  • Patent number: 11994774
    Abstract: In an electro-optical device, a first polarizing element, a first phase difference element, a transmissive liquid crystal panel, a second phase difference element, and a second polarizing element are sequentially arranged. Here, when a phase difference of the first phase difference element and the second phase difference element is ?/4, an influence of orientation disorder of liquid crystal molecules can be alleviated, but a contrast ratio is reduced. Therefore, when a wavelength of incident light is ?, a phase difference R of the first phase difference element and the second phase difference element satisfies the following condition that 0<R<?/4, preferably ?/12<R<?/6. For example, it is assumed that the phase difference R is ?/8.
