Abstract: A display apparatus includes a polarizer, a phase retardation film, a touch member, and a display panel. The polarizer has a transmitting axis and is configured to linearly polarize external light to be parallel to the transmitting axis. The phase retardation film is on the polarizer and has a first optical axis. The touch member has a second optical axis and comprises a touch substrate on the polarizer and touch electrodes on the touch substrate. The display panel is on the polarizer. When a first in-plane retardation value of the phase retardation film is Rp1, a second in-plane retardation value of the touch member is Rp2, a phase retardation value within a target surface is Rpg, and a is a constant, an equation Rp1=Rpg−a*Rp2 is satisfied.
