摘要：
A light-transmitting layer is formed on a transparent glass panel, the light-transmitting layer having a larger refractive index than that of the glass panel, and a light-absorbing layer having a light-transmitting region is formed on the light-transmitting layer. The light reflected from the interface of the glass panel and the light-absorbing layer is effectively attenuated by the light-transmitting layer, so that it is possible to obtain an excellent image having a considerably strong contrast.
