## Abstract

The present disclosure provides a display substrate and a method for manufacturing the same, and a display device. The display substrate includes a display area and an edge area surrounding the display area. The edge area is provided with bonding adhesive. The bonding adhesive is used to bond the display substrate and a counter substrate with which the display substrate is to be assembled together. A support structure is provided on the edge area and on a side of the bonding adhesive away from the display area. The support structure forms support between the display substrate and the counter substrate which have been assembled with each other.

## Claims

### Claim 1

A display substrate, comprising
a display area,
an edge area surrounding the display area,
a bonding adhesive at the edge area which is configured to bond the display substrate and a counter substrate with which the display substrate is to be assembled, and
a support structure on the edge area and on a side of the bonding adhesive away from the display area, wherein the support structure is configured to form support between the display substrate and the counter substrate which have been assembled with each other,
wherein a shape of a cross section of the support structure perpendicular to an extending direction of the display substrate on which the support structure is located is a trapezoid, and a bottom surface of the support structure having a larger area is in contact with the display substrate.

### Claim 2 (depends on 1)

The display substrate of claim 1, wherein a gap exists between the support structure and the bonding adhesive.

### Claim 3 (depends on 2)

The display substrate of claim 2, wherein a width of the gap is substantially equal to 30˜50 μm.

### Claim 4 (depends on 1)

The display substrate of claim 1, wherein a height of the support structure is less than a height of the bonding adhesive before the display substrate and the counter substrate are bonded.

### Claim 5 (depends on 1)

The display substrate of claim 1, wherein the bonding adhesive comprises glass cement.

### Claim 6 (depends on 1)

The display substrate of claim 1, wherein the display area is further provided with a spacer.

### Claim 7 (depends on 6)

The display substrate of claim 6, wherein a material of the support structure is the same as a material of the spacer.

### Claim 8 (depends on 6)

The display substrate of claim 6, wherein a height of the support structure is the same as a height of the spacer.

### Claim 9 (depends on 1)

The display substrate of claim 1, wherein a spacing between two adjacent ones of a plurality of the support structures spaced from each other is substantially equal to 5˜10 μm.

### Claim 10 (depends on 1)

The display substrate of claim 1, wherein the counter substrate is an array substrate.

### Claim 11 (depends on 1)

The display substrate of claim 1, wherein the display substrate is a packaging cover plate or a color film substrate.

### Claim 12 (depends on 1)

A display device, comprising the display substrate according to claim 1.

### Claim 13

A method for manufacturing a display substrate which comprises a display area and an edge area, comprising:
coating the edge area with bonding adhesive,
providing a support structure on the edge area and on a side of the bonding adhesive away from the display area, wherein a shape of a cross section of the support structure perpendicular to an extending direction of the display substrate on which the support structure is located is a trapezoid, and a bottom surface of the support structure having a larger area is in contact with the display substrate, and
sintering the bonding adhesive.
