An active matrix display device includes a pair of substrates, an optical modulation layer lying between the substrates, a plurality of pixel electrodes on one of the substrates, switching elements for driving the respective pixel electrodes provided in the vicinity of the pixel electrodes, and a reflective or transflective reflecting layerformed on at least one substrate more distant from a viewer side. The reflecting layer has asymmetrical reflection properties.

An orientation film for a liquid crystal display. The film is formed on a substrate and has a first irregular form repeated in a first direction and a second irregular form repeated in a second direction, which is perpendicular to the first direction. The second irregular form has a longer pitch than the pitch of the first irregular form. The profile of the second irregular form in any plane perpendicular to the first direction has a portion inclined with respect to the substrate. The pretilt angle of the orientation film is high. The patterns may be irregular and asymmetric, which may be ridges separated by a continuous groove. The orientation may be formed by using a first mold having one of the patterns, and a second mold with a second pattern, or first and second holographic exposed layers. The orientation layer may be a liquid crystal polymer which is formed by using a heated stamper to form a pattern in a high polymer liquid crystal while applying a voltage.

A liquid crystal display includes a pair of substrates and a liquid crystal composition sealed between the substrates. The liquid crystal composition has a twist angle set within a range of 180-300 degrees and a retardation set within a range of 0.45-0.7 .mu.m wherein when an electric field is applied, the liquid crystal display is in a dark state, while when the electrid field is not applied, the liquid crystal display is in a bright state. A dichromatic coloring matter is contained in the liquid crystal composition, and it has a hue complementary to that of an image color of the liquid-crystal display in the bright state.

A liquid crystal display includes a pair of substrates and a liquid crystal composition sealed between the substrates. The liquid crystal composition has a twist angle set within a range of 180-300 degrees and a retardation set within a range of 0.45-0.7, wherein when an electric field is applied, the liquid crystal display is in a dark state, while when the electric field is not applied, the liquid crystal display is in a bright state. A filter is laminated on the outside of the substrates, and it has a hue complementary to that of an image color of the liquid crystal display in the bright state.
