PROBLEM TO BE SOLVED: To obtain a laminated plate excellent in visible radiation transmittance and recognizability without deteriorating antireflection effect by forming an antireflection layer having a specified haze value on the surface of a transparent substrate. SOLUTION: The laminated plate for a filter used on the surface of VDT (video display terminal) has an antireflection layer 2 having 3.0-4.8% haze value on the surface of a transparent substrate 1. Since light undergoes moderate irregular reflection in the antireflection layer 2, the occurrence of reflection can be prevented and flicker generated at the VDT is blurred and made less liable to propagate, accordingly screen flicker is reduced and recognizability is enhanced. Since the attenuation rate of transmission of light is lower as compared with the case where many thin film layers of inorg. compds. are formed by the conventional vacuum deposition at the time of such an irregular reflection, the laminated plate is excellent in visible radiation transmittance and recognizability without deteriorating antireflection effect. |
