Abstract: The present disclosure discloses a liquid crystal composition. The liquid crystal composition includes the following components in their respective mass percentages: 8%-50% of a polymerizable liquid crystal monomer; 1%-30% of a chiral reagent; 0.1%-5% of a photoinitiator; and 30%-70% of an organic solvent, wherein the liquid crystal composition after being cured exhibits visual angle dependent optical effect. In this way, the liquid crystal composition of the present disclosure includes no pigment particles or liquid crystal microcapsules, can be UV cured into film, and is applicable to being printed onto various substrates through gravure or flexo printing, so that it has a promising application prospect.

Abstract: A substrate used for III-V-nitride growth and a manufacturing method thereof, the manufacturing method comprising the following steps: 1) providing a growth substrate, and forming on the surface of the growth substrate a buffer layer used for subsequent growth of a luminescent epitaxial structure; 2) forming a semiconductor dielectric layer on the surface of the buffer layer; 3) by means of a photolithography process, etching a plurality of semiconductor dielectric protrusions arranged at intervals on the semiconductor dielectric layer, and exposing the buffer layer between the semiconductor dielectric protrusions. This method ensures the crystal quality of the grown luminescent epitaxial structure and also raises the luminescent efficiency of a light-emitting diode. The process is simple, advantageous for reducing cost of manufacture, and suitable for use in industrial production.
