    • PROBLEM TO BE SOLVED: To provide a reflective liquid crystal display device utilizing a ferroelectric liquid crystal. SOLUTION: The reflective liquid crystal display device comprises a transparent first substrate with inside and outside surfaces, a polarizing plate with a polarization direction in a first direction attached on the outside surface of the first substrate, a transparent first electrode formed on the inside surface of the first substrate, a first alignment film formed on the first electrode aligning liquid crystal molecules in a second direction, a second substrate placed opposite to the inside surface of the first substrate with inside and outside surfaces, a second electrode formed on the inside surface of the second substrate simultaneously functioning as a reflection plate, a second alignment film formed on the second electrode aligning the liquid crystal molecules in a third direction different from the second direction and a ferroelectric liquid crystal layer injected between the first and second alignment films. In the device, the directions to which the liquid crystal molecules in the ferroelectric liquid crystal layer are oriented twist from the second to the third direction as the molecules go from the first to the second alignment film surface.
