Abstract: A display apparatus includes: a first area; a first bent area outside the first area, the first bent area being bent about a first bending axis; and a second bent area outside the first area, the second bent area being adjacent to an edge of the first area extending in a direction crossing the first bending axis, and being bent about a second bending axis that is parallel with an imaginary line extending in a direction crossing the first bending axis. A cut-off portion extends into the first area, the cut-off portion being at a portion where a first line crosses a second line, the first line being parallel with the first bending axis and passing through the first bent area, and the second line being parallel with the second bending axis and passing through the second bent area.

Abstract: A display module including a display panel, a supporting member, a first circuit board, and a light blocking member. The display panel includes a display area and a non-display area. The non-display area is bent. The supporting member includes a first surface overlapping the display area; a second surface opposite to the first surface; and a third surface configured to connect the first surface to the second surface. The first circuit board faces the second surface and is electrically connected to the non-display area. The light blocking member contacts a bent area of the non-display area.

Abstract: A display device may include a light-emitting element and a controllable element. The light-emitting element may emit a light. The controllable element may neighbor the light-emitting element in a plan view of the display device and may include a fluid set. The fluid set may include at least one of a light-reflecting element set and a black element set. The controllable element may have a first average reflectance value in a first direction if the controllable element receives no voltage or receives a first voltage. The controllable element may have a second average reflectance value in the first direction if the controllable element receives a second voltage. The second voltage may be unequal to the first voltage. The second average reflectance value may be unequal to the first average reflectance value.
