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： A light guide plate includes a body portion, first unit optical elements extending on the body portion in the light guide direction, and second unit optical elements disposed in between the first unit optical elements on the body portion. The width of each first unit optical element gradually decreases from that at the center to that at each end in the light guide direction. The ratio of the height to the width in each first unit optical element at the center is higher than the ratio of the height to the width in each second unit optical element.
