Abstract
Disclosed is a luminance-enhanced film. The luminance-enhanced film includes an intermediate layer comprising a birefringent island-in-the-sea yarn and a sheet laminated on both sides of the intermediate layer, wherein the interface between the intermediate layer and the sheet has an air-gap area ratio of 5% or less, and is characterized in that it is substantially free of curling and does not contain bubbles, thus exhibiting considerably superior optical efficiency and adhesion force. A liquid crystal display utilizing the luminance-enhanced film also advantageously exhibits considerably improved luminance.
