    摘要: A backlight unit having a LED light source includes a light guide plate partitioned in areas each having a tapered shape formed of a thick portion and a thin portion. The light guide plate is formed such that a thick portion and a thin portion are repeated at certain intervals, and the repeated thick portions and the repeated thin portions gradually decrease in thickness. The LED light source is attached to a lateral side of each thick portion. Grooves are formed in the light irradiation direction of the LED light source and in a direction perpendicularly intersecting the light irradiation direction. Each of the grooves is formed in an concave shape (V-shape or trapezoid-shape). There is a relation 0.2/30

    摘要: In a projection type display apparatus using plural light sources, an optical unit including plural light sources, a first collimator lens, an optical coupling lens, an image display element and a projection lens is formed, and in an optical path extending from the light sources to the projection lens, light is condensed only once on the image display element, thereby minimizing the number of optical parts used and shortening the length of the optical path from the plural light sources up to the projection lens to attain the reduction in size of the projection type display apparatus or the optical unit.In this way it is possible to provide a projection type display apparatus or an optical unit each capable of attaining the reduction of cost by minimizing the number of optical parts used and capable of attaining a high luminance by irradiating the image display element with the light emitted from the light sources without leakage of the light.

    摘要: A projection type image display apparatus able to improve the utilization efficiency of light and attain a high luminance of light. An optical waveguide for guiding light emitted from a light source is provided, and a color separator for transmitting predetermined color light included in the light guided by the optical waveguide and for reflecting predetermined color light included in the guided light is also provided. The light reflected by the color separator is guided by the optical waveguide and is thereafter reflected by a reflecting member. The light reflected by the reflecting member is radiated into the optical waveguide and conducted thereby to the color separator.
