Abstract

Disclosed is a liquid crystal display panel which includes a first substrate, a thin film transistor array comprising at least one thin film transistor formed on a first surface of the first substrate, and a second substrate having a first surface facing the first substrate, the second substrate including an antistatic layer on a surface opposite the first surface of the second substrate. Liquid crystal molecules are positioned between the first surface of the first substrate and the first surface of the second substrate, wherein the antistatic layer includes conductive nanowire.
