摘要: Provided are a display device and a fabrication method thereof. The display device includes a first substrate and a second substrate having one surface opposite to one surface of the first substrate. The first substrate includes 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 includes 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 includes 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.
