There is provided a micro lens array () in which a plurality of micro lenses () is disposed two-dimensionally on a substrate, wherein the focal distance f of the micro lens () and distance Ts from the main surface of the micro lens () to the substrate surface upon which light is incident meet the following/&#x221a;{square root over (2)}/&#x221a;{square root over (2)}where P is a pitch of the micro lenses () and (X, Y) is within an X-Y coordinate system surrounded by the following point sets The micro lens array can be used to improve the contrast of a liquid crystal display having an optical compensation element provided therein.

Liquid crystal display, and projection type display using liquid crystal display layer

A liquid crystal display apparatus which includes an optical compensation layer in addition to a liquid crystal panel and which is capable of preventing degradation of the optical compensation layer, thereby providing high long-term reliability in display characteristics, is provided. The liquid crystal display apparatus includes a liquid crystal panelin which a liquid crystal layeris interposed between a first substrateand a second substrate; a protection substratedisposed at least one side of the liquid crystal panelso as to face the liquid crystal panel; and an optical compensation layerinterposed between the liquid crystal paneland the protection substrate. In addition, the liquid crystal display apparatus further includes polarizing platesanddisposed at either side of the liquid crystal panelon which the protection substrateis provided; an illumination optical system irradiating the liquid crystal panelwith light h through one of the polarizing platesandand a projector lens projecting the light h that passes through the liquid crystal panel
