An optical component for a display apparatus comprises an optical waveguide part () arranged to guide light therealong between surface parts thereof by internal reflection, an input part () arranged to receive light and direct the received light into the optical waveguide part, and an output part comprising a partially transmissive angularly reflective optical coating () arranged upon a surface part of the optical waveguide part. The output part is optically coupled to the input part by the optical waveguide part to receive guided light and to transmit some but not all of said guided light out from the optical waveguide part. The angularly reflective optical coating extends along a dimension of the optical waveguide part to expand the guided light in said dimension along the output part by repeated partial transmission thereof for output.
