    • An image display apparatus is disclosed which includes: an optical system including a light source and at least one projection lens; a display means for forming a display image, the display means including a non-luminescent display panel and a microlens array disposed on the light-incidence side of the display panel; and at least one projection lens for projecting the display image; wherein the display panel and the microlens array are combined with each other by means of an adhesive made of a transparent material. In cases where the microlens array is provided with color filters which are arranged so as to correspond to the microlenses of this array, the image display apparatus can provide a bright display of color images with an improved contrast. Moreover, when the display panel and the microlens array are combined with each other by means of an adhesive containing spacers, the image display apparatus has a high thermal reliability.
    • 公开了一种图像显示装置,其包括:包括光源和至少一个投影透镜的光学系统; 用于形成显示图像的显示装置,所述显示装置包括非发光显示面板和设置在所述显示面板的光入射侧的微透镜阵列; 和至少一个用于投影显示图像的投影透镜; 其中显示面板和微透镜阵列通过由透明材料制成的粘合剂彼此组合。 在微透镜阵列设置有与该阵列的微透镜相对应的滤色器的情况下,图像显示装置可以提供具有改善的对比度的彩色图像的明亮显示。 此外,当显示面板和微透镜阵列通过含有间隔物的粘合剂彼此组合时,图像显示装置具有高的热可靠性。
