Abstract

A diffraction optical component for a wearable displaying device is provided. The wearable displaying device includes a micro display for generating imaging light. The diffraction optical component includes a light guide plate, a first polarization volume grating (PVG) layer, a second PVG layer, and a third PVG layer. The light guide plate includes a first area, a second area, and a third area arranged on a surface thereof in sequence. The first PVG layer is formed on the first area. The second PVG layer is formed on the second area. The third PVG layer is formed on the third area. A thickness of the first PVG layer is greater than that of the second PVG layer, and is also greater than that of the third PVG layer.
