Abstract

An optical waveguide device, a display apparatus, and a display device are disclosed. The optical waveguide device includes an optical waveguide dielectric body, a first polarized reflection layer, and an optical structure layer. The optical waveguide dielectric body includes a first surface and a second surface opposite to each other, the first polarized reflection layer is arranged on the first surface, and the optical structure layer is arranged on the second surface. The optical waveguide dielectric body is configured to propagate light, which includes a first polarized light. The first polarized reflection layer is configured to reflect the first polarized light and transmit a second polarized light. The optical structure layer is configured to convert the first polarized light incident at a preset angle into the second polarized light, reflect the second polarized light to the first polarized reflection layer, and reflect the first polarized light incident at another angle to the first polarized reflection layer. An exit region of the second polarized light is no longer limited to a region without a reflective film layer, thereby increasing a light exit range of the optical waveguide device.
