摘要
To provide a projector which enables a stable projection for a long period of time, there is provided a projector comprising a light source unit, a display device, a projection-side optical system, a light guiding optical system and a projector control unit, wherein the light source unit comprises an excitation light source unit comprising an excitation light source and a microlens array and a rectangular green luminescent plate which receives light emitted from the excitation light source to emit light in a green wavelength band, and the microlens array is disposed between the excitation light source and the luminescent plate and has a plurality of micro convex lenses which each have a similar shape to the shape of the luminescent material layer are arranged into a matrix, so as to convert light from excitation light source into a plurality of pencils of light to shine them onto the luminescent plate.
