Abstract
The present disclosure provide methods of manufacturing a liquid crystal display panel and the liquid crystal display panels. In a process of forming a motherboard of the display panel, a second sealant portion and a third sealant portion with a lower height than that of a first sealant portion are temporarily formed outside the first sealant portion, so that a smooth transitional support surface is formed between the first sealant portion, the second sealant portion, the third sealant portion and a support column inside the panel.
Claims19
A method of manufacturing a liquid crystal display panel, comprising:
- providing an upper cover plate of which at least one daughter board area and a cutting area located outside the daughter board area are defined;
- arranging a first sealant portion at an edge of the daughter board area close to the cutting area;
- arranging a second sealant portion and at least one third sealant portion in the cutting area, wherein a long side of each of the second sealant portion and the third sealant portion is in a same direction as the edge of the daughter board area;
- arranging a lower substrate opposite to the upper cover plate to cover at least the daughter board area and the cutting area, to form a motherboard;
- and
- cutting the motherboard to remove the cutting area, to form at least one independent daughter board;
- wherein the at least one daughter board area comprises at least a first daughter board area, the second sealant portion and the at least one third sealant portion are arranged along both short sides of the first daughter board area;
- wherein the at least one daughter board area comprises a second daughter board area and a third daughter board area close to a short side of the first daughter board area, the first daughter board area is larger than a sum of the second daughter board area and the third daughter board area, and a side of each of the second daughter board area and the third daughter board area close to the first daughter board area has an equal straight-line distance from the first daughter board area.
