摘要: PROBLEM TO BE SOLVED: To provide an optical control sheet relaxed in processing tolerance and applicable to all light transmission plates while maintaining good utilization efficiency, a surface source device liquid crystal display device, which use the sheet. SOLUTION: Plural prism 13a 13b are formed on both surfaces of 13 so that generatrices 13g 13h made parallel each other. Then, beams incident one side emitted from other surface. Looking direction generatrix 13g, 13a, is surface, has two boundary 13c 13d having apex as boundary. Furthermore, unsummetrical shape with respect line, passes normal among into non-flat
