光学构件，使用其的照明装置，显示装置和电视接收装置

Optical member, illuminating device using the same, display device, and television receiving device
Abstract:
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).
Abstract(Chinese):

光学构件包括漫射来自光源（12）的发射光的扩散层（13），第一光收集层（15），其中沿Y方向延伸的第一突出部分（15a）以间隔（T1）布​​置， ，从所述扩散层（13）折射和收集入射光;第一反射层（14），其具有面对所述相邻的第一突出部分（15a）之间的边界的第一反射部分（14a）并且反射来自所述扩散层（13）的发射光; ，第二聚光层（17），其中沿X方向延伸的第二突出部分（17a）以间隔（T2）排列，折射和收集来自第一光收集层（15）的入射光，第二聚光层 反射层（16）具有与相邻的第二突出部分（17a）之间的边界相对的第二反射部分（16a）并反射来自第一光收集层（15）的发射光。
