1. A light field display comprising:
a picture element including multiple sub-picture elements, the multiple sub-picture elements including:
an array of light emitting elements grown directly on a single, continuous semiconductor substrate, the array of light emitting elements including (i) a first light emitting element configured to produce a first color of light, (ii) a second light emitting element configured to produce a second color of light that differs from the first color of light, and (iii) a third light emitting element configured to produce a third color of light that differs from each of the first color of light and the second color of light;
a light steering optical element configured to direct the first color of light, the second color of light, and the third color of light emitted from the array of light emitting elements in a first direction different from a second direction associated with another array of light emitting elements grown directly on the single, continuous semiconductor substrate; and
a backplane including electronic circuits electronically connected with the picture element and configured to individually drive the multiple sub-picture elements.
