OPTICAL MEMBER, ILLUMINATING DEVICE USING THE SAME, DISPLAY DEVICE, AND TELEVISION RECEIVING DEVICE |
摘要 |
An optical member comprises a diffusion layer (13) diffusing emitted light from light sources (12), a first light collection layer (15), in which first projecting portions (15a) extending in a Y-direction are arranged at intervals (T1), refracting and collecting incident light from the diffusion layer (13), a first reflection layer (14) having first reflective portions (14a) facing boundaries between the adjacent first projecting portions (15a) and reflecting emitted light from the diffusion layer (13), a second light collection layer (17), in which second projecting portions (17a) extending in an X-direction are arranged at intervals (T2), refracting and collecting incident light from the first light collection layer (15), and a second reflection layer (16) having second reflective portions (16a) facing boundaries between the adjacent second projecting portions (17a) and reflecting emitted light from the first light collection layer (15).
