Abstract: The present invention provides a polarizing plate and an image display system capable of lowering the reflectivity and improving the visibility of a public display. The present invention relates to a polarizing plate which is disposed on a visual recognition side of an image display devise that emits circularly polarized light and which converts the circularly polarized light into linearly polarized light. The polarizing plate preferably has a first optical element and a first polarizer in this order from an incident side of the circularly polarized light. The polarizing plate preferably has a ?/4 plate disposed closer to the visual recognition side than the first polarizer.
