Abstract: A display device includes: a display panel and an optical member positioned on the display panel. The optical member includes: a polarization layer positioned on the display panel; a first compensation layer positioned between the display panel and the polarization layer; a second compensation layer positioned between the display panel and the first compensation layer; a third compensation layer positioned between the display panel and the second compensation layer; and a fourth compensation layer positioned between the display panel and the third compensation layer. The first compensation layer is a positive C plate and a thickness direction phase delay value of the first compensation layer is about −65 nm to about −15 nm, and the second compensation layer is a positive A plate and an in-plane phase delay value of the second compensation layer is about 75 nm to about 125 nm.
