## Abstract

A method for fabricating liquid crystal display panels. The method includes forming at least one adhesive structure on a first substrate, to partition the first substrate into at least one dummy region and panel group regions, in which the dummy region is located between the two adjacent panel group regions; pouring liquid crystal into the dummy region and the panel group regions; and conjugating a second substrate at a side of the first substrate disposed with the adhesive structure, to seal spaces of the dummy region and the panel group regions between the first substrate and the second substrate, in which the liquid crystal can fill up the spaces of the panel group regions and at least a part of the spaces of the dummy region being sealed between the first substrate and the second substrate.

## Claims

### Claim 1

A method for fabricating liquid crystal display panels, comprising:
forming at least one adhesive structure comprising a plurality of barrier portions on a first substrate, to partition the first substrate into at least one dummy region and a plurality of panel group regions, wherein all of the dummy region is located between two adjacent panel group regions and surrounded by the barrier portions, the dummy region is separated from the panel group regions by parts of the barrier portions, and the panel group is defined by at least one side of the barrier portions and at least one side of the dummy region;
pouring liquid crystal into the dummy region and the panel group regions; and
conjugating a second substrate at a side of the first substrate disposed with the adhesive structure, to seal spaces of the dummy region and the panel group regions between the first substrate and the second substrate, wherein the liquid crystal fills up the spaces of the panel group regions and at least a part of the dummy region sealed between the first substrate and the second substrate.

### Claim 2 (depends on 1)

The method of claim 1, wherein at least part of the adhesive structure are composed by the barrier portions.

### Claim 3 (depends on 2)

The method of claim 2, wherein pouring the liquid crystal into the dummy region and the panel group regions is pouring the liquid crystal to fill up spaces of the barrier portions sealing between the first substrate and the second substrate.

### Claim 4 (depends on 2)

The method of claim 2, wherein any of the two adjacent panel group regions have one of the barrier portions disposed inbetween.

### Claim 5 (depends on 2)

The method of claim 2, wherein any of the two adjacent panel group regions have a plurality of the barrier portions disposed inbetween.

### Claim 6 (depends on 5)

The method of claim 5, wherein the barrier portions disposed between two adjacent panel group regions have a gap between any of two adjacent barrier portions.

### Claim 7 (depends on 1)

The method of claim 1, wherein forming the adhesive structure on the first substrate comprises:
coating a curable adhesive on the first substrate, to partition the dummy region and the panel group regions; and
curing the curable adhesive, to form the adhesive structure.

### Claim 8 (depends on 7)

The method of claim 7, wherein forming the adhesive structure on the first substrate further comprises:
coating the curable adhesive inside at least a part of the dummy region on the first substrate.

### Claim 9 (depends on 7)

The method of claim 7, wherein the curable adhesive is a light-curing adhesive or a heat-curing adhesive.

### Claim 10 (depends on 1)

The method of claim 1, further comprising forming a thin film transistor array on a surface of the second substrate opposite to the first substrate.

### Claim 11 (depends on 1)

The method of claim 1, further comprising forming a touch sensing layer on a surface of the first substrate opposite to the second substrate.

### Claim 12 (depends on 1)

The method of claim 1, wherein the panel group regions comprise a plurality of liquid crystal display panels, and the method further comprises cutting the panel group regions, to fabricate the liquid crystal display panels.
