Embodiments of the invention provide an AR display device and wearable AR equipment. A cured halving reflector is arranged, and includes a curved mirror substrate and a semi-permeable and semi-reflective film; and the semi-permeable and semi-reflective film is located on the side, back to a spectroscope, of the curved mirror substrate, so that the curved mirror which is originally reflected only once can increase refraction and reflection. Thus, the number of refraction surfaces can be increased under the premise that the system volume remains unchanged, so that degrees of freedom of design can be enhanced, bases can be provided for reducing aberration and enhancing optical performance, and the definition of an imaging system can be higher and viewing angles can be larger while the volumeis decreased.
