Abstract
A dual-image flat display device includes a first and a second substrates parallel with each other, a liquid crystal layer having liquid crystal molecules, and at least a pixel disposed on the second substrate. The pixel includes pluralities of sub-pixels arranged side by side along a first direction. Each sub-pixel has a first azimuthal angle domain and a second azimuthal angle domain, wherein the first and second azimuthal angle domains are arranged side by side along a second direction in the sub-pixel, and the second direction is not parallel with the first direction. The azimuthal angles of liquid crystal molecules in the first and second azimuthal angle domains have an included angle less than 180°.
