Abstract
An image display device for repairing a scratch or scratches on a surface or surfaces of a light transmitting member having an image display section such an extent that the presence of the scratch or scratches cannot be visually perceived at at least in a bright view distance in all directions, and in which device a liquid filler having a refractive index equivalent to or on the same order of that of the light transmitting member is locally filled only into an area of the scratch or scratches, and the filler is cured. By controlling an amount of the filler so that a difference in level between a surface of the light transmitting member and a surface of the filler is at least ±5.0 &mgr;m or less and that an angle defined between a surface of the filler and a surface of the light transmitting member is at least 45 degrees or less or preferably at least 10 degrees or less, it is possible to exhibit display quality to such a degree that the presence of the scratch or scratches cannot be recognized.
