<p>PURPOSE:To make easier the adjustment of dimensions and positons between constitutional elements by a method in which optical axes between a light source, an optical guide, and a focusing type optical fiber are matched, and then optical axes between a liquid crystal light bulb and a focusing type optical fiber array are matched. CONSTITUTION:An aperture type fluorescent tube as a light source 1 and a light guide 2 are fixed under a condition that optical axes are matched at the time of assembly by using a binder 6. A focusing type optical fiber array 4 is connected through a binder 7 under a condition that the optical axis is matched with the light quide 2 in the guide hole 8 portion of the binder 6. A liquid crystal panel 3 is fixed by the binder 7 with a marginal space in the direction of (y). Thus, optical axes in the directionof (y) betwen the light source 1, the light guide 2, and the focusing type optical fiber array 4 can be adjusted, and the positions in the direction of (x) of the light source 1, the light guide 2, and the liquid crystal panel 3 can be adjusted at the time of assembly.</p> |
