Abstract

A display panel comprises a substrate, a gate line, a data line insulated from the gate line, a thin film transistor electrically connected to the gate line and the data line, wherein the thin film transistor comprises a gate electrode group formed on the substrate, a gate insulating film formed on the gate electrode group, an active layer formed on the gate insulating film to at least partially overlap the gate electrode group and a source electrode and a drain electrode formed on the active layer so as to be spaced apart from each other, wherein the gate electrode group includes a first gate electrode formed on the substrate, a second gate electrode formed on the first gate electrode, and an insulating layer between the first gate electrode and the second gate electrode, and wherein the first gate electrode has reflectivity higher than that of the second gate electrode.
