More Information
Summary:The present invention provides a louver sheet which comprises a resin film having a plurality of parallel trenches and a louver part which is made of louver materials and filled as at least embedding into the bottom of the trench, as well as rate of opening area is more than 80% viewing the direction being vertical to the first face of the resin sheet, the widest width W of the louver part is more than 0.1 m and below 5 m. Further, the rate of widest width W and height H (W/H) is more than 0.01 and below 0.2. The present invention provides a louver sheet which is capable of inhibiting effectively contrast resulted from external light and has a high full light transmissivity.
