Abstract: PURPOSE:To improve luminance in a normal direction and to improve the uniformity of the luminance by disposing specially shaped prismatic lenses on one surface of a transparent base material by mutually setting the edges thereof in parallel and making the other surface flat. CONSTITUTION:The film lens 1 is the lens for controlling output light used on the output side of a surface light source used for a display or the like. The prismatic lenses 3 obtained by shaping the apex angles of the main cut cross sections to be almost 90 deg. and forming a triangular apex angle part and/or the vicinity of the bottom part of a side interposing the apex angle to be circular are disposed on one surface of the transparent base material 2 by mutually setting the edges thereof in parallel. Besides, the other surface of the material 2 is made flat. Then, the luminance of the output light is improved by preventing the total retroreflection of the light made incident near the apex and/or near the bottom part out of the whole isosceles triangular prism of about 90 deg. from occurring and distributing the light to the output light. Besides, since the light is reflected on the light reflection surface of a lamp house and distributed to the other part of the lens 1 and one part of the distributed light is outputted, the distribution of the luminance in an output surface is uniformized.
