The second layer is opposed to the first layer, and the second layer includes a first element, a second element, and a third element which are arranged periodically to correspond to the first pixel, the second pixel, and the third pixel, respectively, and separate emission light to light of wavelength corresponding to a first color, light of wavelength corresponding to a second color, and light of wavelength corresponding to a third color to be emitted on the first pixel, the second pixel, and the third pixel, respectively.

An integrated back light unit can include a light guide plate having a non-uniform distribution of extraction features. The non-uniform distribution of the extraction features can be provided by an extraction-feature-free region in proximity to a light emitting device, and/or by a variable density of the extraction features that changes with distance from the light emitting device. Additionally or alternatively, the light guide unit can include a heterogeneous reflectivity surface that has a different reflectivity at proximity to the light emitting device assembly than at a distal portion of the light guide unit. The different reflectivity may be provided by a specular reflective material, diffusive reflective material, or a light absorbing material. The non-uniform distribution of extraction features and/or the heterogeneous reflectivity surface can be employed to enhance brightness uniformity of the reflective light and/or to control the temperature distribution within the light guide unit.

A light-emitting module includes a light-guiding plate having an upper surface with a first hole and having a rectangular shape in a top view, and a light-emitting element opposite to the first hole and disposed opposite to the upper surface. The first hole includes a first portion and a second portion between the first portion and the upper surface. The first portion is provided with a first opening at a boundary between the first portion and the second portion and a first lateral surface inclined with respect to the upper surface. A shape of the first opening in the top view is defined by a first axis parallel to a short side of the rectangular shape of the light-guiding plate and a second axis parallel to a long side of the rectangular shape and shorter than the first axis in a plan view.

A lightguide functioning as a luminaire. The luminaire includes at least one solid state light source, such as an LED, and a lightguide configured to receive light from the solid state light source. Light from the light source is coupled into the lightguide and transported within it by total internal reflection until the light exits the lightguide. A shape of the lightguide causes and directs extraction of the light, and can also be used to create a particular pattern of the extracted light. Such shapes include linear wedges and twisted wedges. Optical films can be included on the light input and output surfaces of the lightguide.

A display device includes a display panel, a light source which generates light, a light guide plate which receives the light and guides the light to the display panel, the light guide plate defining a side surface thereof, an accommodating member accommodating the light source and the light guide plate therein, the accommodating member including a sidewall, and a fixing member in plural between the sidewall of the accommodating member and the side surface of the light guide plate. The fixing member defines a supporting portion thereof contacting the side surface of the light guide plate, fixing portions fixed to the sidewall of the accommodating member and spaced apart from each other, and a connecting portion provided in plural and connecting an end among opposing ends of the supporting portion to a fixing portion among the fixing portions, the fixing portion forming an acute angle with the connecting portion.

Architectures are provided for selectively outputting light for forming images, the light having different wavelengths and being outputted with low levels of crosstalk. In some embodiments, light is incoupled into a waveguide and deflected to propagate in different directions, depending on wavelength. The incoupled light then outcoupled by outcoupling optical elements that outcouple light based on the direction of propagation of the light. In some other embodiments, color filters are between a waveguide and outcoupling elements. The color filters limit the wavelengths of light that interact with and are outcoupled by the outcoupling elements. In yet other embodiments, a different waveguide is provided for each range of wavelengths to be outputted. Incoupling optical elements selectively incouple light of the appropriate range of wavelengths into a corresponding waveguide, from which the light is outcoupled.
