Abstract
A wavelength conversion module including a substrate and a wavelength conversion layer is provided. The substrate includes an axis, and the axis is located at the center of the substrate. The wavelength conversion layer is located on the substrate and includes two first wavelength conversion layers and a second wavelength conversion layer. Each of the first wavelength conversion layers includes a wavelength conversion material and a first bonding material. The second wavelength conversion layer is located between the two first wavelength conversion layers in a radial direction from the axis of the substrate to an edge of the substrate, and the second wavelength conversion layer includes the wavelength conversion material and a second bonding material. The first bonding material is different from the second bonding material. Moreover, a projection device and a forming method of the wavelength conversion module are also provided.
