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 device1, a polarizing sheet130surrounds a virtual axis line L extending vertically substantially in the center of the liquid-crystal panel100. A portion of the cylindrical polarizing sheet centered on the virtual axis line L adjacent to the back face of the liquid-crystal panel100is defined as a first polarizer140and a portion of the cylindrical polarizing sheet centered on the virtual axis line L adjacent to the front face of the liquid-crystal panel100is defined as a second polarizer150. As a result, the first polarizer140and the second polarizer150are disposed in cross-Nicol arrangement.
