Display device and method of manufacturing the same

A method of manufacturing a display device, the method comprising:

• providing a first substrate;
• providing a second substrate on the first substrate, the second substrate including a display region, a first non-display region in the display region and a second non-display region outside the display region;
• forming a pixel array layer on the display region of the second substrate;
• forming a separation hole and an encapsulation groove in the first non-display region of the second substrate;
• forming an encapsulation layer on the display region and the first and second non-display regions of the second substrate, wherein an inner wall of the separation hole and an inner wall of the encapsulation groove are at least partially covered with the encapsulation layer;
• and
• separating the first substrate from the second substrate;
• wherein in the separating of the first substrate from the second substrate, the pixel array layer and the second substrate inside the separation hole are separated together with the first substrate, and a remaining through hole is formed in the second substrate, and
• an end face of the encapsulation layer formed on the inner wall of the separation hole when the first substrate is separated from the second substrate has an irregular shape.

A display device, comprising:

• a first substrate;
• a second substrate comprising an organic layer and an inorganic layer disposed on the first substrate;
• an encapsulation groove formed in the second substrate, wherein the encapsulation groove comprises a plurality of holes formed in the second substrate;
• a through hole penetrating the second substrate, wherein the through hole has a greater depth than a depth of the encapsulation groove toward the first substrate, and wherein the through hole is spaced apart from the encapsulation groove;
• and
• an encapsulation layer formed on an inner sidewall of the encapsulation groove and on an inner sidewall of the through hole.
