ILLUMINATING APPARATUS AND DISPLAY APPARATUS |
摘要 |
An illuminating apparatus is provided and includes a plurality of point light sources in one plane and a first optical sheet and a second optical sheet overlapped in a region facing the plurality of point light sources. The plurality of point light sources are arranged in a first direction and also arranged in a second direction orthogonal to the first direction. The first optical sheet has a plurality of first three-dimensional structures extending in a direction parallel to the first direction and arranged in a direction parallel to the second direction. The second optical sheet has a plurality of second three-dimensional structures extending in a direction parallel to the second direction and arranged in a direction parallel to the first direction. Each of the second three-dimensional structures has a shape which generates a larger amount of return light from normal incident light as compared with the first three-dimensional structures.
