member is disposed between the frame sealant region, the first substrate and the second substrate, in a film thickness direction, an end of the sealing member is disposed on the first surface, another opposite end of the sealing member is disposed on the second surface, the sealing member is disposed linearly and continuously, the sealing member comprises a frame sealant and a boss in surface contact with each other, and the boss and the frame sealant at least partially overlap each other in the film thickness direction;
- wherein the first substrate is an array substrate, the array substrate comprises a first underlay, a passivation layer disposed on a side of the first underlay facing the second substrate, the frame sealant contacts the boss, the boss comprises a first boss disposed on the array substrate and laterally abutting the passivation layer, a height of the first boss relative to the first underlay is greater than a height of the passivation layer relative to the first underlay;
- the second substrate is a color filter substrate, the color filter substrate comprises a second underlay and a second planarization layer disposed on a side of the second underlay facing the array substrate, the frame sealant contacts the boss, the boss comprises a second boss disposed on the color filter substrate;
- wherein the array substrate further comprises a first planarization layer disposed on a side of the passivation layer facing the first underlay, and the first boss and the first planarization layer are disposed integrally;
- wherein manufacturing material of the first boss and manufacturing material of the first planarization layer are the same organic material;
- wherein the second boss and the second planarization layer are disposed integrally;
- wherein manufacturing material of the second boss and manufacturing material of the second planarization layer are the same organic material;
- wherein the first boss and the passivation layer are disposed integrally.
