Abstract:
1. A liquid crystal display comprising: a back substrate which comprises a first substrate, a first electrode disposed on a main surface of the first substrate, and a first alignment layer covering the first electrode and including a first corrugated surface at a position of the first electrode, wherein the first corrugated surface includes first upslopes and first downslopes steeper than the first upslopes or first vertical surfaces which are alternately joined in an in-plane direction parallel to the main surface of the first substrate, and wherein a period of the first upslope in the in-plane direction is 1 μm or less; a front substrate which comprises a second substrate facing the first alignment layer, a second electrode disposed on a main surface of the second substrate facing the first alignment layer, and a second alignment layer covering the second electrode and including a second corrugated surface at a position of the second electrode, wherein the second corrugated surface includes second upslopes and second downslopes steeper than the second upslopes or second vertical surfaces which are alternately joined in the in-plane direction, and wherein a period of the second upslope in the in-plane direction is 1 μm or less; and an optical filter layer interposed between the back and front substrates and containing a liquid crystal material which forms a bend configuration when a voltage is applied between the first and second electrodes.
