    • In a virtual image display device, a mirror layer has a thickness of 50 nm or more to perform non-transparent reflection in a second ridge line vicinity area on a third reflection face side in a ridge line portion extending between the third reflection face and a second reflection face. Accordingly, reflectance of image light can be prevented from being decreased by the second ridge line vicinity area (that is, a peripheral portion on a light guide unit in the third reflection face), and thus stripe-shaped brightness unevenness extending in a longitudinal direction can be prevented from occurring on the viewed image. That is, in the image display device, it is possible to secure sufficient reflection even in the peripheral portion close to a boundary with the second reflection face with respect to the third reflection face, and also to display a bright image with little brightness unevenness.
    • 在虚像显示装置中,镜层的厚度为50nm以上,在第3反射面和第3反射面之间延伸的棱线部分的第3反射面侧的第2脊线附近区域进行非透明反射 第二反射面。 因此,可以防止图像光的反射率被第二脊线附近区域(即,第三反射面中的导光单元的周边部分)减小,并且因此在纵向方向上延伸的条形亮度不均匀 可以防止在观看图像上发生。 也就是说,在图像显示装置中,即使在靠近与第二反射面相对于第三反射面的边界的周边部分中也可以确保足够的反射,并且还可以显示亮度不均匀的亮度图像。
