Abstract:
1. A liquid crystal display apparatus comprising: a first substrate; a second substrate; a reflective polarizer, mounted on said first substrate and having a first transmission axis and a first reflection axis at right angles to each other, for transmitting linearly polarized light vibrating in a plane parallel to said first transmission axis and for reflecting linearly polarized light vibrating in a plane parallel to said first reflection axis; a polarizer, mounted on said second substrate and having a second transmission axis, for transmitting linearly polarized light vibrating in a plane parallel to said second transmission axis; and a liquid crystal layer provided between said first and second substrates, and having a first mode which causes the direction of polarization of incident light to change by utilizing birefringence and a second mode which does not utilize birefringence and therefore does not cause the direction of polarization of incident light to change, wherein
