20100157177 | APPARATUS AND METHOD OF DISPLAYING AN IMAGE - A display apparatus includes a display panel, a first polarization part, and a second polarization part. The display panel includes an array substrate, an opposite substrate and an electro-optical material layer disposed between the array substrate and the opposite substrate. The electro-optical material layer reflects first circularly polarized light having a wavelength of a predetermined range and transmits second circularly polarized light having a phase difference with the first circularly polarized light. The first polarization part faces a rear face of the array substrate and converts incident light of the rear face into the first circularly polarized light. The second polarization part faces a front face of the opposite substrate and blocks the first circularly polarized light reflected from the electro-optical material layer and transmits the second circularly polarized light transmitted through the electro-optical material layer. | 06-24-2010 |
