摘要： An optical sheet is incorporated in a direct type surface light source device including a light source and is configured to allow light emitted from the light source to exit after changing a travel direction of the light. The optical sheet has a light exiting side lens part including unit lenses juxtaposed to one another and each unit lens is convex toward a light exiting side. A light scattering layer, configured to scatter the light, is provided to each unit lens. The light scattering layer extends along a light exiting side surface of each convex unit lens and constitutes the light exiting side surface of the unit lens. A thickness of the light scattering layer around an apex portion of each unit lens is greater than the thickness of the light scattering layer around each end portion of the unit lens.

摘要： An optical sheet (40) includes a body portion (42) and unit shaped elements (45) arranged side-by-side on a light outgoing side of the body portion, each of the unit shaped elements extending linearly in a direction intersecting the arrangement direction. Each of the unit shaped elements has a tapered cross-sectional shape in a main cross-section. In a main cross-section, the angle of the tangent to either end of the outline of each unit shaped element with respect to the sheet plane of the body portion is not less than 55° and not more than 75°. The optical sheet makes it possible to enhance the efficiency in the use of source light, thereby effectively enhancing the front direction luminance.
