Abstract: A large-area semiconductor device through a single domain and a method of manufacturing the same are disclosed. The method comprises forming an absorption layer on a substrate, forming first sub semiconductor characteristic material layers on the absorption layer in spaces among first sub masks by using a first mask including the first sub masks, forming a second mask including second sub masks on the first sub semiconductor characteristic material layers and forming second sub semiconductor characteristic material layers in spaces among the second sub masks. Here, a large-area semiconductor characteristic material layer is formed on the absorption layer by the first sub semiconductor characteristic material layers and the second sub semiconductor characteristic material layers.

Abstract: A retroreflective piping sheet for vehicle interior decoration includes a fabric layer having a fabric circular-knitted from a ply yarn of polyester and spandex, a retroreflective layer, disposed on a one side of the fabric layer, having a plurality of glass beads therein and a hot melt adhesive layer disposed on the other side side, opposite to the one side, of the fabric layer.

Abstract: Disclosed are a retro-reflective sheet and a method for manufacturing the same. The retro-reflective sheet includes a first protective film, a first thermoplastic bonding layer, a first heat-resistant bonding layer, a colored layer, a light transmitting layer, a colored area allowing a portion of scattered light to be emitted to the outside through a first light condensing layer, a second protective film, a second thermoplastic bonding layer, a second heat-resistant bonding layer, a reflective layer, a reflective area reflecting light input through a second light condensing layer, and a base film.

Abstract: A retroreflective sheet and a fabrication method thereof are provided, the retroreflective sheet including a base, a bonding layer formed on the base, a colored layer formed to be thicker in a non-reflective region NRA2 than in a reflective region RA2 to have a concavo-convex surface on the bonding layer, and having a fluorescent function or a phosphorescent function or having the both fluorescent and phosphorescent functions, a reflective layer formed in the concave portion of the reflective region RA2 on the surface of the colored layer, and a light concentrating layer having a plurality of beads aligned therein on the reflective layer. Thus, since a step is not generated between the reflective region and the non-reflective region, the light reflective member can be prevented from being delaminated from the body when used, and also, the light reflective member can be simply formed in the reflective region of the colored layer.
