Abstract: A display device and a method of manufacturing the display device are capable of substantially minimizing damage and carbonization of a substrate, the display device including: a substrate including a first area and a second area disposed in a first direction and including at least one layer disposed along a second direction intersecting the first direction; a display layer in the first area of the substrate; a functional member on the display layer in the first area of the substrate; and a driving unit in the second area of the substrate, the driving unit configured to drive the display layer. Said at least one layer includes a first end portion at the first area of the substrate and a second end portion at the second area of the substrate, and the first end portion has a greater surface roughness than a surface roughness of the second end portion.

Abstract: A method of manufacturing a display apparatus includes separating a mother substrate that includes a plurality of connected unit display apparatuses into a plurality of separated unit display apparatuses. Each separated unit display apparatus includes a display panel and at least one supporting unit attached below the display panel. The display panel includes a display substrate that has a pad area on which are disposed a plurality of pads and a thin film encapsulation layer on the display substrate. The method further includes consecutively cutting the display panel and the at least one supporting unit of each separated unit display apparatus along cutting lines in the pad area, where a first cut surface of the pad area of the display substrate and a second cut surface of the at least one supporting unit are respectively cut at different angles.

Abstract: A display device in which damage and carbonization of a display substrate is substantially minimized and a method of manufacturing the display device are provided. A display device includes: a substrate including a first area having a first thickness and a second area having a second thickness which is different from the first thickness; a display layer at the first area of the substrate; and a functional member on the display layer at the first area. The first area and the second area are arranged along a first direction, the substrate includes a protruding portion at the second area, and the protruding portion includes a side portion having an inclination of about 5 degrees or more with respect to the first direction toward a second direction which intersects the first direction.
