Abstract: A liquid crystal display (LCD) includes two glass substrates, a liquid crystal unit formed by sandwiching a liquid crystal layer between the two glass substrates, a first polarizing film, and a second polarizing film. In another example, the LCD further includes a diffuse reflective film formed on the other side of the second polarizing film. In another example, the second polarizing film is replaced by a reflective film. The liquid crystal layer is composed of an antiferroelectric (including intermediate antiferroelectric) smectic liquid crystal material, and a birefringence of the liquid crystal layer changes along with an electric field applied to the liquid crystal layer.
