According to one embodiment, a display device includes an optical switch panel, and a light source device. The optical switch panel includes pixels and a drive part controlling transmissivity of the pixels. The light source device is stacked with the panel and includes a light source to emit a source light, a light guiding unit, interference filters, and light controlling parts. The light guiding unit includes a light guide region guiding the source light, a reflecting part provided around the region to reflect the source light, and apertures provided around the region and causing semi-collimated light to be emitted. The interference filters cause lights in certain wavelength dands of the light emitted from the aperture to pass. The light controlling parts cause the lights through the filters to enter the pixels to form an image.

According to one embodiment, in an organic electroluminescence device, a first substrate has a first refractive index n1. A second substrate is joined to an upper surface of the first substrate and has a second refractive index n2 higher than the first refractive index n1. Multiple wedge-shaped metal lines are buried in the second substrate in such a manner that one side of the wedge-shaped metal line is flush with an upper surface of the second substrate. A transparent electrode is formed on the upper surface of the second substrate and the multiple metal lines. An insulating layer is formed on a portion of the transparent electrode opposed to the multiple metal lines. An organic light emitting layer is formed on the transparent electrode on which the insulating layer is formed. A metal electrode is formed on the organic light emitting layer.
