Liquid crystal display device and manufacturing method thereof

Abstract

Disclosed is a liquid crystal display device which can be used in a variety of situations and applications. The liquid crystal display device comprises: a first substrate comprising a first display region, a second display region, and a third display region wherein the first display region, the second display region, and the third display region are continuously formed; a second substrate having a form which fits the first substrate; and a liquid crystal interposed between the first substrate and the second substrate. The second display region is interposed between the first display region and the second display region. The second display region is curved, and the first display region and the second display region are substantially flat.
