Title:
PLANAR LIGHT SOURCE DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/148177
Kind Code:
A1
Abstract:
A planar light source device (100) provided with laser light sources (21, 22), first light-guide elements (40, 50), and a second light-guide element (70). The laser light sources (21, 22) emit laser light beams. The first light-guide elements (40, 50) mix the plurality of laser light beams (25, 26) emitted from the laser light sources (21, 22) and convert the plurality of laser light beams (25, 26) into linear light. The second light-guide element (70) receives the linear light and converts the linear light into planar light. The laser light sources (21, 22) are disposed in regions (48, 58) separated by the first light-guide elements (40, 50). The planar light source device (100) radiates heat released in the regions (48, 58) from the laser light sources (21, 22).
