Liquid crystal display
A liquid crystal display including: a first substrate; a gate line and a data line formed or otherwise disposed on the first substrate; a drain electrode disposed on the first substrate; a first insulating layer disposed on the gate line and the data line; a first electrode disposed on the first insulating layer; a second insulating layer disposed on the first electrode; and a second electrode disposed on the second insulating layer. The first insulating layer and the second insulating layer have a first contact hole exposing a portion of the drain electrode. The contact portion of the second electrode is connected to the drain electrode through the first contact hole, and the contact portion overlaps the first electrode adjacent the first contact hole. The overlap increases capacitance of the display panel so as to decrease kickback voltage and reduce flicker.
