摘要：PURPOSE: To improve transmittance for light and to decrease the production cost by forming a rugged pattern on both sides of a sheet so that enough condensing effect is obtd. in one sheet. CONSTITUTION: A rugged pattern necessary to form a prism is formed on both sides of a sheet 1 in such a manner that the ridge lines of prisms on top and back sides are perpendicular to each other. In this case, light is condensed in the plane perpendicular to the ridge of the prism on each surface. Namely, light can be
condensed in the vertical direction and the horizontal direction. Thus, light is condensed on both surfaces of the prism sheet 1 in contact with air in the plane perpendicular to each other (perpendicular to each of the prism ridge) so that light can be efficiently
condensed. Thereby, the effect to condense light in the vertical and horizontal directions can be performed in one prism sheet l, which improves the brightness and decreases manhour and the production cost.
