20130083403VIRTUAL IMAGE DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME - 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.04-04-2013
