Optical laminated bodies, lighting equipment and area luminescence equipment |
摘要 |
Lighting devices are disclosed that include optical laminated bodies. An exemplary optical laminated body includes a polarizing layer, a first transparent film disposed closely to a front surface of the polarizing layer and a second transparent film disposed closely to a back surface of the polarizing layer. The polarizing layer includes a reflective polarizing film, and both of the first transparent film and the second transparent film are diffusive films. The lighting devices further include a light source supplying light to the optical laminated body through a light entry surface of the first transparent film of the optical laminated body and a lens film disposed between the light source and the optical laminated body. The lighting device provides diffused-polarized light emitted from a light emitting surface of the second transparent film of the laminated body.
