Abstract: A display device includes a first substrate, pixel structures, and first, second, and third optical filters. The first substrate has a plurality of pixel regions each including first, second, and third sub-pixel regions. The pixel structures are disposed on the first substrate. The first, second, and third optical filters are disposed to overlap the first, second, and third sub-pixel regions, respectively, on the pixel structures. Each of the first, second, and third optical filters has a tetragon shape. A long axis of the tetragon is parallel to row or column directions of the pixel regions. The third optical filter overlaps a first virtual line located between a side of the first optical filter and a side of the second optical filter which is adjacent to the side of the first optical filter. The first virtual line extends parallel to the sides of the first and second optical filters.

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.
