There is provided an optical device that provides a high quality image. The optical device includes a first light guiding member that has first through sixth surfaces and a first deflecting means. The first, second, and fifth surfaces are opposed to the third, fourth, and sixth surfaces, respectively. The optical device further includes a second light guiding member that has seventh through twelfth surfaces and a second deflecting means. The seventh, eighth, and eleventh surfaces are opposed to the ninth, tenth, and twelfth surfaces, respectively. Light that enters from the fifth surface is totally reflected within the first light guiding member, is deflected by the first deflecting means, is emitted from the third surface, enters the eighth surface, is totally reflected between the seventh surface and the ninth surface, is deflected by the second deflecting means, and is emitted from the seventh surface.
