Abstract: An apparatus for manufacturing a display device includes a moving part including a belt that circulates, a roller that circulates the belt, and at least one meandering prevention portion that moves in a first direction parallel to a direction of a rotation shaft of the roller and prevents meandering of the belt, and a polishing head disposed corresponding to the moving part, the polishing head polishing a surface of a base material disposed on a first surface of the belt. A part of the at least one meandering prevention portion faces a second surface of the belt, the second surface being a side surface of the belt.

Abstract: A nano-imprinting stamp may include a base substrate, an imprint pattern provided on the base substrate, and an alignment pattern provided on the base substrate adjacent to the imprint pattern, the alignment pattern, each of which has a different shape from the imprint pattern. The base substrate may include a groove region formed between the imprint pattern and the alignment pattern in which a top surface of the imprint pattern being lower than a bottom surface of the alignment pattern.

Abstract: A display apparatus includes a display layer, an encapsulation layer, and a reflective layer. The display layer is on a substrate and includes a non-emission area adjacent to an emission area. The encapsulation layer is over the display layer. The reflective layer is on the encapsulation layer and includes a first opening corresponding to the emission area and a reflecting area adjacent the first opening and corresponding to the non-emission area. The reflective layer transmits light in a first mode and reflects light in a second mode different from the first mode.
