Abstract
To provide an electro-optical device displaying high-contrast images in all directions due to the orthogonality of the polarization axes of the polarizers by improving the structure of the polarizers, and an electronic apparatus including the same. In an electro-optical device, a polarizing sheetsurrounds a virtual axis line L extending vertically substantially in the center of the liquid-crystal panel. A portion of the cylindrical polarizing sheet centered on the virtual axis line L adjacent to the back face of the liquid-crystal panelis defined as a first polarizerand a portion of the cylindrical polarizing sheet centered on the virtual axis line L adjacent to the front face of the liquid-crystal panelis defined as a second polarizer. As a result, the first polarizerand the second polarizerare disposed in cross-Nicol arrangement.
