Abstract
Provided is a display apparatus including a circuit substrate, a light-emitting layer, a polarizing layer, a quarter waveplate, and a bandpass polarizing reflective layer. The light-emitting layer includes a plurality of first light-emitting structures. The first light-emitting structures have a first peak emission wavelength. The polarizing layer is located on a side of the light-emitting layer away from the circuit substrate. The quarter waveplate is disposed between the polarizing layer and the light-emitting layer and overlaps the light-emitting layer and the polarizing layer. The bandpass polarizing reflective layer is disposed between the quarter waveplate and the light-emitting layer and includes a first bandpass polarizing reflective pattern overlapping the first light-emitting structures. A reflectance of the bandpass polarizing reflective pattern for light with a wavelength in a first wavelength range is greater than 20%. The first wavelength range is the peak emission wavelength ±10 nm.
