More Information
Summary: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.
