Display system

A display system, comprising:

• a display that emits, from a display surface, light corresponding to image information;
• a half mirror that receives the light emitted, reflects, as reflected light, a first component of the light received, and transmits a second component of the light received, the second component being different from the first component;
• and
• a first reflecting mirror having a concave surface that receives and reflects the reflected light toward the half mirror, wherein
• the half mirror includes a first retardation film, a first support substrate, and a reflective polarizing film stacked in this order from a side on which the light emitted is received, the first retardation film changing a phase of the light received, the first support substrate being light-transmissive, the reflective polarizing film reflecting a first polarized component and transmitting a second polarized component different from the first polarized component.
