Claim Text:
1. A liquid crystal display, comprising a liquid crystal unit as well as a first polarizing sheet and a second polarizing sheet each provided at either side of the liquid crystal unit, in which an absorption axis of the first polarizing sheet is perpendicular to an absorption axis of the second polarizing sheet; wherein the liquid crystal unit comprises: a counter substrate and an array substrate as well as a liquid crystal layer lying between the two substrates, in which, the array substrate comprises a pixel electrode and a common electrode; the first polarizing sheet is an optical-compensation polarizing sheet, and the first optical-compensation film of the first polarizing sheet is provided facing a side of the liquid crystal unit where the counter substrate is located; the absorption axis of the first polarizing sheet and an initial alignment direction of the liquid crystal in the liquid crystal layer are both perpendicular to the slow axis of the first optical-compensation film; the second polarizing sheet comprises: an isotropic protective film as well as a second polarizing film affixed to the isotropic protective film, in which, the isotropic protective film is provided proximate to a side of the liquid crystal unit where the array substrate is located; wherein, the optical-compensation polarizing sheet comprises: a first optical-compensation film as well as a first polarizing film affixed to the first optical-compensation film; wherein within a visible light wavelength range, the first optical-compensation film has an in-plane retardance R when the liquid crystal display is an IPS-mode liquid crystal display, the pixel electrode and the common electrode are provided in a same layer, and they both comprise a plurality of electrically-connected strip-like electrodes; the strip-like electrodes of the pixel electrode, as well as the strip-like electrodes of the common electrode, are provided at intervals; or, the pixel electrode and the common electrode are provided in different layers, and the common electrode and the pixel electrode do not overlap along an orthogonal-projection direction vertical to the substrate surface; when the liquid crystal display is an FFS-mode liquid crystal display, the pixel electrode and the common electrode are provided in different layers; the common electrode lying in an upper layer is formed to comprise a plurality of electrically-connected strip-like electrodes; meanwhile, the pixel electrode and the common electrode have an overlapping portion along an orthogonal-projection direction vertical to the substrate surface.
