  • Publication number: 20200106041
    Abstract: A self light-emitting display device includes a substrate having a circuit board and a color filter pattern on the circuit board. The circuit board includes a driving thin-film transistor. The display device further includes a passivation film above the substrate, a color conversion pattern above the passivation film and overlapping the color filter pattern, and a light-emitting layer above the passivation film and the color conversion pattern. The light emitting layer includes a flat part and a convex part. The convex part is above the color conversion pattern and protrudes convexly relative to the flat part.

  • Patent number: 10459167
    Abstract: The present disclosure relates to an optical fiber capable of converting a wavelength of a light emitted from a light source and a backlight unit using the same. According to the present disclosure, it is possible to extract a light of a desired wavelength band or a desired color (for example, a white light) by connecting an optical fiber, to which a color conversion material is applied, to a single laser light emitting element that emits a light of a specific wavelength band.
