This application provides an image display method and an image display apparatus, and is beneficial to improving uniformity of an image displayed by using a diffractive waveguide, thereby improving user experience. The method is applied to an apparatus including an optical engine and the diffractive waveguide and includes: obtaining uniformity data of a first image obtained by using the diffractive waveguide; determining to-be-compensated data of the optical engine based on the uniformity data; adjusting luminance distribution of a light source in the optical engine based on the to-be-compensated data; and displaying a second image by using the adjusted optical engine and the diffractive waveguide.
