1. A liquid crystal display device, comprising:a pair of substrates disposed opposite to each other leaving a predetermined gap therebetween, each of the pair of substrates having an electrode and a liquid crystal orientation control layer, the liquid crystal orientation control layer including an inner surface; and a liquid crystal disposed within said gap, the liquid crystal contacting the inner surface of the liquid crystal control layer of each of said substrates, wherein a plurality of grooves and repetitive asymmetrical projections are formed on the inner surface of the liquid crystal orientation control layer of each of said substrates and each of said plurality of grooves has a radius of curvature of at least 0.1 .mu.m; a depth D1 of each of said plurality of grooves, a height D2 of each of said asymmetrical projections, a pitch A1 of each of said plurality of grooves, and a pitch A2 of each of said asymmetrical projections are related as follows: RE=(D12/A13)/(D22/A23)≥4.4; and when a distance between a starting point and a peak point of said each of the asymmetrical projections parallel to said each of the plurality of grooves is expressed by a and a distance between said peak point and a terminating point of said each of the asymmetrical projections is expressed by b and a/b is greater than 1 and equal to or less than 2, and wherein the liquid crystal is of a ferroelectric type.
