Display device

A display device comprising

• a display panel, and
• an optical member positioned on the display panel,
• wherein the optical member comprises:
• 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,
• wherein the first compensation layer is a positive C plate, and a thickness direction phase delay value of the first compensation layer is about −65 nanometers (nm) to about −15 nm,
• the fourth compensation layer is a positive C plate, 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,
• wherein the display panel comprises:
• a substrate;
• a transistor positioned in the substrate;
• a pixel electrode connected to the transistor;
• an emission layer positioned on the pixel electrode;
• a common electrode positioned on the emission layer;
• a buffer electrode positioned between the emission layer and the common electrode;
• a capping layer positioned on the common electrode;
• and
• an encapsulation layer positioned on the capping layer, and
• wherein a thickness direction phase delay value of the display panel is about −40 nm to about 0 nm.
