Abstract
To improve the display uniformity in a vertical alignment liquid crystal display. A liquid crystal display includes: first and second substrates; first and second electrodes provided the substrates, respectively; first and second vertical alignment films provided on the substrates respectively; a plurality of columnar spacers disposed at least in a region where the first and second electrodes are superimposed, and provided between the first and second substrates; and a liquid crystal layer provided between the first and second substrates. The first vertical alignment film is subject to an alignment treatment in one direction. The liquid crystal layer has a pretilt angle during non-application of voltage. Each columnar spacer has a profile, in a planar view, which is not orthogonal to and which is not parallel with an alignment direction of liquid crystal molecules at substantially center of the liquid crystal layer in a layer thickness direction.
