Abstract
A wavelength conversion element including a substrate, a blocking wall structure layer, and a wavelength conversion layer is provided. The blocking wall structure layer is disposed on a surface of the substrate and defines multiple microgrooves. Reflectivity of the blocking wall structure layer is in a range of 1% to 99%. The wavelength conversion layer is disposed in the microgrooves and includes multiple wavelength conversion particles. A height of the blocking wall structure layer along a normal direction of the surface of the substrate is greater than a height of the wavelength conversion layer along the normal direction of the surface of the substrate. A backlight module adopting the wavelength conversion element is also provided.
