摘要： The present invention provides a surface light source device and a transmission display device, which can exhibit smoother output light properties and higher front luminance, and avoid occurrence of moiré. A surface light source device 10A includes a light source portion 13A, a light controlling sheet 15 located on the output light side of the light source portion 13A, and a light diffusing sheet 16 located on the output light side of the light controlling sheet 15 and including micro-convex structures. The light diffusing sheet 16 includes a transparent base film 16a, and a light diffusing layer 16d coated on a surface of the transparent base film 16a. Micro-beads 16b incorporated in the light diffusion sheet 16 can exhibit a lens effect and provide a light condensing effect and a light diffusing effect. As such, the output light properties of the surface light source device 10A can be changed smoother, thereby providing higher front luminance and avoiding occurrence of moiré.

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.
