## Abstract

A display apparatus includes a first substrate corresponding to an active area, and a sealing area surrounding the active area, a second substrate facing the first substrate, a display portion in the active area, a sealing member in the sealing area between the first substrate and the second substrate, and a guide mark on one surface of the second substrate in an area where the sealing member and the second substrate overlap each other.

## Claims

### Claim 1

A display apparatus comprising:
a first substrate corresponding to an active area, and a sealing area surrounding the active area;
a second substrate facing the first substrate;
a display portion in the active area;
a sealing member in the sealing area between the first substrate and the second substrate; and
a guide mark on one surface of the second substrate in an area where the sealing member and the second substrate overlap each other, the guide mark being more narrow than the sealing member with respect to a direction in which the guide mark and the sealing member extend in a plan view,
wherein the guide mark comprises a plurality of marks each extending in a lengthwise direction of the sealing member, and
wherein the plurality of marks are apart from each other in the lengthwise direction of the sealing member.

### Claim 2 (depends on 1)

The display apparatus of claim 1, wherein the guide mark comprises:
a plurality of first marks along a virtual first row extending in a lengthwise direction of the sealing member; and
a plurality of second marks along a virtual second row extending in the lengthwise direction of the sealing member.

### Claim 3 (depends on 2)

The display apparatus of claim 2, wherein a distance between the virtual first row and the virtual second row is substantially constant.

### Claim 4 (depends on 1)

The display apparatus of claim 1, wherein a distance between a center of the guide mark and the active area is less than a distance between a center of the sealing member and the active area.

### Claim 5 (depends on 1)

The display apparatus of claim 1, wherein the guide mark comprises a heat-resistant material.

### Claim 6

A display apparatus comprising:
a first substrate corresponding to an active area, and a sealing area surrounding the active area;
a second substrate facing the first substrate;
a display portion in the active area;
a sealing member in the sealing area between the first substrate and the second substrate;
a guide mark on one surface of the second substrate in an area where the sealing member and the second substrate overlap each other; and
a touch screen wiring on an outer surface of the second substrate that is opposite to an inner surface of the second substrate contacting the sealing member,
wherein the guide mark is arranged on the outer surface of the second substrate.

### Claim 7 (depends on 6)

The display apparatus of claim 6, wherein the guide mark comprises a same material as a material of the touch screen wiring.

### Claim 8 (depends on 6)

The display apparatus of claim 6, wherein the guide mark extends in a lengthwise direction of the sealing member.
