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 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.
