Abstract: Disclosed are a wavelength conversion device, a light-emitting device and a projection system, comprising a wavelength conversion layer having a first surface and a second surface opposite each other. The first surface receives an excitation light. The wavelength conversion layer absorbs the excitation to produce a converted light and emits the converted light or the mixture of the converted light and the excitation light from the first surface and the second surface. A scattering reflective substrate is stacked with the wavelength conversion layer and includes a white porous ceramic or a white scattering material for scattering the incident light. The scattering reflective substrate includes a third surface facing the second surface and scatters at least a part of the incident light on the third surface and then emits all the light from the third surface to the second surface.

The light guide plate has a first surface, a second surface that is opposite to the first surface, at least one third surface, and a light incident surface. The third surface and the light incident surface are between the first and second surfaces. The third surface is adjacent to the light incident surface and has a concave-convex structure. The light source is located on the light incident surface. When the light source emits light, the light of the light source enters the light guide plate and transmits to the concave-convex structure, such that the light irradiates out from the concave-convex structure due to refraction, and is reflected back to the light guide plate by the concave-convex structure.
