<p>PROBLEM TO BE SOLVED: To provide a member for regulating the optical path direction of display light for vehicles capable of surely preventing the arrival of the image light having variations in the light quantity toward directions unnecessary for visual recognizing this image light even when such image light is emitted from plural display surfaces to be illuminated and even if the image light of different directions is emitted from the respective display surfaces and a process for producing this member for regulating the optical path direction of display light for vehicles adequate for use at the time of producing the member for regulating the optical path direction of display light for vehicles. SOLUTION: Louvers 60 are formed on works 50 by a screen printing method, offset printing method and vapor deposition method. Light shielding layers 61a of the thickness h1 smaller than low walls 61B lowest in the height H1 from the forming surfaces 50a of the light shielding parts 61 of the louvers 60 and light shielding materials are laminated by as much as the number meeting the heights H1, H3, H5 from the respective forming surfaces 50a of the high walls 61A, low walls 61B and middle walls 61C, by which the louvers 60 are formed on the works 50.</p> |
