A display device includes: a display panel including an emission region, and a peripheral region adjacent to the emission region, the emission region including a light emitting element; at least one insulating layer on the display panel; an organic layer on the at least one insulating layer, the organic layer having an opening corresponding to the emission region; and a planarization layer on the organic layer, and filling the opening. The opening has a shape including first vertices and second vertices in a plan view, each of the first vertices has an internal angle of 90° or less, and in the plan view, each of the first vertices is located farther from a center of the opening than a corresponding adjacent second vertex from among the second vertices.

Display device

A display device includes a substrate, a plurality of first electrodes disposed on the substrate, a pixel defining layer disposed on the substrate, and defining a plurality of opening areas by exposing a portion of an upper surface of each of the plurality of first electrodes, a spacer disposed on the pixel defining layer and disposed between two adjacent opening areas among the plurality of opening areas, a groove extending into the spacer, a first common layer covering the plurality of first electrodes, the pixel defining layer, and the spacer, a plurality of light emitting layers disposed on the first common layer to overlap each of the plurality of opening areas, and a second electrode covering the plurality of light emitting layers and the first common layer. The groove at least partially overlaps with an imaginary straight line connecting two points located at the shortest distance between adjacent opening areas.

Display device with reduced crosstalk and manufacturing method of the same

A manufacturing apparatus and a manufacturing method are provided. A manufacturing apparatus includes a chamber, and a stage disposed in the chamber. The stage includes an upper surface on which a target substrate is disposed, a lower surface opposite to the upper surface, a first side surface extending between the upper surface and the lower surface in a first direction, and a second side surface extending between the upper surface and the lower surface in a second direction perpendicular to the first direction. The first side surface is in a round shape, and at least a portion of the first side surface is convex toward an outside of the stage.
