Abstract: Disclosed are an ionic liquid, an electrolyte including the ionic liquid, and a lithium secondary battery including the same. The ionic liquid is capable of forming a film having high ionic conductivity on an anode upon reductive decomposition of cations contained therein, and delaying the decomposition of anions.

Abstract: The present invention relates to an optical sheet for use in a liquid crystal display. The optical sheet of the present invention allows for ease of handling, reduces defective proportions and manufacturing costs, improves throughput, and prevents the deterioration of luminance attributable to the damage of the optical sheet.

Abstract: Disclosed is an optical sheet for use in liquid crystal displays, which is not easily damaged by external impact, thus facilitating handling thereof and decreasing defective rates, resulting in reduced production costs and increased production efficiency. Decreases in the luminance of the optical sheet due to damage can be prevented.

Abstract: An optical sheet having a structured surface and a composition for forming optical three-dimensional patterns able to form the structured surface, which is not easily damaged by external force or a rough surface and thus facilitates the handling thereof, reduces defective rates to thus decrease the production cost and increase the production efficiency, and prevents a decrease in luminance attributable to damage.

Abstract: A light-emitting device of a portable communication terminal improves exterior decoration by emitting light to the exterior of the portable communication terminal and implements a sense of unity of a design in a non-light emission state by integrating a portion to which the light is transmitted with a main body housing. The light-emitting device includes a housing, a light-emitting element for emitting light, a light guide sheet for guiding the light from the light-emitting element, and a light-transmitting portion integrally formed on the housing for transmitting the light from one end of the light guide sheet to an outer side of the housing. A sense of unity of the main body housing and the light-transmitting portion can be improved by applying a non-conductive vacuum metallizing (NCVM) process to the exterior. An aesthetic sense is improved with the sense of unity of the exterior design.
