Abstract

Provided are a light emitting device and a display device. The light emitting device includes a light source, a light splitting element and a beam shaper. The light splitting element includes a light receiving surface on which the light is incident, for dividing the incident light into a plurality of beam groups each having a predetermined width and a predetermined interval between the beam groups. The beam shaper is arranged between the light source and the light splitting element. Light from a light source is incident on the beam shaper, and light emitted from the beam shaper is parallel and has a cross-sectional shape corresponding to the shape of the light receiving surface of the light splitting element.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2006-0070295 filed with the Korean Intellectual Property Office on Jul. 26, 2006, which is hereby incorporated by reference. technical field [0002] An apparatus according to the present invention relates to a light emitting device that splits light into a plurality of monochromatic light beams so that each light beam corresponds to one pixel, and a display device employing the light emitting device with improved light use efficiency. Background technique [0003] Flat panel displays are classified into emissive type displays that form images by emitting light by themselves or non-emissive type displays that form images by receiving light from an external source. For example, a non-emissive flat panel display device such as a liquid crystal display (LCD) requires an additional light source, such as a backlight unit. [0004] Since the non-emissive flat panel display device cannot effectively utili...
