Patent ID: 7480016

Claim:
An electro-optical device comprising: a first module provided with an electro-optical panel having a polarizer on a side of a display surface of the first module, on which surface an image is displayed; a plate-like second module provided with a reflective polarizer and having at least a translucent portion in area that overlaps with the reflective polarizer in a direction perpendicular to the reflective polarizer; and a hinge portion that couples the first module to the second module, wherein the hinge portion supports the second module so that the second module, when pivoted about a first axis parallel to the display surface, is allowed to be switched between a closed position in which the display surface is covered and an opened position in which the display surface is exposed to an outside, while the hinge portion pivotally supports the second module about a second axis perpendicular to the first axis and parallel to the reflective polarizer, and wherein a polarization axis of the polarizer and a polarization axis of the reflective polarizer each are set in a direction that is not parallel and perpendicular to the first axis.
