Abstract
A wavelength conversion device including a main body and a transparent element is provided. The main body has at least one wavelength conversion region, a containing recess portion, and a stop portion. The containing recess portion and the stop portion encircle a closed slot. The transparent element is disposed in the closed slot to construct a light penetration region. The stop portion stops the transparent element along a radial direction of the main body. Moreover, a projector using the wavelength conversion device is also mentioned.
