<P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of suppressing and preventing the lowering of light beam transmissivity in the case of limiting a visual field angle, and smoothing, simplifying and facilitating assembly work or the like. <P>SOLUTION: Between the back light 1 of a car navigation device and the polarization film 41 of a liquid crystal panel 40, a transparent protective layer 10, a louver layer 20 and a mirror finished elastomer layer 30 are interposed. The louver layer 20 is integrally formed by alternately stacking a light transmitting layer 21 and a light shielding layer 22, the joined surface of the light transmitting layer 21 and the light shielding layer 22 is inclined at a prescribed angle to the thickness direction of the louver layer 20 and the louver layer 20 is tightly adhered through the mirror finished elastomer layer 30 to the liquid crystal panel 40. Since the louver layer 20 is tightly adhered to the liquid crystal panel 40 by the mirror finished elastomer layer 30 which is a tight adhesion layer, the need of sticking a transparent protective film to both surfaces of the louver layer 20 is eliminated and the transparent protective film is reduced. <P>COPYRIGHT: (C)2004,JPO |
