MULTILAYER PHASE DIFFERENCE PLATE, POLARIZING PLATE, AND IMAGE DISPLAY DEVICE
A phase difference plate includes a phase difference plate P1 and a phase difference plate P2. An in-plane slow axis of the phase difference plate P1 is orthogonal to an in-plane slow axis of the phase difference plate P2. The phase difference plate P2 includes a layer of a liquid crystal material oriented in an in-plane direction. An in-plane retardation ReP2(λ) at a wavelength λ nm of the phase difference plate P2 satisfies the following formulae (e1) and (e2): {Re2(400)−Re2(550)}/{Re2(550)−Re2(700)}<2.90 (e1), and Re2(400)/Re2(700)>1.13 (e2). An in-plane retardation ReP1(λ) of the phase difference plate P1 at a wavelength λ nm and the in-plane retardation ReP2(λ) of the phase difference plate P2 at the wavelength λ nm satisfy the following formulae (e4) and (e5): ReP1(550)>ReP2(550) (e4), and ReP1(400)/ReP1(700)<ReP2(400)/ReP2(700) (e5).
