The present invention relates to a method of manufacturing a hyaluronate film and a hyaluronate film manufactured thereby, and more particularly to a method of manufacturing a hyaluronate film through a solvent-casting process or using an automatic film applicator that facilitates mass production and to a hyaluronate film manufactured thereby, which is useful as a mask pack for cosmetics, a patch for medicaments and medical devices, a film-type adhesion inhibitor, etc. Unlike conventional liquid products, the hyaluronate film according to the present invention has a dry surface and thus entails no concern about microbial contamination, is easy to produce/manage/distribute/use, and has superior mechanical properties, whereby it can be utilized for various applications such as packs, patches, artificial skin and the like for cosmetics, medicaments, and medical devices.

Method for manufacturing hyaluronate film, and hyaluronate film manufactured thereby

An embodiment comprises: a substrate having a chip mounting region; first and second wiring layers disposed on the substrate around the chip mounting region so as to be spaced apart from each other; and a plurality of light emitting chips disposed on the chip mounting region, wherein the first wiring layer comprises a first wiring pattern disposed at one side of a reference line and having a first concave part, and a first extending pattern extending from the first wiring pattern to the other side of the reference line, the second wiring layer comprises a second wiring pattern disposed at the other side of the reference line and having a second concave part, and a second extending pattern extending from the second wiring pattern to one side of the reference line, and the reference line is a straight line passing through the center of the chip mounting region.
