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.

A display panel and a display device are disclosed. The display panel includes a display panel body and a polarizer, placed on the display panel body in a direction of outgoing light. The display panel body includes a metal layer having a reflection area corresponding to a first heading angle larger than a reflection area corresponding to a second heading angle. A light extinction of the polarizer corresponding to the first heading angle is greater than a light extinction of the polarizer corresponding to the second heading angle. This could remedy the light extinction of the polarizer in the second heading angle such that the display panel could have similar reflection rates and color shifts in all heading angles.

A display device includes a base, a display panel, and a spacer. The display panel is disposed on the base and has a back surface. The back surface has a central area and a peripheral area closer to the edge of the display panel than the central area. The shortest distance between the central area and the base is greater than the shortest distance between the peripheral area and the base. The spacer is disposed between the base and the back surface corresponding to the central area. The spacer is disposed to raise the central portion of the display panel relative to the edge of the display panel, so the arching configuration of the display panel prevents the edge of the display panel from warping.
