## Abstract

The exemplary embodiments relate generally to a display device that may include: a first substrate and a second substrate, each including a transparent encapsulation area; an outer sealant along a side of the transparent encapsulation area; a pattern part disposed on the first substrate and extending in a direction parallel to the outer sealant; and a transparent sealant adjacent to the pattern part and extending in a direction parallel to the pattern part, and a manufacturing method thereof.

## Claims

### Claim at position 1

-10. (canceled)

### Claim 11

A method for manufacturing a display device, the method comprising:
forming a pattern part extending in a direction along a side of a transparent encapsulation area of a first substrate or a second substrate;
forming an outer sealant parallel to the pattern part;
forming a transparent sealant adjacent to the pattern part and extending in a direction parallel to the pattern part; and
sealing the first substrate and the second substrate,
wherein forming the transparent sealant is performed such that the transparent substrate has a predetermined interval with the outer sealant and fills between the first substrate and the second substrate.

### Claim 12 (depends on 11)

The method as claimed in claim 11, wherein
forming the transparent sealant is performed by a one-time process.

### Claim 13 (depends on 11)

The method as claimed in claim 11, wherein
forming the pattern part is simultaneously performed with a step of forming a color filter in a display area of the first substrate that displays an image.

### Claim 14 (depends on 11)

The method as claimed in claim 11, wherein
forming the pattern part is simultaneously performed with a step of forming a column spacer in a display area of the first substrate that displays an image.
