LCD display protection board |
| abstract |
The present invention provides a liquid crystal display protection sheet capable of suppressing reduction in visibility, such as rainbow streaks, black screen, and coloring, when a liquid crystal display protection sheet positioned on a liquid crystal screen is observed through a polarizing filter. The liquid crystal display protective plate (1) of the present invention includes a resin plate (16) in which a base material layer (22) is laminated on both surfaces of a retardation adjusting layer (21). The retardation adjusting layer contains a transparent thermoplastic resin (A) having an absolute value of photoelastic coefficient of 10.0×10 −12 /Pa or less and an absolute value of orientation birefringence of 10.0×10 −4 to 100.0×10 −4 . The base material layer contains a transparent thermoplastic resin (B) having an absolute value of photoelastic coefficient of 10.0×10 −12 /Pa or less and an absolute value of orientation birefringence of less than 10.0×10 −4 . The Tg of the base material layer is higher than the Tg of the retardation adjusting layer. The Re value of the resin plate is 50 to 330 nm. |
