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.
