Display device and manufacturing method thereof

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

• providing a first substrate, the first substrate comprising a display area in which a plurality of pixels are formed and a non-display area in which an internal circuit unit electrically connected to the pixels is formed, the non-display area surrounding the display area;
• forming a sealing material in the non-display area of the first substrate, a portion of the sealing material overlapping the internal circuit unit;
• placing a second substrate above the first substrate, the second substrate having a groove formed at a position corresponding to the portion of the sealing material;
• and
• curing the sealing material.

A display device, comprising:

• first and second substrates each comprising a display area and a non-display area adjacent to the display area;
• an internal circuit unit formed in the non-display area;
• and
• a sealing member formed between the non-display areas of the first and second substrates to surround the display areas,
• wherein the sealing member comprises a first portion and a second portion, and
• wherein a first distance between the first and second substrates corresponding to the first portion of the sealing member is less than a second distance between the first and second substrates corresponding to the second portion of the sealing member
