Abstract: A display device is provided. An embodiment of a display device includes a first substrate, a second substrate disposed on the first substrate, first and second partition walls disposed on the second substrate, the second partition wall being disposed outside the first partition wall, a first trench disposed inside the first partition wall and having a first width, a second trench disposed between the first and second partition walls and having a second width greater than the first width; an alignment key disposed to overlap the second trench; a first spacer disposed on the alignment key, and a sealing member disposed along an edge between the first substrate and the second substrate without overlapping the alignment key, wherein the first spacer partially overlaps the first partition wall, the second partition wall, and the sealing member.

Abstract: A display device includes a first light emitting element on a first substrate and overlapping a first effective pixel area; test light emitting elements on the first substrate and overlapping the test pixel area; a first color filter on a second substrate and overlapping the first light emitting element; a first wavelength conversion pattern on the first color filter and overlapping the first color filter and the first light emitting element; a first test color filter on the second substrate and overlapping one of the test light emitting elements; and a first test wavelength conversion pattern on the second substrate and overlapping another one of the test light emitting elements. The first test wavelength conversion pattern and the first wavelength conversion pattern include a same first wavelength conversion material, and the first test color filter and the first color filter include a same first color colorant.
