摘要： A light source device comprising: a light source section which generates any one of blue light, red light, and green light; a phosphor which generates a fluorescence including the two colors other than the color of the light emitted from the light source section; a color-changing section which changes one of the two colors of the fluorescence emitted from the phosphor to another color regularly and irradiates it to the image-forming element; and a light path-switching section which switches a light path in which a fluorescence excited by the color light emitted from the light source section passes towards the color-changing section and a light path in which the color light emitted from the light source section passes towards the image-forming element regularly.

摘要： A scanning image displayer, including a beam provider emitting a laser beam; a beam scanner including a two-dimensional drive deflecting mirror, deflectively scanning the beam in a main scanning direction and a sub-scanning direction; and an optical element including a reflection surface before the two-dimensional drive deflecting mirror, deflecting the beam in a direction of the two-dimensional drive deflecting mirror such that the beam obliquely enters a mirror thereof. The two-dimensional drive deflecting mirror deflectively scans the beam to project the beam onto a surface to be projected, and the light intensity of the beam is controlled according to image information to form an image. A flat surface of a substrate where the mirror is formed is located parallel or almost parallel to an optical axis of the beam, and the reflection surface is located so as not to receive the beam deflectively scanned by the two-dimensional drive deflecting mirror.
