Abstract: A display device includes: a substrate; a display element layer disposed on the substrate, where the display element layer includes a light emitting element which emits light; a polarizing film disposed on the display element layer, where the polarizing film includes a first polarizer having a first absorption axis extending to a first direction and a first transmission axis extending to a second direction orthogonal to the first direction; and a first layer disposed on one surface of the polarizing film, where the first layer has a first phase difference. Light emitted from the display element layer has a polarizing axis, and an angle between the polarizing axis and one of the first absorption axis and the first transmission axis is in a range of about 25 degrees to about 65 degrees.
