Abstract
Discussed is a display apparatus that can include an encapsulation unit covering a light-emitting device and an optical unit on the encapsulation unit. The optical unit can control viewing angle of the light emitted from the light-emitting device. For example, the optical unit can include a linear polarizer, a dichroic dye layer disposed on the linear polarizer and an optical compensation layer disposed between the linear polarizer and the dichroic dye layer. Thus, in the display apparatus, the viewing angle of the dichroic dye layer can be compensated by an in-plane phase retardation value (Rin) and/or a thickness direction phase retardation value (Rth) according to a type of the optical compensation layer.
