Abstract
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
