Abstract
A liquid crystal displaying apparatus, a projection displaying apparatus, and a view finder apparatus using the liquid crystal displaying apparatus, are disclosed. Polarizing plates are disposed on the incident side and the outgoing side of a liquid crystal cell so that a twisted nematic liquid crystal is arranged to become approximately 90.degree. in twist angle between two transparent substrates having a picture element electrode. A direction of a phase advancing axis of the phase difference plate with respect to the polarized light axis of the polarizing plate on the incident side is set so that the transmission index of the optical head from the polarizing plate on the incident side to the polarizing plate on the outgoing side may become minimum when a given voltage for black displaying operation is applied on the liquid crystal cell and the light is inputted from the given direction.
