摘要： A manufacturing method of a wavelength-converting component includes providing a substrate, providing a wavelength-converting layer and providing a reflective layer. The reflective layer is disposed on the substrate. The wavelength-converting layer is disposed on a surface of the reflective layer away from the substrate. The wavelength-converting layer includes a wavelength-converting material and a second organic adhesive. The wavelength-converting material is mixed in the second organic adhesive. The second organic adhesive includes an aromatic polyimide. The wavelength-converting component manufactured by the method of the invention can improve mechanical properties such as shear strength, tensile strength and fatigue strength, temperature resistance and reflectivity, and can reduce rates of moisture absorption. The projection apparatus including the wavelength-converting component can reduce degradation in image brightness.

摘要： A wavelength-converting component includes a substrate, a wavelength-converting layer and a reflective layer. The wavelength-converting layer is disposed on the substrate. The reflective layer is disposed between the substrate and the wavelength-converting layer. The reflective layer includes a plurality of diffuse reflection particles and a first organic adhesive. The diffuse reflection particles are mixed in the first organic adhesive. The first organic adhesive includes an aromatic polyimide. The invention further provides a projection apparatus using the wavelength-converting component and provides a manufacturing method of the wavelength-converting component. The wavelength-converting component of the invention can improve mechanical properties such as shear strength, tensile strength and fatigue strength, temperature resistance and reflectivity, and can reduce rates of moisture absorption. The projection apparatus of the invention can reduce degradation in image brightness.
