Abstract

The present disclosure provides a display apparatus. According to the present disclosure, a complex refractive layer is disposed on a side of the polarizer facing away from the electroluminescent display panel, and configured to convert the linearly polarized light into the circularly polarized light, so that the linearly polarized light in different polarization states having passed through the glass enters the complex refractive layer before entering the polarizer, the complex refractive layer converts the linearly polarized light into the circularly polarized light, and when the included angle between the film-forming stretching direction of the complex refractive layer and the first direction is an acute angle, almost all of the circularly polarized light can pass through the polarizer, thus eliminating the Mura phenomenon.
