Abstract
A liquid crystal display apparatus includes a liquid crystal element including a front substrate positioned on the side of an observer and having a first electrode mounted to one surface, a rear substrate having a second electrode arranged to face said first electrode, and a liquid crystal layer interposed between these substrates, said liquid crystal layer controlling the polarized state of the transmitted light in accordance with the electric field applied between the first and the second electrodes. A first reflection polarizing plate is arranged on the front side of the liquid crystal element and reflects the light of one of the two polarized components of the incident light. Two polarized components are perpendicular to each other, and transmit the light of the other polarized component.
