Display device and manufacturing method therefor

A display device comprising:

• a first substrate;
• and
• a second substrate including one surface opposite to one surface of the first substrate,
• wherein
• the first substrate comprises a first-one portion that overlaps the second substrate in a thickness direction and a first-two portion that does not overlap the second substrate,
• the second substrate comprises a second portion that overlaps the first substrate in the thickness direction,
• the first-two portion has a greater thickness than the first-one portion,
• the second portion comprises a second-one portion that overlaps the first-one portion in the thickness direction and a second-two portion disposed between the second-one portion and the first-two portion in a plan view,
• the second-two portion has a greater thickness than the second-one portion,
• the second-two portion is disposed so as not to overlap the first-two portion in the thickness direction,
• wherein the first-one portion comprises a first-one-one portion and a first-one-two portion disposed between the first-one-one portion and the first-two portion, and the first-one-one portion has a greater thickness than the first-one-two portion,
• wherein the second-one portion comprises a second-one-one portion disposed to overlap the first-one-one portion in the thickness direction and a second-one-two portion disposed to overlap the first-one-two portion in the thickness direction, and the second-one-one portion has a greater thickness than the second-one-two portion,
• wherein the first-one-one portion has a smaller thickness than the first-two portion and the second-one-one portion has a smaller thickness than the second-two portion, and
• wherein the first-one-two portion and the second-one-two portion are multi-etched regions, the first-one-one portion and the second-one-one portion are single-etched regions, and the first-two portion and the second-two portion are non-etched regions.
