Abstract:
A liquid crystal display apparatus includes a liquid crystal cell; a first polarizer arranged on a back surface side of the liquid crystal cell; a second polarizer arranged on a viewer side of the liquid crystal cell; a cover sheet arranged on a viewer side of the second polarizer, the cover sheet having a transmission portion at a position corresponding to a display region of the liquid crystal cell; a first optical compensation layer arranged on a viewer side of the cover sheet, the first optical compensation layer having an Re(550) of from 100 nm to 180 nm; and a third polarizer arranged on a viewer side of the first optical compensation layer, wherein an angle formed by a slow axis direction of the first optical compensation layer and an absorption axis direction of the third polarizer is from 35° to 55° or from 125° to 145°.
