1. A light emitting display comprising:
a light emitting area of a film-based lightguide frontlight positioned between a cover lens and a reflective spatial light modulator, the cover lens extends past a lateral edge of the reflective spatial light modulator;
and a housing positioned below the cover lens in a thickness direction of the film of the film-based lightguide frontlight and along one or more lateral edges of the reflective spatial light modulator and positioned in an edge region defined between the lower surface of the cover lens and a lower surface of the reflective spatial light modulator, and between the lateral edge of the reflective spatial light modulator and a distance from the lateral edge of the reflective spatial light modulator in a first direction in a plane orthogonal to the thickness direction equal to the distance the cover lens extends past the lateral edge in the first direction.
