<p>A polarizer (11) is disposed through a twist phase plate (12) on the viewed side of a liquid crystal element (21) including a reflective layer (7). The direction of the twist phase plate (12) is opposite to that of the liquid crystal element (21). The alignment angle α of the twist phase plate (12) is in the range from 80 to 100° ; and that $g (b) of the polarizer (11) is in the range from 60 to 75° . The twist angle Tc of the twist phase plate (12) is 0.7 to 0.8 times that Ts of the liquid crystal element (21). The twist phase plate (12) exhibits a birefringence Δnd (Rc) 0.1 to 0.15 νm smaller than Δnd (Rs) of the liquid crystal element (21). As a result, high contrast of reflection display is achieved.</p> |
