Abstract: A display device includes: a base substrate including an opening area, an opening peripheral area, and a display area at least partially surrounding the opening peripheral area, wherein the opening peripheral area is a non-display area at least partially surrounding the opening area; a thin film transistor disposed on the base substrate in the display area; a via insulating layer disposed on the thin film transistor and having a first opening surrounding the opening area, wherein the first opening is in the opening peripheral area; a pixel defining layer disposed on the via insulating layer and having a first opening which overlaps the first opening of the via insulating layer; a transparent filler disposed on the base substrate in the opening area; and a sealing substrate disposed on the transparent filler.

Abstract: A display device includes: a first substrate including: a display area including a plurality of pixels, and a peripheral area positioned around the display area; a thin film transistor positioned on the first substrate; a pixel electrode layer positioned on the thin film transistor and including more than one pixel electrodes positioned in the display area; and a pixel definition layer positioned on the pixel electrode layer and including a peripheral portion overlapping a voltage transmission electrode. The peripheral portion includes a spacer and an inclination portion connected to the spacer and positioned at a first side of the spacer, and the inclination portion has a concave inclination surface.

Abstract: An electrostatic spray printing apparatus includes a nozzle, a first voltage supply, and two guide electrodes. The nozzle sprays a solution containing an organic material. The first voltage supply divides the solution sprayed from the nozzle into fine droplets by applying a positive voltage to the nozzle. The guide electrodes are arranged to be spaced apart from each other with an end of the nozzle therebetween, extends in a first direction, and are grounded. The electrostatic spray printing apparatus forms an organic pattern with a uniform thickness.
