LIGHT DIFFUSION PLATE, SURFACE LIGHT SOURCE DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a light diffusion plate having sufficient strength and heat resistance and small in the linear expansion coefficient and anisotropy to prevent the deformation even under a sever heating condition. <P>SOLUTION: The light diffusion plate 3 contains 0.01-2.0 pts.mass cyclic aliphatic carboxylic metal salt based on 100 pts.mass propylene resin. The light diffusion plate 3 constitutes a liquid crystal display device 30, together with: a surface light source device 1 having a light source 2 arranged on the backside of the light diffusion plate; and a liquid crystal panel 20. <P>COPYRIGHT: (C)2011,JPO&INPIT |
