PROBLEM TO BE SOLVED: To provide a light control sheet which has a light focusing property of making a front surface direction sufficiently bright when a liquid crystal display element, etc., are used and a divergent property that the sheet is visible evenly bright if within a visual field angle range of some extent in combination and prevents the visibility of surface defects, such as flaws, and a light emitting device having such sheet. SOLUTION: The light control sheet 31 is molded by using an aluminum embossing roll 12 subjected to an anodic oxidation treatment on the roll surface. Its front surface 32 has many approximately parallel corrugations. These corrugations are worked with fine ruggedness in such a manner that the center line average height thereof attains 0.1 to 1μm The rear surface 36 is formed as an optical plane or the plane is worked with the fine ruggedness.
