Liquid crystal display panel and liquid crystal display apparatus

Abstract

The present invention provides a liquid crystal display panel and a liquid crystal display apparatus that features sufficiently fast response and are excellent in transmittance performance. The liquid crystal display panel includes a first substrate, a second substrate, and a liquid crystal layer sandwiched between the first substrate and the second substrate.
