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 panel1in which a liquid crystal layer30is interposed between a first substrate10and a second substrate20; a protection substrate3disposed at least one side of the liquid crystal panel1so as to face the liquid crystal panel1; and an optical compensation layer5interposed between the liquid crystal panel1and the protection substrate3. In addition, the liquid crystal display apparatus further includes polarizing plates110and110disposed at either side of the liquid crystal panel1on which the protection substrate3is provided; an illumination optical system irradiating the liquid crystal panel1with light h through one of the polarizing plates110and110,and a projector lens projecting the light h that passes through the liquid crystal panel1.
