摘要	For a lighting device for obtaining output light in the wavelengths of light of three colors of red, green, and blue, a lighting device using a semiconductor laser for the blue light has been proposed. When using this lighting device in an image display device, etc., there are problems in blue color rendering properties and reduced image quality due to speckle noise. A light source device designed to emit red light, green light, a first blue light, and a second blue light, the light source device including: a red solid-state light source; a green solid-state light source; a semiconductor laser for emitting the first blue light; and a blue light generation part for emitting the second blue light, wherein the main component of the second blue light is light in a wavelength range of wavelengths longer than that of the first blue light.
其他摘要	对于用于获得红色，绿色和蓝色三种颜色的光的波长的输出光的照明装置，已经提出了一种使用半导体激光器用于蓝光的照明装置。当在图像显示装置等中使用该照明装置时，由于斑点噪声，存在蓝色显现特性和降低的图像质量的问题。一种光源装置，设计用于发射红光，绿光，第一蓝光和第二蓝光，该光源装置包括：红色固态光源;绿色固态光源;用于发射第一蓝光的半导体激光器;用于发射第二蓝光的蓝光产生部分，其中第二蓝光的主要成分是波长比第一蓝光长的波长范围内的光。
