Abstract: A display panel includes: a light emitting device layer including a light emitting area to emit a first color light; a partition layer on the light emitting device layer, and having a first opening overlapping with the light emitting area, and a second opening adjacent to the first opening; and a light control pattern located in the first opening to convert the first color light to a second color light. The partition layer includes: a first partition defining the first opening; a second partition extending from the first partition, and defining the second opening; and a junction area corresponding to a location where the second partition is joined to the first partition adjacent thereto. The junction area includes a first-side area, and a second-side area having an asymmetric shape with respect to the first-side area based on an extending direction in which the second partition extends.
