ABSTRACT:
A first polarizer and a second polarizer have respective absorption axes extending approximately perpendicularly to each other, and a first retardation plate and a third retardation plate have respective slow axes extending approximately perpendicularly to each other. The first retardation plate and the third retardation plate have respective retardations that are approximately equal to each other, and have respective Nz coefficients that are approximately equal to each other. A second retardation plate and a liquid crystal layer in a transmissive display area have a slow axis and an orientation axis, respectively, extending approximately perpendicularly to each other. The second retardation plate and the liquid crystal layer in the transmissive display area have respective retardations that are approximately equal to each other.
