摘要： Systems and methods are described for a display panel and a method of manufacturing the display panel. The systems and methods may provide for a substrate having a first surface and a second surface that face each other, a display unit including an organic light-emitting device arranged on the first surface of the substrate; and a thin-film encapsulation layer arranged on the display unit to shield the display unit, wherein an edge of the first surface or an edge of the second surface are inclined with respect to the first surface or the second surface. The inclined surfaces are designed to prevent damage to the display due to fine cracks during the manufacturing process as the display panel is trimmed or cut from a single base member. A display panel having improved strength characteristics may be manufactured, as well.

摘要： A method of manufacturing a display panel includes providing a work substrate including a first electrode and a pixel-defining layer including an opening exposing at least a part of the first electrode, forming a spacer on the pixel-defining layer, forming a light-emitting layer on the first electrode by providing a deposition material to a mask including a deposition opening corresponding to the opening, removing the mask, and compressing particles remaining on the spacer by a compression tool.
