Abstract: 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.
