Liquid crystal display with electrostatic-resistant wirings

摘要

A liquid crystal display includes a first substrate and a second substrate facing each other, common voltage wiring disposed on the first substrate and transmitting a common voltage, a first insulating layer disposed on the common voltage wiring, a common electrode disposed on a whole surface of the second substrate, a first conductive member disposed between the first substrate and the second substrate and electrically connecting the common electrode and the common voltage wiring to each other, and a sealant combining the first substrate and the second substrate. The first insulating layer includes a first contact hole exposing a first portion of the common voltage wiring and a plurality of a second contact hole exposing a second portion of the common voltage wiring, the second contact hole having a smaller area than the first contact hole.
