    Abstract: A display panel including a wavelength conversion structure that includes a base structure including partition walls that define a first space and a second space, a first quantum dot composite disposed in the first space, and a second quantum dot composite disposed in the second space. The height of the partition wall is greater than or equal to about 5 micrometers and less than or equal to about 50 micrometers, and the first quantum dot composite provides a first top surface and the second quantum dot composite provides a second top surface. A production method for making the wavelength conversion structure uses a first ink composition that includes first quantum dots and a first matrix, and a second ink composition that includes second quantum dots and a second matrix.

    Abstract: A color filter including a first pixel (or color conversion region) that is configured to emit a first light and a display device including the color filter. The first pixel includes a (first) quantum dot composite (or a color conversion layer including the quantum dot composite), wherein the quantum dot composite may include a matrix and a plurality of quantum dots dispersed (e.g., randomly) in the matrix, wherein the plurality of the quantum dots exhibit a multi-modal distribution (e.g., a bimodal distribution) including a first peak particle size and a second peak particle size in a size analysis, wherein the second peak particle size is greater than the first peak particle size, and a difference between the first peak particle size and the second peak particle size is less than or equal to about 5 nanometers (nm) (e.g., less than or equal to about 4.5 nm).

    Abstract: A quantum dot composite comprising: a matrix and a plurality of quantum dots dispersed in the matrix, wherein the plurality of the quantum dots comprises a semiconductor nanocrystal core including indium and phosphorous, a semiconductor nanocrystal shell disposed on the semiconductor nanocrystal core, and the semiconductor nanocrystal shell including zinc, selenium, and sulfur. The arithmetic size of the plurality of the quantum dots is greater than or equal to about 8 nm, wherein the quantum dot composite is configured to emit red light, and wherein when the quantum dot composite is irradiated with light of a wavelength of from about 450 nm to about 470 nm for a time period of less than or equal to about 500 hours, a luminance increase of the quantum dot composite is less than or equal to about 1.2% of an initial luminance of the quantum dot composite.
