    • A reflection type liquid crystal projector is provided which includes liquid crystal display panels (5R, 5G and 5B) to modulate color rays of light (R, G and B) corresponding to three primary colors (red, green and blue), respectively, on the basis of video data and a synthesizing prism (6) to synthesize the color rays of light (R, G and B) modulated by the liquid crystal display panels (5R, 5G and 5B) into one image. The liquid crystal display panel (5G) which provides an image inverted in relation to those provided by the liquid crystal display panels (5R and 5B) is aligned in a direction (X2) different from those (X1) in which the liquid crystal display panels (5R and 5B) are aligned, so that the alignment directions (X1 and X2) of the liquid crystal display panels (5R, 5G and 5B) will be coincident with each other in an image displayed on a screen (S). Thus, color staining can be prevented from taking place on the image resulted from synthesis of the color rays of light modulated by the liquid crystal display panels (5R, 5G and 5B).
    • 提供一种反射型液晶投影仪,其包括用于调制对应于三原色(红色,绿色和蓝色)的光(R,G和B)的彩色光线的液晶显示面板(5R,5G和5B) 分别基于视频数据和合成棱镜(6)将由液晶显示面板(5R,5G和5B)调制的光(R,G和B)的彩色光线合成为一个图像。 提供与由液晶显示面板(5R和5B)提供的图像相反的图像的液晶显示面板(5G)在与(X 1)不同的方向(X 2) 对准液晶显示面板(5R和5B),使得液晶显示面板(5R,5G和5B)的对准方向(X 1和X 2)将彼此一致 显示在屏幕(S)上的图像。 因此,可以防止由合成由液晶显示面板(5R,5G和5B)调制的光的颜色光合成的图像上发生着色。
