Latest Patents

Yamaguchi's latest patents include a light-emitting device and an image display apparatus. The objective of this invention is to provide an image display apparatus that can inhibit or prevent the deterioration of a light conversion layer while achieving high luminous efficiency and color reproducibility. The invention features a light-emitting device that includes a pair of electrodes and an electroluminescent layer. This layer is situated between the first and second electrodes, along with a light conversion layer that consists of multiple pixels. These pixels convert light emitted from the electroluminescent layer, which has a blue emission spectrum, into light of a different wavelength. The light conversion layer comprises pixels of the three primary colors: red (R), green (G), and blue (B). It contains light-emitting nanocrystals that emit light in any of these primary colors when stimulated by the light from the electroluminescent layer.

Another significant patent involves a dispersion and inkjet ink composition, which includes a light conversion layer and a liquid crystal display element. This dispersion contains essential ingredients such as light-emitting nanocrystals, a polymeric dispersant with an amine value of 5 mg/KOH g or more, and a stimulation-responsive curable material that cures in response to external stimuli.
