Abstract
A light-emitting module includes a light-guiding plate, a plurality of light-guiding elements and a light-emitting unit. The light-guiding plate can guide the direction of light, and has at least a light input surface and two opposite flat surfaces. The light-guiding elements are disposed at one of the surfaces of the light-guiding plate. By viewing along a direction perpendicular to the surfaces, the shape of each of the light-guiding elements is curve shape with at least one inflection point. The light-emitting unit is disposed adjacent to the light input surface of the light-guiding plate. The light emitted by the light-emitting unit enters the light-guiding plate, is guided by the light-guiding plate and the light-guiding elements, and is outputted through one of the surfaces of the light-guiding plate in an alternating arrangement of bright and dark zones. The invention also discloses a display apparatus and the light-guiding plate.
