An organic light emitting display device may include a flexible substrate, a common layer, and an encapsulation member. An undercut groove may be formed on the flexible substrate. The common layer may be disposed on the flexible substrate, may include an organic light emitting layer, and may be disconnected by the groove. The encapsulation member may be disposed on the common layer, and may cover the common layer.

A material-removing heater device including: a first terminal portion defining a first electrode; a second terminal portion defining a second electrode; and a heating portion which connects the first terminal portion to the second terminal portion, the heating portion heatable by a flow of electrical current from the first terminal portion to the second terminal portion to remove a portion of material of a display device. The heating portion defines a lower end surface of the material-removing heater device at which the material-removing heater device contacts the material of the display device, the heating portion disposes the lower end surface to have a concave shape, and the heating portion which is heated deforms the lower end surface from the concave shape to have a planar shape.

Material-removing heater device

An organic light emitting diode display device includes a lower substrate, a plurality of lower electrodes, a light emitting layer, an upper electrode, and a first functional module. The lower substrate includes a first module region that includes sub-pixel regions and transmissive regions, and a display region that surrounds the first module region and includes the sub-pixel regions. The lower electrodes are respectively disposed on the lower substrate in the sub-pixel regions in the first module region. The light emitting layer is disposed on the lower electrodes, and includes a first opening between two adjacent lower electrodes. The upper electrode is disposed on the light emitting layer, and includes a second opening that overlaps the first opening. The first functional module is disposed on a bottom surface of the lower substrate in the first module region.
